Pyrrhotite, Fluorite, Muscovite

Source volume: 54, issue: 3, PDF page: 25. Label: Figure 14. Pyrrhotite crystal coated by a drusy crust of muscovite (?) crystals on the front pinacoid face, along with lustrous cubic galena crystals and purple cubic fluorite crystals, 13.5 cm, from the Bairendaba deposit. This is the finest specimen from the 2019 pocket, and certainly one of the finest known for the species. Rob Lavinsky (The Arkenstone) specimen, now in the Carabas collection; Robert Mosley photo.
