Locality: Anderson pegmatites, Homestead claim, White Picacho Mining dist., Yavapai Co., Arizona, United States
Formula: LiMn²⁺PO₄
Availability: Sold
Size: 16 x 10 x 10 cm - Cabinet
Tagged: beryllium , pegmatite mineral , lithium

Large specimen of salmon colored Lithiophilite partially replaced by yellow Fillowite and green Dickinsonite. These two species would require EDS to distingish the two. The specimen is sawed and polished on one side and shows the Lithiophilite with rounded edges from being eaten away from late solutions or hydrothermal alterations. Columbite is also scattered in the specimen and can be in the fifth photo.

The pegmatites in the White Picacho district of Arizona are Precambrian in age. These pegmatites occur in a belt that trends from the northwest corner of Arizona southeasterly for about 250 milesto the Phoenix area (Mineralogy of Arizona, Anthon, JW et al)

Beautiful salmon colored Lithiophilite altered to Robertsite with minor Eucryptite. Fantastic pegmatite specimen. The sixth photo shaws a fluorescent yellow mineral, which is probably apatite. There may also be a little alteration to Hureaulite and Triploidite.
