He was an author of some 41 articles in international journals and professional volumes as well as 12 field guides and four geologic maps. James Thompson's career was almost entirely at Harvard University. His most widely applauded work was in \"phase space\" studies: \"Then in 1957 with “The Graphical Analysis of Mineral Assemblages in Pelitic Schists,” he introduced graphical projections for the analysis of mineral assemblages in multicomponent systems that led to thermodynamic and conceptual tools for the analysis of chemically open systems and other tools. This work is indelibly woven into the fabric of much of the research on metamorphic rocks being published today.\"  His memberships and awards include: member of the National Academy of Sciences, and American Academy of Arts and Sciences. He received the Arthur L. Day Medal from the Geological Society of America (1964), the Roebling Medal from the Mineralogical Society of America (1979), and the Victor M. Goldschmidt Medal from the Geo-chemical Society (1985). He received a Ford Faculty Fellowship (1952-1953), a Guggenheim Fellowship (1963), and he was an Ernst Cloos Memorial Scholar at Johns Hopkins University (1983) and a Fairchild Distinguished Scholar at California Institute of Technology (1976), among numerous distinguished lectureships. Thompson also received an honorary doctorate from Dartmouth College in Hanover, New Hampshire. He was president of the Mineralogical Society of America in 1967-1968, as well as of the Geochemical Society in 1968 and 1969. He served in the US Armed Services during WWII.","2025-08-11 12:14:19",[],[],[],[],[89],{"id":90,"txt":91,"latitude":92,"longitude":93,"country":94},4195,"Carlton Quarry, Chester, Windsor County, Vermont, USA",43.272196,-72.63321,"USA",3,[97,100,103,108,113],{"id":98,"year":27,"html":99,"doi":11},527128,"Veblen, David R., Burnham, Charles W.
