    U.S. DEPARTMENT OF THE INTERIOR GEOLOGICAL SURVEY THE FORD-FLEISCHER FILE OF MINERALOGICAL REFERENCES, 1978-1980 INCLUSIVE by Michael Fleischer and Constance M. Schafer Open-File Report 81-1174 This report is preliminary and has not been reviewed for conformity with U.S. Geological Survey editorial standards 1981 The Ford-Fleischer File of Mineralogical References 1978-1980 Inclusive by Michael Fleischer and Constance M. Schafer In 1916, Prof. W.E. Ford of Yale University, having just published the third Appendix to Dana's System of Mineralogy, 6th Edition, began to plan for the 7th Edition. He decided to create a file, with a separate folder for each mineral (or for each mineral group) into which he would place a citation to any paper that seemed to contain data that should be considered in the revision of the 6th Edition. He maintained the file in duplicate, with one copy going to Harvard University, when it was agreed in the early 1930's that Palache, Berman, and Fronde! there would have the main burden of the revision. A number of assistants were hired for the project, including C.W. Wolfe and M.A. Peacock to gather crystallographic data at Harvard, and Michael Fleischer to collect and evaluate chemical data at Yale. After Prof. Ford's death in March 1939, the second set of his files came to the U.S. Geological Survey and the literature has been covered since then by Michael Fleischer. Copies are now at the U.S. Geological Survey at Reston, Va., Denver, Colo., and Menlo Park, Cal., and at the U.S.

Santaclaraiteis a five-tetrahedral-repeatsingle-chain silicate and has structural affinities with rhodonite, nambulite, marsturite, babingtonite, and inesite. Introduction about fifty abandonedmanganese mines located in Santa The new mineral santaclaraitewas discovered in 1975 Clara, Alameda, San Joaquin, and Stanislaus Counties in an abandonedmanganese mine in the Diablo Range in near their common junction.

Articles of the volume are devoted to mineralogy, including descriptions of new mineral species (telyushenkoite – a new caesium mineral of the leifite group, neskevaaraite-Fe – a new mineral of the labuntsovite group) and new finds of min- erals (pabstite from the moraine of the Dara-i-Pioz glacier, Tadjikistan, germanocolusite from Kipushi, Katanga, min- erals of the hilairite group from Khibiny and Lovozero massifs). Results of study of mineral associations in gold-sulfide- tellyride ore of the Kairagach deposit, Uzbekistan are presented. Features of rare germanite structure are revealed. The cavitation model is proposed for the formation of mineral microspherulas. Problems of isomorphism in the stannite family minerals and additivity of optical properties in minerals of the humite series are considered. The section Mineralogical Museums and Collections includes articles devoted to the description and history of Museum collections (article of the Kolyvan grinding factory, P.A.Kochubey's collection, new acquisitions) and the geographical location of mineral type localities is discussed in this section. The section Mineralogical Notes includes the article about photo- graphing minerals and Reminiscences of the veteran research worker of the Fersman Mineralogical Museum, Doctor in Science M.D. Dorfman about meetings with known mineralogists and geochemists – N.A. Smoltaninov, P.P. Pilipenko, Yu.A. Bilibin. The volume is of interest for mineralogists, geochemists, geologists, and to museum curators, collectors and amateurs of minerals.
