Mineralpedia Details for Phosphophyllite
Phosphophyllite
Named for the phosphate in its chemical composition and for the Greek word fyllo, or phyllo, meaning “leaf,” in reference to Phosphophyllite’s perfect, leaf-like cleavage. Phosphophyllite is an uncommon mineral found as a secondary mineral in granite pegmatites, as an alteration mineral after sphalerite and iron-manganese phosphates, and in hydrothermal vein deposits. Localities for Phosphophyllite include Germany, Sweden, Bolivia, the United States, Australia, and Zambia.
