Kingsmountite, Birnessite & Mitridatite ex Henderson Coll.

Item Description

The well-known Foote Mine is a lithia-bearing pegmatite and is famous for a variety of rare phosphates and silicates. Kingsmountite is a very rare phosphate and this mine is the Type Locality. Birnessite is an uncommon manganese hydroxide and mitridatite is another rare phosphate. All three plates host micro sprays of white kingsmountite crystals, lustrous black birnessite and much olive-green mitridatite. Birnessite is very uncommon from the Foote Mine and these are excellent and rich combination thumbnails from the Will Henderson Collection, obtained through Jim Fowler.
