An old David Shannon stock specimen with the label stating that it is a very pure Mn end member. That is, in the Triphylite-Lithiophilite series, where Triphylite is the lithium end member, while Lithiophilite is the Mn end member. Usually both minerals are somewhere in between that series. It is all the salmon pink area occuring much like the "salmonsite" which occured at the Stweart mine of the Pala district. It is a primary phosphate found chiefly if not exclusively in pegmatites.
