Adolf Pabst
Adolf Pabst (30 November 1899, Chicago – 3 April 1990, Berkeley, California) was an American mineralogist and geologist. Biography Pabst received in 1925 his bachelor's degree at the University of Illinois and in 1928 his Ph.D. in geology and mineralogy at the University of California, Berkeley under George D. Louderbeck with a thesis on mineral inclusions in the granitic plutons of the Sierra Nevada. For the academic year 1928/29 he won an American-Scandinavian Foundation fellowship for postdoctoral study; on this postdoc under Victor Moritz Goldschmidt in Oslo, Pabst married Gudrun Lisabeth Bert. After returning to Berkeley, he became in 1929 an instructor, in 1931 an assistant professor, in 1936 an associate professor, and in 1944 a full professor. In the academic year 1938/39 he was a Guggenheim Fellow at the Natural History Museum in London and in the academic year 1955/56 a Fulbright Fellow at the University of Vienna.

University Of Illinois Alumni
A university () is an institution of higher (or tertiary) education and research which awards academic degrees in several academic disciplines. Universities typically offer both undergraduate and postgraduate programs. In the United States, the designation is reserved for colleges that have a graduate school. The word ''university'' is derived from the Latin ''universitas magistrorum et scholarium'', which roughly means "community of teachers and scholars". The first universities were created in Europe by Catholic Church monks. The University of Bologna (''Università di Bologna''), founded in 1088, is the first university in the sense of: *Being a high degree-awarding institute. *Having independence from the ecclesiastic schools, although conducted by both clergy and non-clergy. *Using the word ''universitas'' (which was coined at its foundation). *Issuing secular and non-secular degrees: grammar, rhetoric, logic, theology, canon law, notarial law.Hunt Janin: "The university ...

Pabstite
Pabstite is a barium tin titanium silicate mineral that is found in contact metamorphosed limestone. It belongs to the benitoite group of minerals. The chemical formula of pabstite is . It is found in Santa Cruz, California. The crystal system of the mineral is hexagonal. Composition Pabstite is 37.7% SiO2, 3.8% TiO2, 24.4% SnO2 and 33.2% BaO. However, Ti and Sn could vary from point to point by approximately ±0.5% TiO2 and ±1% SnO2. Pabstite is a tin bearing analog of benitoite. Although, (Sn4+ = 0.71 Å) and (Ti4+= 0.68Å) have similar charge and ionic size, it is uncommon to find them substituting each other. Geologic occurrence Pabstite commonly occurs as anhedral crystals and masses that vary in their color from colorless to white.Dunning, G. E & Cooper, J. F. Jr. (1986). "Mineralogy of the Kalkar Quarry, Santa Cruz, California." '' Mineralogical Record, 17'', 315- 326. They produce a pink tinge when they are freshly broken. Large amounts of pabstite were found in ...

International Mineralogical Association
Founded in 1958, the International Mineralogical Association (IMA) is an international group of 40 national societies. The goal is to promote the science of mineralogy and to standardize the nomenclature of the 5000 plus known mineral species. The IMA is affiliated with the International Union of Geological Sciences (IUGS). The Association supports the activities of Commissions and Working Groups involved on certain aspects of mineralogical practice and facilitates interactions among mineralogists by sponsoring and organising meetings. In particular, the IMA holds its general meeting every four years. The next meeting is scheduled in 2022 in Lyon, France. Presidents The presidents of the IMA have been: * since 2021: Anhuai Lu ** Peking University *2018–2020: Patrick Cordier (born 1961) ** Université de Lille *2016–2018: Peter C.

Macdonaldite
Macdonaldite is a rare barium silicate mineral with a chemical formula of BaCa4Si16O36(OH)2·10H2O.Alfors, J.T., Stinson, M.C., Matthews, R.A., and Pabst, A. (1965) Seven new barium minerals from eastern Fresno County, California. American Mineralogist, 50, 314-340. Macdonaldite was first described in 1965 and named for Gordon A. Macdonald (1911–1978) an American volcanologist at the University of Hawaii. Macdonaldite crystallises in the orthorhombic system. Macdonaldite is anisotropic with low relief.Bloss, F.D. (1999) Optical Crystallography. Mineralogical Society of America, 5, 161-163. Macdonaldite appears as veins and fracture coatings in a sanbornite and quartz bearing metamorphic rock. Macdonaldite was first described in 1965 for an occurrence near the Big Creek-Rush Creek area in Fresno County, California. It has also been reported from Mariposa and Tulare counties in California. It has also been reported from a quarry in San Venanzo, Umbria it, Umbro (man) i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Huttonite
Huttonite is a thorium nesosilicate mineral with the chemical formula and which crystallizes in the monoclinic system. It is dimorphous with tetragonal thorite, and isostructual with monazite. An uncommon mineral, huttonite forms transparent or translucent cream–colored crystals. It was first identified in samples of beach sands from the West Coast region of New Zealand by the mineralogist Colin Osborne Hutton (1910–1971). Owing to its rarity, huttonite is not an industrially useful mineral. Occurrence Huttonite was first described in 1950 from beach sand and fluvio-glacial deposits in South Westland, New Zealand, where it was found as anhedral grains of no more than 0.2 mm maximum dimension. It is most prevalent in the sand at Gillespie's Beach, near Fox Glacier, which is the type location, where it is accompanied by scheelite, cassiterite, zircon, uranothorite, ilmenite and gold. It was found at a further six nearby locations in less plentiful amounts. Hutt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
