This page is currently not sponsored. Click here to sponsor this page.
Formula:
Ca3Al8(PO4)2O12 · 2H2O
Name:
Named for the Mt. Uzumine feldspar mining area. (Udumine is a variant orthography no longer current.)
Inadequate data. Grandfathered as a questionable species. Its existence is doubtful.
Occurs as white acicular crystals in cracks in perthite. [Clark, 1993 - "Hey's Mineral Index"]
