McGillite - Sold


McGillite is a rare hydrated manganese silicate related to friedelite. Donnay et al. (1980) named the mineral after McGill University. This is one of a very few minerals (also carletonite) named after a university. Stevenson et al. (1984) provide further details of the mcgillite discovery and occurrence. This is a small fragment of mcgillite, showing basal cleavage with some attached black sphalerite. This specimen was part of the personal collection of Ralph Merrill, proprietor of the prolific mail order business Minerals Unlimited. Ralph Merrill obtained this specimen from Forrest Cureton in 1983. There is a label from the Geological Survey of Canada.
