TORBERNITE (CHALCOLITE), ZAIRE (large cabinet) NOT FOR SALE OUTSIDE AUSTRALIA

Torbernite, often referred to as chalcolite, is a fairly prevalent mineral characterized by the chemical formula Cu[(UO2)(PO4)]2(H2O)12. This hydrated green copper ura phosphate is typically located in granites and other ura deposits as a secondary mineral. Its chemical structure closely resembles that of autunite, with a Cu2+ cation substituting for a Ca2+ cation. Under certain conditions, torbernite can lose water and transform into metatorbernite, which has the formula Cu[(UO2)(PO4)]2(H2O)8.
