TRIPHYLITE LiFePO4 Orthorhombic
Description: Triphylite forms bluish-green massive material in complex granitic pegmatites. It is often found with many other rare phosphates. Triphylite readily alters to ocherous iron oxides and other iron phosphates.
FLORENCE COUNTY: Occurs as nodules up to 2 cm. in diameter in the complex pegmatite dikes in sec. 22 and sec. 29 T.39N. R.17E. near Fern. The triphylite occurs with heterosite-purpurite, columbite-tantalite, beryl, elbaite, albite, muscovite, microcline, quartz and rarer phosphate minerals. (Steve Koehler, 1989)
