e a rBy Nancy J. KnepperAST April, thanks to the efforts of Professors L. T.i Grose, R. G. Weimer, R. C. Epis, and R. H. DeVoto,the National Aeronautics and Space Administration approvedthe CSM proposal to establish a remote sensor testsite for geology in the Bonanza District of south-centralColorado. The NASA-funded grant, which we caU theBonanza Project, was conceived to test and develop theapplications of remote sensing to geological analysis andto further education in remote sensing. At present. ProfessorsR. G, Reeves (Principal Investigator) and KeenanLee (Associate Principal Investigator) are charged withdirecting the progress of the project and supervising theresearch, as well as providing instruction in remote sensingcourses.The area chosen for the Bonanza Test Site is in southcentralColorado (Figure 1). In this one compact regionare encompassed fundamental and economically importantgeologic features which are being studied by conventionalfield methods and by analysis of remote sensor data,The greatest progress during the first year has occurredin broadening the base of geologic knowledge of the siteitself. In part, this consisted of correlation and synthesisof local studies into a regional geologic framework and inpart it was the investigation of critical formerly unmappedareas.GEOLOGY OF THE BONANZA AREAThe wen-exposed rocks in the area include: metamorphicbasement terrain of Precambrian age; sedimentarystrata consisting of conglomerates, sandstones, shales, andlimestones, which together aggregate more than 15,000feet; shallow intrusive and extrusive volcanic flows andtuffs; granitic plutons; and thick alluvial basin-fill deposits.The Bonanza area is traversed by the northern terminusof one of the most extensive Recent fault zones in theU. S.—the Rio Grande rift zone—which extends northwardfrom Mexico into Colorado. This and other structures havea direct relation to. if not major control over, the occufrenceand movement of groimd water in the area. Olderfault systems, in combination with volcano-tectonic collapsefeatures, relate to metallic mineralization in theBonanza, Cotopaxi, Leadville, and other mining districts.Part of the geologic field work during the past year hasbeen concentrated on determining the detailed geologyof three specific areas. These three areas — the RioGrande rift zone, the Bonanza mining district, and theSargents area—are critical to an understanding of Bonanzaregional geology, and these are the main areaswhich will be correlated with remote sensor data obtainedfrom NASA flights 101 and 105, toi be discussed later.Work is currently in. progress to compile a comprehensiveindex map of all geologic mapping done in the Bonanzaarea. The entire area has been mapped on a reconnaissancescale (smaller than 1:250,000); at least 30per cent has been mapped in detail (1:62,500 or larger).Detailed mapping has been concentrated in areas of economicmineralization, such as the Leadville and Bonanzamining districts, and areas where Phanerozoic sedimentaryrocks crop out. Only a small portion of the Precambrianterrain has been mapped in detail. Much of the Sangre deCristo Range has been studied in detail because of thecombination of interesting structure, Pennsyivanian-Permianstratigraphic problems, and excellent exposures. TheIndex map ol Bonania Area in South-Cenfral Coloado.Figure 1.COLORADO01N E W M E X I C Ow mMfoothills region along the eastern flank of the Wet Mountainsand Front Range, mcluding the Canon City re-entrant,has also received much attention.ACQUISITION OF REMOTE SENSOR DATAProblems have arisen in getting remote sensor datato work with, due to difficulty in scheduling of over-flightsand uncooperative weather. Some of the flights havebeen successfully completed, however;1) A NASA-Ames Convau- 990 flew two^ lines of sidelookingairborne radar (SLAR) in the Bonanza area onMay 19, 1969. This was part of a test mission for.' theVenus Fly-By radar system, a long-wavelength SLAR.2) Mission 101 was two flights over the Bonanza areain August, 1969, to obtain photographic coverage, nighttimethermal infrared imagery, and daytime thermal infraredimagery of the entire area. However, due toweather problems, only the first objective was realized.3) Mission 105 was also hampered by weather. Thegoals were photography, infrared spectrometry, multifrequencymicrowave radiometry, SLAR, scatterometry,and thermal infrared imagery of certain regions withmthe test site. The first four were flown, and the first twoof these have been assessed. Instrumented ground stationswere established and manned for the flights. Their primaryfunctions were to provide navigational aid and control,and to monitor ground surface phenomena (contactand' radiometric surface temperatures, temperature-depthprofiles, soil moisture-depth profiles) and micrometeoro-MAY, 1970 • THE MINES MAGAZINEFigure 2, An example of Remoie Sensing (infrared Imagery) compared with aerial photography.

Major drainage lines in mountainous areas aregenerally detectable.Although greatly generaMzed, major topographic features(major ridges, peaks, and valleys) can be readilydetected on the imagery. More subtle features of topographysuch as secondary stream banks, small ridges andsmall scarps (less than 15 feet high) are not easily found;however, the selective growth of vegetation does allowsome subtle features to be located.Many prominent mountain drainages are lost on theimagery where they debouch into the adjacent lowlands.Venus Fly-By radar imagery cannot be used to maphthologic contacts. Even highly contrasting units such asPrecambrian igneous and metamorphic complex and Pennsylvania-Permianredbeds cannot be seen on the imagery.Even bedrock-unconsolidated sediment contacts can onlybe determined with reasonable certainty by the changesin topographic expression between the different rock types.A number of interesting and important geological featurescan be seen on the color infrared photos from Mission105. The color-shifted film, recording reflectance inthe photo infrared as red, emphasizes geologic structuresor changes in lithology. The excellent resolution of thesystem allows the interpreter to distinguish objects assmall as single trees and narrow dirt roads. Drainage patternsare especially emphasized by vigorous vegetationalong water courses and the low reflectivity of water inthe infrared region, which appears dark on the photos.Cultivated fields are readily distinguishable from pasturelandor forests by pattern and color.Geologic structures in the San Luis VaUey show weUon both the color and color infrared photography. Faultsin Pleistocene and/or Holocene valley fill of the San LuisValley were detected and mapped where previously nonehad been delineated, either on USGS air photos or by fieldmapping.Color infrared photography of the San Luis Valley westof the Sangre de Cristo Mountains shows gently curvingfeatures which are the surface expression of faults believedrelated to the formation of the San Luis Valley. Thepattern of these features is not evident in the field, andonly became apparent when viewed from above. The colorinfrared photography aided in locatmg and identifyingthe faults, owing to the emphasis produced by the increasedreflectivity of the vegetation along them in thephoto IR. The scale and resolution of the Mission 105photos have permitted more acctu'ate determination ofthe boundaries of alluvial fans and pediment siu'faces inthis area.Several CSM students and faculty and USGS personnelhave examined the NASA photos taken along the Sangrede Cristos and the Rio Grande rift zone. They report thatthe color and color Infrared photography allow them to(Continued on Page 6)THE MINES MAGAZINE • MAY, 1970 5

—^ l^Jew ^ooi ^op tlie j^aieontoio^ldtBy Harry C. KentMICROPALEONTOLOGISTS and stratigraphers areoverwhelmed by the vast accumulation of literaturedealing with taxonomy and occurrence of fossil foraminifers.At present it is estimated that approximately 30,000species of Foraminiferida have been recognized and describedin the literature, and that the present publicationrate is about one thousand articles per year. Consequently,it is difficult for workers to keep abreast of the literature.Furthermore, workers must have a consistent taxonomicand nomenclatural framework to enable them to makevalid observations and communicate their findings.As micropaleontological techniques become more sophisticated,not only is information added, but criteriafor recognition and delineation of species are changed.Each worker must painfully search the literature to becertain he has accurately traced the history of a speciesname and considered all possible synonyms. Then, asearch must be made to determine geologic and geographicoccurrences of species and all supposed synonyms.In summary, micropaleontologists and stratigraphers arefaced with the problems of voluminous and expanding accumulationsof information coupled with changing concepts,nomenclature, terminology and objectives. Theseproblems led to the formation of the Western InteriorForaminiferal Data Project.Work was begun in July, 1966, and should soon be availablefor public use. This project was initially financedby the Colorado School of Mines Foundation, Inc. and waslater funded by National Science Foundation Project GN-785. Dr. Harry C. Kent is the principal investigator. Foraminiferadata was collected from the systematic paleontologysections of papers pertaining to Cretaceous stratawithin the States of Alaska, Arizona, Colorado, Idaho,Kansas, Minnesota, Montana, Nebraska, New Mexico,North Dakota, Oklahoma, South Dakota, Texas, Utah, andWyoming, as well as the Canadian provinces of Alberta,British Columbia, Manitoba, and Saskatchewan.The data abstracted from the available papers include;1. A general bibliography file of 704 references noted inthe western interior papers, and a sub-file of 172 westerninterior articles of which 112 contained a systematicpaleontology section; this file includes papers publishedup to 1968.2. Primary species information as noted by the individualauthor. This includes plates, figures, page numbers,type specimen and repository.3. Synonymy of the species as noted in each article, aswell as the corresponding reference.4. The stratigraphic and geographic locations as notedin each article. There are over 30,000 items in this filealone.The collected information is filed on magnetic tapefor computer storage and retrieval. From the stored informationit is possible to obtain details related to geographiclocation, the previous work done in the area,species described, locations, and stratigraphic range.Computer programs can be written to obtain the desiredinformation.The information bank is intended to serve as a basisfor more extensive systems of paleontologic informationstorage and retrieval. It is to be hoped that extensive informationsystems will serve the paleontologist and geologistin study and research within the near future. The jobof abstracting data will be tremendous, but the advantageswill be even greater.BonanzaProjecf(Continued from Page 5)easily discriminate between rock types, particularly inPrecambrian terrain and in areas underlain by the complexPennsylvanian-Permian sedimentary rocks. Severalunconformities have been mapped, based on color infraredphotography. It has been estimated that perhaps as muchas 50 per cent of field mapping time could have beeneliminated in several thesis areas covered by the Bonanzadata, had the data been available. From a first appraisal,it appears that for this region in general color photographyserves best to discriminate lithologic units in thePennsylvanian-Permian section, and color infrared photosare most useful for rock differentiation in the Precambrianmetamorphics.CURRICULUM IN GEOLOGIC REMOTE SENSINGProfessors Reeves and Lee combined to teach a graduatelevel course in geologic remote sensing for the firsttime during the fall semester of this year. This two credithourcourse had five students registered. During the presentsemester, the same course was offered as part of theCSM Continuing Education Series, a series of coursestaught in the evening so they are available to professionalpeople worldng in the Denver-Golden area. Enrollment forthis semester consists of 23 registrants (11 professionalpeople) and 10 non-registrants, (including four facultymembers).The geologic remote sensing curriculum has been expandedto include three courses, each of which wUl betaught next academic year, 1970-1971.

Vertical tubes in lower part of section represent fossilized burrows of the decapod crustacean Callionassamojor Say.DURING the past two summers a special field programin the study of modern sediments has been conductedfor gradaute students in the Department of Geology.The program was initiated in order that selectedgroups of students might have the opportunity to observeand study the sedimentary processes and the associatedorganic and inorganic features which are characteristic ofmodern coastal environments. It is hoped that this detailedstudy of modern conditions will provide a firmerfoundation for the interpretation of ancient sediments.In addition to the more academic aspects of basic interpretationof environment of deposition and distributionof sedimentary rocks, thc study of modern sediments andsedimentary processes forms an important base for theexploration geologist. Since the localization of economicaccumulations of petroleum as well as ore minerais raaybe controlled by the nature and distribution of the sedimentaryrocks, it is important for the geologist to understandas well as possible the basic environmental factorsin order to plan an exploration program. The work in thestudy of modern sediments has been pioneered and emphasizedin the United States by many exploration companies,particularly petroleum companies, and the CSM programis designed to provide some of the benefits and insightof such study to graduate students.The logistics of the modern sediments program havenecessitated that the participants be restricted to a smallnumber each summer, and, consequently, six graduatestudents were involved during the summer of 1968 andfour during the summer of 1969. Funds for the operationof the program have come in part from grants made tothe Department of Geology by the Humble Oil EducationFoundation and the Shell Companies Foundation Incorporated.Students participating in the program provide theirown living expenses.In addition to dU'ect fmancial support, contributionshave been made to the program by Chevron Oil Co., TheCalifornia Company Division, in providing discussion leadersand the use of a company plane for an air trip overthe Mississippi delta; Esso Production Research Co.through a visit to its laboratory in Houston; the AgricoDivision of Continental Oil Co, through discussion andvisit to the phosphate-mining area of Florida and by Dr.John Hoyt and Dr. James Howard of the University ofGeorgia Marine Institute at Sapelo Island, Georgia, whohave spent several days in the field with the study groupsand have made available the facilities of the Marine Institutefor our use. Many other organizations and individualshave also contributed to the program through encouragementand providing support in critical areas, includingPan American Petroleum Corp., the Miami Geological Society,and the National Park Service. For the initial twoyears, the program was conducted by Dr. Harry C, Kent.A similar program is planned for the summer of 1970 tobe directed by Dr, Richard H. De Voto.The field study areas of the modern sediments programhave included regions of both detritai and carbonate sedimentation.An introduction to the sequence of depositionof barrier islands has been given at Galveston Island,Texas, where the various subenvironments of shoreface,foreshore, backshore and lagoonal sedimentation havebeen well studied and documented, including the associatedsedimentary structures and biota. This work has beensupplemented by additional study on the barrier islandsequences of Santa Rosa Island and the related sound andbay areas near Pensacola, Florida, in the Appalachicoladelta region of Florida, and at Sapelo Island, Georgia,At each study locality, the physical parameters of environmentalenergy (including waves, wind and tide); temperature,pH, and salinity of the water; observed sedi-MAY, 1970 THE MINES MAGAZINEmentary structures, and assoeiated fauna and flora wererecorded. In addition, ti'enches were dug through beachesand sand dunes and oriented latex peels and photographstaken to record the sedimentary structures. Box coresand other types of cores were made and treated in thelaboratory by plastic impregnation so that they could bepreserved for future study. A number of beach profileswere also measured in order that the nature of the slopeof the beach can be compared between locahties and thata comparison may be made from year to year of thechanges which might occur at any one locality.In addition to the barrier island studies, the cheniercoast of western Louisiana has been examined briefly, andthere have been both ground and aerial survey of the MississippiRiver delta region. Both of these areas havebeen treated briefly in the program because of their complexityand of time limitations, but it is to be hoped thatthe students are able to gain some appreciation of thevariation in environments of deti-ital deposition aiong theGuif coast. Another area of brief study has been theEverglades region of South Florida where emphasis hasbeen placed on the environmental factors controlling thedistribution of different types of plant growth, and thenature of modern swamp and "grass plain" environmentsand their relationship to potential coal formation.Each year, a high point of the program has been thestudy of environments of carbonate deposition in theNow added to our capabilities in mineralogy, metallurgicaland chemical process development.—Plan, organize, and conduct geochemical surveys to supplementyour geological and geophysical exploration programs.—Aid with data reduction, trend analyses, interpretation.J.

JOSEPH LEAD CB., 250 Park Auenue, New York, New York 10017SINCE 1960, the geology summerfield course has invoived a mobileprogram throughout central and westernColorado. Prior to that time, semipermanentfacilities were used duringthe entire six weeks of the course,and relatively short trips away fi'omthe central location provided somedegree of variety in geologic settingsand problems. Best known amongthese facilities is the camp at Wildhorse,north of Pueblo, where manyhundreds of CSM alumni receivedtheir fu-st professional training infield geology.Because of the significant advancesin highways and highway vehicles, amobile camp is more feasible nowthan in earlier decades. It seems onlylogical, therefore, that the departmentwould eventually take advantage ofthe spectacular examples of fundamentalgeological fieid relations sowonderfully exposed throughout theColorado portion of the SouthernRocky Moimtains,The philosophy behind the fieldcourse is to provide students withtraining, experience, and competencein a variety of geological situations.This philosophy is actually the basisfor establishing the mobile aspect ofthe course; specific areas have beenselected to illustrate principles, processesand pi'oblems relating tostratigraphy and sedimentation, structuraland tectonic geology, plutonicigneous and metamorphic geology,volcanology, geomorphology, and theapplication of the above to the fieldsof petroleum, mining and engineeringgeology. Field ti'ips between areasand lectiu-es in camp emphasize theregional relations of local areas inan effort to bring together a comprehensiveimderstanding and appreciationfor the geologic history of a largeportion of the Rocky Mountains.During the past decade, the staffhas researched numerous localitiesand has used them on various occasionsfor one-week problems.

Technological improvementshave been made throughout thehistory of the petroleum industry andundoubtedly wiU continue to be made—these have been offset to a large extentby rising costs of materials, labor,and taxes,Several recent studies by the NationalPetroleum Council and the U. S.Department of Interior's Office of Oiland Gas have reviewed various aspectsof new technology in oil and gasexploration, driUing and recovery, productivecapacity, cost reduction,transportation, and oil refining. Importantaspects of technological advancesthat affect the petroleum industryare summarized below.EXPLORATIONNo major breakthrough in impi'ovementof exploration methods has beenmade in recent years and none is anticipated;gradual improvements arebeing made constantly. Improved geophysicalmethods have made possiblethe discovery of deeper structuraltraps, but there has been little improvementin ability to find stratigraphictraps in sandstones by the useof geophysics. A trend toward deeperdriUing has developed in recent yearsand this wUl continue.Knowledge of depositional environmentsand geochemistry of modern^Professor of Geology,School of Mines.ColoradoBy John D,Hatm'sediments has increased markedlyand this knowledge has been used ininterpretation of ancient environmentsand in evaluating oU and gas potential.With subsurface information, itis possible to reconstruct geographicfeatures as they existed in the geologicpast. There is continuing improvementin these techniques and they offerthe most promising methods forfutm'e exploration. An increase indriUing activity wiU increase the rateat which subsurface geologic techniquesmay be applied. Methods ofcomputer processing, analysis andsimulation are increasing the efficiencyof data usage.Increased study of pressure, temperature,and fluid movements in reservoirrocks also should lead to amodest increase in exploration efficiency.New tools and well-loggingmethods, and improvements in presentmethods, should increase the abilityto interpret subsurface conditions.Development of a direct above-groundoil-finding technique does not seem tobe a reasonable expectation. Most explorationis the result of the controlledimagination of the petroleum geologistor geophysicist —• his education andworking conditions are as importantas new developments in explorationhardware.DRILLING AND RECOVERYA major part of exploration and developmentexpense is aUocated todriUing and completing weUs. Changesin driUing — rig design and drUlingmethods have reduced time and expenseof drUling some holes, Costs ofdrilling deep weUs have been reduced,but costs of intermediate-depth wellshave remained relatively constant.U.S.G.S.

Mostinjection projects use water and/orgas, but much progress is being madein the use of solvents (miscible-a genttechniques), steam injection, and insitu combustion (fireflooding).It is common practice to increaseoU and gas production by explosive orhydrauUc fracturing. More extensivefracturing is possible through the useof nuclear explosives. Project Gasbuggyin New Mexico, Project Rulisonin Colorado, and other nuclearfracturing experiments to be conductedin Colorado and Wyoming,should determine the practicaUty ofthis technique in increasing the ultimaterecovery of gas.If these experiments are successful,it is estimated that an additional 200trillion cubic feet of gas should be recoverablein the Green River basin!Recovery of oU or gas from oil shaleand coal by the use of nuclear stimulation,and conjunction with othertechniques, is in the planning stage andcannot be evaluated at present.

He did his undergraduatework at Rensselaer Polytechnic Institute,then at Louisiana State University, where he received hisB.S. and M.S. degrees in Geology. His Ph.D. work was atStanford University, emphasizing Remote Sensing andComputer Apphcations in Geology. Expansion of the RemoteSensing Program here at Mines is one of the mainreasons for his presence. Dr. Lee's interest in RemoteSensing sometimes takes unusual turns: he is currentlythinking about research into snakes' remarkable heat sensingabilities, using his pet rattler for a data source.Dr. Grybeck received his B.S. degree from the Universityof Alaska in 1963, where he worked as a research assistantin theii- Geophysical Institute. He bypassed theMaster's program and received his D.Sc. from ColoradoSchool of Mines in 1969, doing thesis work on lead, zinc,and silver ores and minerals in Colorado. He has workedfor the last two summers in Alaska for the U.S.G.S., andliked it so much that he has decided to return to the Universityof Alaska next fall as a Professor. During hisyear as Professor at Mines, he taught Ore Microscopy,Structm-al Geology, and Stratigraphy.Dr. Rogert Reeves, who last year was an adjunct professorin the department, accepted a full ProfessorshipNovember 1, 1969,Communications Gap Bridgecbetween Students and FacultyIHIS year, under the direction of Dr, Harry Kent, actinghead of the CSM Geology Department, a committeeconsisting of three elected graduate students andDr, Kent has been estabUshed to provide a communicationsUnk between the graduate students and the departmentfaculty.

HOUSSELS, Sr., Chairman of the BoardCLASS OF '22)onations Accepted HereMINERAL specimens of exceptional quaUty are extremelyrare and difficult to obtain—especiaUy if amuseum operates on a limited budget as we do. Manyclassic localities of the world have been depleted of theirgood-quaUty material and specimens must be eitherpm'chase or traded, at often exorbitant prices. The newlocaUties which have opened up in recent years are, inmost cases, the property of mining companies whichfrown on slowing down their operations to look for individualmineral specimens, no matter how weU crystallizedor unusual they might be. Of course, rarity causedby these situations only helps to up the price of those fewspecimens coUectors are able to obtain.Fortunately, many minerals more easUy obtained nowmay turn into the "classics" of the future, when then' localitiesare depleated. The Museum is fortunate to havehad good guidance over the years in acquiring many fineexamples of this type. And, although not frequentlyenough, we have been able to trade for some of the morerare classics. However, the coEection is always tn need ofimprovement and adidtions. There's nothing more frustratingthan having a visitor—alumnus, student, or privatecoUector—-who insists on reminding us that our specimensfrom his home state or a locality he's famiUar with arenot really the best obtainable, and then not offer to doanything about it!Museums of all types are having financial and collectingtroubles at present, but Mines least of aU should be,due to the nature of most alumni and friends. Many stiUhave direct access to minerals through their occupationswith mining and exploration companies. Others havefine collections which they began as students here atMines. We would like to offer om- fine display facilities toanyone interested in helping the Geology Museum.

^awdonite andCjiLLditWEbelieve that the Geology Museum plays au importantpart in the public relations of the School ofMines. After all, it is probably the first—and many timesthe only—part of the School that most visitors see. Therefore,the Museum should be the best and most active onethat we can possibly produce and operate effectively,After getting such a good start on a fine collectionunder the able direction of Dr. J. Harlan Johnson, theMuseum was dormant from 1957 until Miss Jerri Hamiltonbecame Curator in 1965, In addition to giving the collectionsmuch-needed attention and upgrading the exhibitquality, she carried out a very active public relations programin the form of tours organized for Jeffco school childrenand any otiier interest groups.Tills program is being continued now, and seems tobe expanding at a rewarding pace. Even if the Museumserved no other purpose—which is far from the case—-itwould be worthwhile. Actually many different groups benefitfrom its presence: students, faculty, new student recruiters,and the general public. If we can aid in showingprospective students and other visitors that Mines is progressiveand responsible in its educational role, then wewill have done om* job.The methods available to the Museum for meeting theseneeds are meaningful exhibits, information sent to inquii'ers,and educational material which visitors can takewith them. Accordingly, a stepped-up program of new exhibitsand publications has been undertaken. Ironicallyenough, although the Museum is called a Geology Museum,tliere were no exhibits of a general geology nature includedin its plan. Now, a small section has been designatedfor this pm'pose, and is about half completed. Theoutstanding exhibit here will be about the geological formationsof the Golden area, complete with cross sectioni n e r al|N MARCH 26, two Geology Department staff membersand ten students left for New Mexico on a field tripto the Santa Rita and Tyrone mining districts. While inNew Mexico, the students were required to complete detailedmapping problems in the Chino Pit area, in an areaacross the southern end of the Fierro stock, and undergroundat the Jersey Zinc mines at Hanover, About oneday was spent examining the alteration and mineralizationin the vicinity of the new Phelps-Dodge operations at Tyrone.Throughout their stay in New Mexico, the group workedclosely with the resident personnel of the Kennecott, NewJersey Zinc, and Phelps-Dodge Corporations, The readycooperation that these companies extended was in largepart responsible for the success of the field trip,16model and reconstructions of the area's geological history.Another section in the Museum has been assigned to economicminerals and Colorado mining history. This willinclude some nostalgia about early mining camps as "atmosphere,"although the ores and minerals which madethem important wiU of course be the main attraction,rilHE outstanding mmerals collection still occupies mostJL of the Museum's main gallery, with the addition ofsome educational exhibits about the natm'e of minerals:their physical properties, important localities, special featuressuch as fluorescence, and gem-forming minerals.Each new addition to the collection is extremely welcome,and is first placed on display in the recent acquisitionscase, from whence it is circulated to other pertinent exhibits.Because of its smaller size, the fossils collection showsmore of a vast improvement, since we were able to entirelyrearrange it, A student assistant has now begun thetask of drawing restorations of principal life forms andexplaining each geologic period, so visitors can understandmore of this aspect of geology.Many visitors inquire as to literature about the Museumand its collections which they might read to learn moreabout what they have seen. Until now, we have had toteU them that there was nothing available. Within the nextfew weeks, we will have printed a pamphlet about theMuseum and its collections, to be followed by two otherson related subjects. We hope that these initial efforts willlead to such things as a small collection of coior photosof outstanding specimens in the Museum, eventually buildingup a group of informative booklets on many differentaspects of geology, especially as it relates to our region.We would like to invite anyone interested to come andsee the new face of the Geology Museum, We think you'llapprove!The value of a field trip devoted to the detailed examinationof mineral deposits has long been recognized bythe Geology Department as an important addition to thetraining of CSM economic geologists. Unfortunately, duringrecent years, funding was not available for such a program.In September, 1969, Mr. Arthm- Meyer, representingthe Union Pacific Railroad Company, established athree-year grant to be used for the instruction of Geologystudents in the field at important mining locations. Thisyear it was decided to study the Central Mining Districtof New Mexico,In planning the program of study. Dr. R.

Bloom-ifTIHICKand geographically wide-X spread mutual occurrences of theminerals dawsonite, NaAl(OH)2C03,and gibbsite, Al{OH)a, exist in thekerogen-bearing dolomites (impreciselytermed "oU-shales") of the GreenRiver Formation of the PiceanceCreek Basin, northwestern Coiorado(Figure 1). The gibbsite and dawsoniteoccupy an interval with a thicknessgreater than 50 feet and an aluminumcontent greater than 1.5 percent over approximately 500 squaremiles. The aluminum-bearing mineralsoccur through as much as 750feet of kerogen-bearing dolomite, whichaverages 25 gallons of oil per ton.Locally in the section, the dawsonite(and gibbsite) comprise up to 25 percent by weight of the "oU-shale"(Smith and Milton, 1966, p. 1029). Thisthick, widespread deposit has createdmuch interest in the gibbsite and dawsoniteof the Green River Formationas a potential ore of aluminum.Discovery.—Dawsonite was first discoveredin the Green River Formationin 1959 and described by Milton andEugster (p. 124) in their comprehensiveanalysis of the saline "MineralAssemblages of the Green River Formation."Quantitative analysis of thedawsonite content in two deep driUholes were published by Smith in 1963(p. 811). Smith's paper indicated forthe first time the great thickness andhigh concentrations of dawsonite inthe "oU shales" of the deep part ofthe basin. In 1964-1965 several coreholes were drUled to explore for sodiumand thereafter to evaluate thenahcollte (NaHCOj) deposits locatedwithin the "oil-shales." The presenceof considerable concentrations of dawsonitein strata up to 700 feet thickover a substantial area were discoveredby these exploratory holes.The occurrence of gibbsite ubiquitouslywith dawsonite was originaUysuggested by the fact that in manyunits there is considerably more dilute-acid-solublealuminum than sodium.Smith and Johnson (1967) firstsuggested the presence of the mineralgibbsite after carrying out chemicaldeterminations and differential ther-* Geology Department, Colorado School ofMines.tEarth Sciences, Inc., Golden, Colorado.mai analyses. Chemical and differentialthermal analyses of outcrop samplesand samples from oU-well holeshave confirmed the widespread associationof gibbsite and dawsonite inthe Green River Formation of thePiceance Creek Basin,Stratigraphy. — Stratigraphic relationshipsof the Eocene rocks of thePiceance Creek Basin are summarizedon the structural cross section {Figure2) and the detailed transbasinalstratigraphic cross sections (Figures3 and 4),Varicolored shales, mudstones, andsandstones of the aUuvial WasatchFormation accumulated in the earlyEocene and underUe the Green RiverFormation throughout the PiceanceCreek Basin.

(TOSCO), 4 claims.The relinquishment is seen by Interioras a major stepping stone toclearing away a complex maze oflegal matters which have in largepart hobbled oil shale development.Loesch said he's confident otherclaimants wiU realize, their dawsoniteclaims are invalid and foUow the exampleset by the major firms,"When this complication is clearedaway, we can get on rapidly with developingan oil-shale program toserve national needs," Loesch said.But Interior and its agency handUngoU-shale matters, the U.S. Bureauof Land Management, has a longway to go.Not aU of the 26,536 acres of reUnquishedclaims has been cleared legallyfor others claim them too, AlLeonard, coordinator in Denver ofBLM efforts to clear title to oil-shalelands, said.He said 4,235 additional dawsoniteclaims have yet to be cleared in KioBlanco County and others remain inother northwest Colorado counties.Interior contends the mining claimsare invalid because they come underthe mineral leasmg act of 1920 andnot the 1872 mining law,Dawsonite, an aluminum-bearingmineral, was discovered in 1966 in thearea and for several months manyclaims were filed under the freewheeling1872 mining law that permitsminerals on pubUc lands to beexploited.Interior moved to stop this becauseof its clouding of oil-shale claims.Dawsonite and nacolite ores are foundin conjunction with oU shale.The relinquished claims don't includeoil-shale placer claims locatedprior to the Mineral Leasing Act in1920, Loesch said.Many of those oil-shale claims arenow before the U.S, Supreme Courtwhere Interior is trying to gain leasingrights after losing earUer legalrounds in the dispute,BLM is involved in a long-termsearch of county records to clear uptitle matters involving oil-shale lands.The search and processing is expectedto take years.

Consequently the characteristiclithologies of the GreenRiver Formation are well laminated,lacustrine mudstone, shale, marlstone,and dolomite. The Green River Formationcan be subdivided on thebases of sandstone content and presenceor absence of substantial quantitiesof kerogen into five mappablemembers (from oldest to youngest): Douglas Creek, Anvil Points,Garden Gulch, Parachute Creek, andEvacuation Creek (Donnell, 1961) (seeFigure 2).The Douglas Creek and Anvil PointsMembers are dominated by brownto buff, cross-bedded, ripple-markedsandstone, algal and ooUtic limestone,and gray shale, which is barren ofkerogen. These beds accumulated ator near the shore of the newly formedEocene lake in the high energy environmentsof the delta, shoreline, andalluvial plain. The Douglas Creek andAnvil Points Members thin abruptlybasinward by facies change to thewell laminated shales and kerogenousmarlstones of the Garden Gulch andParachute Creek Members.The Garden Gulch Member is composeddominantly of well laminatedshale which is barren of kerogen.Locally marlstones, thin sandstonebeds, and limestones occur in theMember. The principal difference betweenthe Garden Gulch Member andthe overlying Parachute Creek Memberis the relative lack of kerogen andcarbonate in the Garden Gulch. Locallyin the center of the basin, theGarden Gulch Member does containsignificant concentrations of kerogen.Figures 3 and 4 display the facies relationshipsof the Garden Gulch withthe overlying Parachute Creek andunderlying Anvil Points and DouglasCreek. The shoreward divergence ofthe bedding planes and time lineswithin the Garden Gulch Membershows that a greater thickness ofallogenic lacustrine mud was accumulatingnear the shore than in thecenter of the lake during the sametime.The Parachute Creek Member containsthe gibbsite, dawsonite, nahcoiite,halite and the thickest and richestkerogen-bearing beds in the GreenFUver Formation, The Member iscomposed almost entirely of dolomiteand marlstone, most of which yieldoil when distilled. The thickness andoil yield grade of the kerogen-richdolomite increases greatly toward thecenter of the basin from all sides, asshown on Figures 3, 4, and 5 (Stanfield,1966, p. 36). The coincidence ofthe present structural low of the basinand the thickest area of rich "oilshale" shows that chemical stratificationof the lake must have controlledthe preservation of the organicmaterial on the lake bottom. Thus,the relatively clear and fresh surfacewater supported a prolific flora, whilethe bottom conditions beyond a criticaldepth were reducing and saline, favorablefor the preservation of the organicdebris. Figures 3 and 4 showthat the basal 1000 feet of kerogenbearingdolomite accumulated in thecenter of the basin while kerogenleanmarlstones were deposited nearerthe edges of the lake. The gibbsite,dawsonite, nahcolite and halite areconcentrated in this same interval.The gibbsite and dawsonite are concentratedin a stratigraphic intervalbetween 400 and 1400 feet below theA-groove marker bed (Figures 3and 4) in the center of the basinwithin the richest "oil-shale" units.The shoreward convergence of thebedding planes and time lines withinthe Parachute Creek beds below theA-groove marker bed illustrates thatthe chemical-density stratification ofthe lake allowed a greater thicknessof kerogen-rich dolomite to accumulatein the deep central part of thedepositional basin than near the edgesduring contemporaneous deposition.This same chemical-density stratificationallowed the preservation of agreater concentration of organic debrisand was probably a factor contributingto the formation of the gibbsite,dawsonite, and nahcolite. The conditionswhich allowed the preservationof the organic debris became morewidespread with the passage of time,permitting the accumulation of thebasinwide kerogen-rich Mahogonyzone ("a Mahogony Ledge") near thetop of the Parachute Creek Member.The A-groove marker bed is a widespread,thin, relatively kerogen-lean,tuffaceous dolomite bed which can beused effectively as an electric-logmarker for correlation purposes.Hence, the stratigraphic sections (Figures3 and 4) are hung on this marker.The upper 800 feet of the ParachuteCreek Member contains dawsonite,gibbsite, and nahcolite in significantquantities, although it is much moreirregularly distributed than in thelower portion.The Evacuation Creek Member iscomposed of buff to brown, lenticularsandstones, siltstones, kerogen-leanmarlstones, and shales, which accumulatedin the waning stages of thelacustrine deposition. Thus, the Memberincluded interbedded facies resultingfrom varying depositional environments: lacustrine (laminatedmarlstones and shales), shoreline,deltaic, and alluvial (standstones, siltstones,and nonlaminated shales). Thegradual restriction of the lake causedthe contact between the ParachuteCreek and the overlying EvacuationCreek Members to be gradational anda facies relationship. Hence, kerogenbearingmarlstone deposition persistedin the much-restricted lake in thebasin center long after non-lacustrineconditions overtook the rest of thebasin.Dawsonite and Gibbsite.—The distributiotiof significant concentration18 MAY, 1970 • THE MINES MAGAZINETHE MINES MAGAZINE • MAY, 1970 19

A500-foot-thick continuous interval averaginggreater than 1.5 per cent aluminum(and an average of 25-35 gallonsof oil per ton) extends over approximately250 square miles, beingconfined essentially to a northwestsoutheast-trendingarea which conformsroughly to the present basinalaxis.

The original discoveryof the dawsonite in the Green RiverFormation by Milton and Eugster(1959, p. 124) and the later more detailedquantitative evaluations performedby Smith (1963, p. 811), andSmith and Milton (1966, pp. 1034-1035),were made with X-ray diffractiontechniques.

Total Thickness of Intervals Averaiging 2.8%Soluble Aluminum (Dawsonite St Gibbsite), Piceance CreakBasin, Colorado.In the quest for rapid, inexpensive,quantitative, analytical tests for dawsonite,various chemical techniqueswere tried. It was found that bymaintaining careful control of Ph andleaching time, a 30 per cent hydrochloricacid solution would dissolvedawsonite and gibbsite and would notappreciably attack the aluminum silicates,i.e., various zeolites, clay minerals,and feldspars. The percentageof aluminum in a sample was thendetermined by simple colorimetricmethods. This inexpensive quantitativetechnique enabled rapid evaluationof thick sequences of the GreenRiver Formation from gas-well, rotary,drill-hole cuttings from throughoutthe basin.The chemical analyses indicate thatanother a cid-extr actable aluminumbearingmineral occurs within the "oilshales" along with dawsonite. Solublesodium analyses were performed withsodium-ion electrodes and checked byflame photometry. Virtually all samplesanalyzed for soluble aluminumcontain less sodium than that necessaryto combine with the aluminum toform dawsonite, NaAl(0H)2C03. Theratio of the other acid-extractable aluminum-bearingmineral to dawsonite,as determined by chemical analyses,ranges from 4/1 to 1/4.Differential thermal analyses, asoriginally performed and suggested bySmith and Johnson (1967), illustratethat the other soluble aluminum-bearingmineral displays an endotherm20-30°C below the temperature of thedawsonite endotherm (Figure 7). Thisother aluminum-bearing mineral alsodisplays a broad endotherm at 540-580°C. The differential thermal analysisresults indicate that dawsonite andthe other soluble aluminum-bearingmineral occur as distinct mineralogicalentities.Smith and Johnson note that thenon-dawsonite aluminum-bearing mineral(1) is readily solubie^in acid, (2)contains no sodium, (3) degrades thermallyin two steps, one at 330-350°C,and another at 540-580°C, (4) is notdetectable by X-ray diffraction, and(5) occurs in kerogen-rich dolomite("oil shale") with dawsonite. Theyalso note that gibbsite, A1(0H)3, adsorbedon clays or organic materialor too finely particulate to be detectedby X-ray diffraction or optical techniques,has all of these characteristics.Differential thermal analysis of chemicallypure gibbsite displays a twostepthermal degradation similar inall respects to that of the aluminumbearingnatural mineral, except for aslight endotherm shift due probablyto the occurrence of tiie natural compoundin the "oil shale" matrix. Thetwo endotherms are probably the resultof release of water from the gibbsitein partial steps.Several photomicrographs whieh illustratethe various habits of dawsonitein the Green River Formation haverecently been published by Smith andMilton (1966, pp. 1030-1035). Much ofthe dawsonite is disseminated as 0.05to 0.2 mm (65 to 250 Tyler mesh)particles throughout the kerogen-bearingdolomite.

The gross value, in place,of the kerogen contained in this samezone (averaging 25 gallons of oil perton) is approximately $1.75 per ton.The ultimate value of this rock coiddbe controlled more by its value asaiuminum ore than by its value ag asource of oil. Every square mile (ofthe 250 square miles) that has a 500-foot thickness of continuous intervalaveraging 1.5 per cent aluminum containsbetween % and 1 billion tons ofpotential ore. Final economic evaluationof the net value of this materialclearly depends upon extraction andrefining costs.The gibbsite and dawsonite of theGreen River Formation of the PiceanceCreek Basin represent a tremendousdomestic resource as a potentialsource of aluminum. The UnitedStates presently imports over 10 milliontons of bauxite ore annuaUy (86per cent of its needs).

In the letterwas an assurance that changes atMINES would be "responsible." This,I hope, may always be true. Anyway,I took a year's subscription, partlyas a matter of loyal support butchiefly to know more about eventsthere,A letter from Mr. Jack L, Rivkin,pubUshed in the Mar. 17, 1970 issueof the OREDIGGER strikes me asbeing an unfortunate emotional displayof personal feelings' quite oppositeto my own, I think you deservea lot of credit for "keeping your cool"in the face of very trying circumstances.It seems to me that thewhole Alumni Association owes youa debt of gratitude for getting out areputable magazme that is a creditto the school and the industry, If Mr,Rivkin wants to follow aU of thepetty bickerings within the schoolhe might subscribe to the OREDIG­GER. as I have done. That sort ofmud-slinging may be more appropriatethere than in the MINES MAGA­ZINE,Very sincerely yours,SIDNEY W. FRENCHSidney W. French, Met. E. 1908Robert McMillan, '41E. J.

Fkday, Corinthian Editions,New York, $12.50, 356 pages.No metal has served mankind sowell, for so long, and in so many essentialways. Copper, containingtraces of silver, was man's first engineeringmetal, the first malleablematerial he coidd hammer into toolsand weapons to provide fhe first giantstride toward civilization.Silver-bearing copper looks and actslike copper in most respects. But 12to 25 ounces of silver in a ton ofcopper give copper the highest combinationof conductivity and strengthin its service temperature range ofany material. Silver-bearing copperalso has significant advantages overordinary copper in such characteristicsas oxidation, wearand resistance to creep.resistance,Hundreds of facts about silver-bearingcopper have been compiled byDr. Finlay, Director of Research forCopper Range Co., in the new book,which will be primarily helpful tothose responsible for designing,specifying, fabricating and processingspe cial-property copper metals. Theseare designers, manufacturers, students,and engineers.The book dehneates the propertiesand characteristics of copper andsilver-bearing copper, its applicationsthrough the centuries, and its greatstability and versatility which enableit to meet and answer demandsof constantly changing sets of requirements.The book is designed by S. NeilFujita and written in an easy-tounderstandmanner. Its highlights include:1. The in and outs of the oldest professionin the world—the mining andmetallurgical utiUzation of silverhearingcopper. Nature started theoperation i.i billion years ago atwhat is now White Pine, Mich, on thesouthern shores of Lake Superior.This bUIion-year-old m&tal is callednative copper to distinguish it fromman-produced copper.2. First metallurgists in ttte WesternHemisphere were the Old CopperIndians, of 3,000-5,000 B.C. On theback cover of Silver-Bearing Copperis a life-sized color photo of nativesilver, as formed by Nature a biilionyears ago on a piece of native copper.As noted on the inside backcover, this unique piece suggests anOld Copper Indian head in profile.Prof. Earl Parker, Met.E. 1935 ofthe University of Caiifomia and presidentof the American Society ofMetals m 1967-68, said (page III);"Only one atom of silver to five thousandatoms of copper can producethis great change in properties!''These great advantages are highercreep and stress-mpture strength' Dr. Walter L. Finlay(page HI and Chapter IV); highestcombination of conductivity andstrength in its service temperaturerange of any material (page VII andChapter 110); higher resistance toheat softening (Chapter 111); andhigher oxidation resistance (circle onfront cover described in front endpapers).3. Man requires about 0.0002 percent of his body weight as copper inorder to live: oysters have morecopper than any other food whichmay be suggestive; and there arethose who believe copper absorbed bythe body wards off arthritis (page 3,appendix I).4. Compared to copper's healthyruddy color, gold is a pallid yellow,titanium, a blackish-white, silver,aluminum and aU the other metals ableached-out white. To what doescopper owe its unique red Color?Why is copper black in green light,and green by transmitted whitelight (Appendix H).5. Copper made civilization possible(pages 3-5) and silver-bearingcopper helps to sustain an advancedcivilization by being the best materialfor such apphcations as: Electriccommutators and rotor winding(Chapter XI); Auto radiator fms(Chapter X); Busbars (Chapter XH);Photoengraving plates (Chapter XV);Infemo facers (Chapter XIV).The purest ore available, WhitePine's silver-bearing copper is the resultof a complex metallurgical extractionprocess that was done in agigantic geologic classifllc ation operationa billion or more years ago. Oneof three metals provided by Naturein the metallic state, copper gavebirth to the art of smelting metalsfrom their ores.Silver-bearing copper is extracted,milled, and refined in the White Pine,Michigan installation of CopperRange. It occurs naturally in Michigan'sremote Upper Peninsula as partof a vast table-shaped orebody whichcover hundreds of square miles andalready assures adequate reservesfor 50 years of mining. It is said tocontain ahout 15 per cent of knownU. S. copper reserves.Dr. Finlay, director of research forCopper Range Company, is a graduateof Lehigh and Yale Universities.He has had wide experience in bothnonferrous and ferrous metals, andhas several dozen patients involvingcopper, aluminum, lead, titanium,and steel developments. A chartermember of the Titanium Founders Society,he holds more than a dozentitanium alloy patents, covering mosttitanium alloys currently in productionthroughout the world.While Director of Research forCrucible Steel Co. of America, Dr.Finlay was awarded the AmericanIron and Steel Institute's Elbert H.Gary Medal for a paper on thevacuum degassing of high perfor--mance alloy steels.Technical Societies ALASKA TECTONIC SYMPOSIUM7970 Wesfern ResourcesConference July 8-10Af Denver UniversityTHE1970 Western Resources Conferencewill be held at the Universityof Denver on July 8, 9, and 10.The Conference theme will be "UrbanDemands on Natural Resources."The effect of urbanization on theuse and development of our naturalresources will be considered underfive topics—Air, Water, Raw Materials,Land, and Choices. Over 20speakers from the Rocky Moimtainregion and other parts of the UnitedStates win appear in the five sessions.This is the twelfth in a series ofconferences that began in 1959, TheUniversity of Colorado, Colorado StateUniversity, Colorado School of Mines,and the University of Denver aremembers of the inter-university groupthat sponsors the conference series.John J. Schanz, Jr., professor ofnatural resources and a member ofthe Denver Research Institute's IndustrialEconomics Division, hasbeen named general chairman for the1970 conference.Mullins Named ChairmanOf NCPC; Warns EnergyShortage PossibleT. C. Mullins, president of PeabodyCoal Co. of St. Louis, one of theworld's major coal-producing companies,has been elected chairman ofthe National Coal Policy Conference,Inc., a Washington-based organizationwhich represents all segments ofAmerican industrial hfe engaged inthe production, transportation andutihzation of bituminous coal.Mr. Mullins succeeded W. A, Boyle,president of the United Mine Workersof America, who has served as chairmanof the organization for the pastthree years, the longest tenure in thehistory of the 11-year-old group.Mr. Mullins, who is out of the countryon business, warned in a statementwhich was read for him at themeeting by Peabody Vice PresidentHugh B. Lee, that "this Nation is onthe verge of moving from an era ofenergy sufficiency to one of energyshortage" and that some governmentofficials, in an effort to meet thischanged condition, are attemping "todowngrade domestic energy fuels—oil, natural gas and coal—and to seeksufficiency through greater relianceupon imported fuel."Such an answer to "a serious nationalproblem, is fraught with graveimplications for national security andfor the national weKare and must herejected," he declared.rilHE second Alaska Tectonic Sym-X posium, organized by tlie AlaskaGeological Society in cooperation withAlaska Methodist University, recentlybrought together some of the world'smost eminent earth scientists to discussAlaska and its relation to globaltectonic pattems and continental drifting.These new concepts are especiallyimportant now that Alaska hasbecome a focal point for explwationand research by geologists and geophysicists.Dr. J. Tuzo Wilson, professor ofGeophysics at the University of Toronto,discussed the life cycle of oceanbasins with particular reference' to theArctic. He applied the concept ofspreading outward from oceanicridges to the rifting and fracturing ofcontinents and the development ofocean basins.Dr. Michael Churkin, Jr., USGS,Alaska Branch, discussed the correlationof fold belts between Alaska andSiberia and their relation to continentaldrift. CordiUeran fold belts apparentlycorrelate well with belts inthe Kamchatka and Chukotsk Peninsulas.Evidence thus far suggests nodrifting between the Siberian Platformand Alaska. The VerkhoyanskiyMountains, west of the Chukotsk Peninsulaprobably represents the borderbetween North America andAsian blocks. Spreading of the CanadaBasin along an older rift system isspeculative, Churkin suggested thatGeophysical TrainingProgram in WisconsinF^IVE sessions of the Soiltest, Inc.geophysical training program atBaraboo, Wis., have been announcedfor the 1970 season.Subjects covered at the sessions includethe use and application of seismicand resistivity apparatus plusother related equipment used in subsurfaceexploration and investigation.The objective of these sessions is toprovide training in shallow depth subsurfaceexploration for engineers, geologists,government personnel, contractors,and students.All ti-aining facilities are at Soiltest's600 acre Provmg Ground andTraining Center located just outsideBaraboo, Wis., in the geologically-significant"driftless area." The widevariation in the subsurface conditionsof this area makes it ideal for suchtraining.Classes begin on Thursday morningand run through noon on Saturday.Sessions start on May 21, June 18,Sept. 17, Oct, 8 and Oct. 29.Complete information on the geophysicaltraining sessions is availablefrom Soiltest, Inc., 2205 Lee St,, Evanston,111, 60202.source material for the Paleozoic geosynclinerimming the Arctic Basinwas derived from a marginal orogenicbelt that bordered the continents. Wilsonproposed the source was the Asiancontinent prior to drifting.Robert Stonely, British PetroleumCo., discussed the "New Global Teetonics"as reflected in the stmctureof parts of Alaska. The Yakatagaarea shows tectonic patterns typicallyassociated with the underthrusting ofthe oceanic cmst at a continental margin.This underthrasting results in upliftwith overthrusting of shelf sedimentsoceanward.Dr. H. W. Menard of the ScrippsInstitute of Oceanography has recentlydone work in the North PacificBasin which promises to be of majorimportance ih understanding Alaskantectonics.John Moody, senior vice presidentof Mobil OU Corp,, discussed thegeometry of wrench fault tectonics.He believed that there is a worldwidedistribution of maximum stressdirections either east-west or northsouth.His views are, as Menard putit, in "mortal confiict" with plate tectonicsand continental drift.Infrared SensingExperiment ResultsNow Being ExhibitedBENDIX Aero Space Systems ofAnn Arbor, Mich., and HeinrichsGeoexploration Co. of Tucson, Ariz.,are currently exhibiting results of acomprehensive airborne infrared sensingexperiment over the Lone StarMining District near Safford, Ariz.The new results were shown to thepublic at the Washrngton Hilton Hotelat the annual meeting of the AmericanSociety of Photogrammetry March1-5.The imagery obtained further refinesthe available information ontechniques and applicability of theinfrared method for regional mineralexploration.Bendix Aero Space is among theleaders in avionics remote sensing instrumentation.Heinrichs GeoexplorationCo. is an internationally knownconsulting and contracting explorationfirm active in minerals search.The Lone Star Mining District is thesite of a proposed underground nucleartest to be conducted by theAtomic Energy Commission and KennecottCopper Corp,Imagery may be viewed by priorarrangement at headquarters officesof GEOEX in Tucson and Sydney,AustraUa, and Bendix in Ann Arbor,Mich., and vidll shortly be publishedas a scientific paper.

J.S. Uranium IndustrySets Drilling RecorcSurface exploration and developmentdrilling by the U. S. uraniummining industry in calendar year 1969totaled a record 29,900,000 feet, theGrand Jimction, Colorado, Office ofthe U. S. Atomic Energy Commissionannounced today.The 1969 drilling figure was 25 percentgreater than the 23,800,000 feetdriUed by the industry in 1968, theprevious high year, and almost triplethe 10,800,000 feet driEed m 1967. The1969 record represents 21 percent ofthe total 140,000,000 feet of surfacedrilling for uranium since 1948 whenthe AEC began to record industrydrilling figures.At the end of 1969, estimated U.S.uranium ore reserves were 97 miiiiontons with an average grade of 0.21percent U.,Os. These reserves contain204,000 tons of UiO, recoverable at $8per pound of U,Os or less. This compareswith 161,000 tons a year earlierand shows a gain of 43,000 tons during1969.New reserves developed in 1969 contamedan estimated 56,000 tons ofU:,OB. After adjustment for ore minedand shipped to mills, there was a netincrease in reserves diu-hig 1969 of43,000 tons of U,,0s. This increase isthe greatest of any year since 1957.As one stows away the snow shovelat the end of the season, the joy issomewhat diluted by what appears tobe a fiendish metaUic chuckle whichcomes from the lawn mower standingbeside the implement rack.40Earlougher EngineeringR.

Part of the increase was due togreater production and higher pricesof lead, molybdenum, vanadium, andzinc.Florida, $301.9 million, a decreaseof 1 per cent below 1968. The overalldecline in value of mineral productionis attributed to slow phosphate salesand lower prices. Nonmetals accountedfor 94 per cent of the state'stotal mineral production value.Georgia, $201 miihon, an increaseof 16 per cent over the previous recordvalue in 1968.
