ABSTRACT Mason, Brian, editor. Mineral Sciences Investigations 1974-1975. Smithsonian Contributions to the Earth Sciences, number 19, 125 pages, 48 figures, 37 tables, 1977.—Nine short contributions from the Smithsonian's Department of Mineral Sciences for 1974 and 1975 are gathered together in this volume. These contributions comprise an account of the composition of garnet xenocrysts from three kimberlite pipes in Arizona and New Mexico; a catalog of major element chemistry of abyssal volcanic glasses, and the application of these data to determine magma compositions; descriptions of the Harleton (Texas), St. Mary's County (Maryland), and Ras Tanura (Saudi Arabia) chondritic meteorites; a comparative study of eight chondrite meteorites from India and Pakistan; geochemical data on separated components of the Allende carbonaceous chondrite; and a mineralogical and chemical study of silicate inclusions in the El Taco mass of the Campo del Cielo iron meteorite. OFFICIAL PUBLICATION DATE is handstamped in a limited number of initial copies and is recorded in the Institution's annual report, Smithsonian Year.
