Brushite

Brushite

Brushite is a mineral, formula CaHPO4·2H2O. It is believed to be precursor of apatite and is found in guano-rich caves; formed by the interaction of guano with calcite and clay at a low pH. It forms prismatic monoclinic crystals.http://webmineral.com/data/Brushite.shtml Webmineral data]

The other source of brushite is from calcium phosphate kidney stones, the original precipitating material is usually brushite.

Brushite was first described in 1865 and named for George Jarvis Brush (1831-1912), American mineralogist.
