Fluorite - Wikipedia

He noted an occurrence of "galena" or lead ore and fluorite of lime on the west side of St. Lawrence harbour. It is recorded that interest in the commercial mining of fluorspar began in 1928 with the first ore being extracted in 1933. Eventually at Iron Springs Mine, the shafts reached depths...

Mineral Preservation - Mineralogical Society of America

Brilliant marcasite crystals have frequently been found by the writer on old mine dumps in association with calcite, barite and fluorite while specimens from certain lead and zinc mines gradually disintegrate in the mineral cases. The extremely rapid oxidation of marcasite in coal is difficult to explain but is a well known fact.
