ORGANIZATION UNIT OF THE VICE-DIRECTOR FOR GEOLOGY * GEOLOGICAL DIVISIONRTG mapa spineluelectronic form. The labor<strong>at</strong>ory provides also carbon samplesevapor<strong>at</strong>ion.During the year 2007 in the scope of the internal tasks theDepartment advanced also in methodical procedures in thefollowing areas:– adopting of new special methodologies for analyses ofvarious minerals groups,– analysis of bastnesite and REE-carbon<strong>at</strong>e,– analyses of feldspars supplemented on Ba, Sr, P andtrace elements Fe and Mg,– complete programme for ap<strong>at</strong>ite analyses included REE,– programme for corrosive processes analyses and reactionswith various types of environment,– programme for monazite d<strong>at</strong>ing,– programme for analyses of Mn and Fe oxides and carbon<strong>at</strong>es,– programme for Nb-Ta minerals analyses,– one of the most complic<strong>at</strong>ed programmes for analyses ofpyrochlore and similar minerals,– enhancement of the methodology of trace chemical elementsanalyses in minerals,– analyses of HREE in monazites,NV-TU-6p.f.u.1,00,90,80,70,60,5p.f.u.0,030,020,010,00Line profile of clinopyroxene.clinopyroxeneLength is about 440 m.CrMg#Ti– analyses of Fe and P in feldspars,– analyses of Hf in zircon,– enhancement of the methodology ofaccur<strong>at</strong>e measurement of Th, U andPb in monazite, advancement of themethodology of monazite d<strong>at</strong>ing,– definition of influence of C and Auevapor<strong>at</strong>ion pl<strong>at</strong>ing of samples formonazite d<strong>at</strong>ing,– enhancement of the methodologyof recording of c<strong>at</strong>hodoluminiscencyof minerals, etc.BEI image of magnetite inortopyroxene.The labor<strong>at</strong>ory of raster electronmicroscope (SEM) is equipped withthe facility JEOL JSM-840. The appar<strong>at</strong>usenables to take SEI imageswith maximum magnifying of 30 000x.The appar<strong>at</strong>us is utilized for palaeontologicaland environmental purposes;it provides a complex service in samplesprepar<strong>at</strong>ion and processing fromtheir evapor<strong>at</strong>ion pl<strong>at</strong>ing till the photodocument<strong>at</strong>ion.The labor<strong>at</strong>ory equipped with SEI image of nannoplankton.brushing and polishing facilities forsamples prepar<strong>at</strong>ion of the CompanySTRUERS (Denmark) provides m<strong>at</strong>erialscutting and polishing, prepar<strong>at</strong>ionof thin sections and polished thin sections,polished specimens, as well asspecial oriented samples and pl<strong>at</strong>esfor gaseous-fluid inclusions study.The labor<strong>at</strong>ory of fluid inclusionsresearch is equipped with thefacility LINKAM II for analyses of homogenizingtemper<strong>at</strong>ures and temper<strong>at</strong>uresof fluid inclusions fusion. The results of fluid inclusionsCL image of quartz.measurements have been adopted in solutions of petrologicalissues of the geological projects in the scope of the SGIDŠ.The high-quality optic microscopes NIKON and JENAPOLwere used for microphotographs acquisition.The works continued in the scope of the TSÚS Br<strong>at</strong>islava order(Technical and Testing Institute of Constructions) for elabor<strong>at</strong>ionof simplified petrographic descriptions of aggreg<strong>at</strong>e exploitedin selected regions of the Western Carp<strong>at</strong>hians according to STNEN 932-3:1999, which is in accord with valid European StandardEN 932-3:1996/A1. The elabor<strong>at</strong>ed petrographic descriptions ofaggreg<strong>at</strong>e may serve as groundwork for individual exploiting organis<strong>at</strong>ionsin their acceptance <strong>at</strong> EU markets.<strong>St<strong>at</strong>e</strong> <strong>Geological</strong> Institute of Dionýz Štúr Annual Report 2007 19
