Abstract

Tinsleyite, a K-Al phosphate hydroxide dihydrate, is reported in bat guano deposits in the Cioclovina Cave, Sureanu Mts, S Carpathians. EPMA results indicate the presence of variable amounts of leucophosphite (< or = 31.68 mol.%). An iron-poor sample has a 9.638, b 9.522, c 9.540 Aa, beta 103.10 degrees , alpha 1.592, gamma 1.603. Thermal analyses show that water is lost in three steps and that the loss of molecular water is complete before 250 degrees C. The IR spectrum is presented.
