Formula:
Fe2+Al2(PO4)2(OH)2
Colour:
Dark azure blue, green-blue, blue-green
Lustre:
Sub-Vitreous, Resinous, Greasy
Crystal System:
Monoclinic
Name:
Named in 1949 by William Thomas Pecora and Joseph John Fahey in honor of Brazilian mineralogist, Evaristo Penna Scorza [August 20, 1899 Lavras, Minas Gerais, Brazil - March 29, 1969 Brazil]. Scorza was a field geologist, as well as an administrator later in his career. He published on a wide range of geological topics although many of his research papers were mineralogical. Pronounced scor'-za-lite.
