Mineralpedia Details for Mcgillite
Named for McGill University of Montreal in Quebec, Canada where some of the type material for the species is hosted. At the type locality at the Sullivan mine in British Columbia, Canada, Mcgillite forms as fracture fillings in a manganese-rich portion of quartzite and argillite all within a metamorphosed lead-zinc deposit. Mcgillite is rare and occurs on only two other localities in Romania and Japan.
