Autunit – Wikipedia

Autunit (auch Kalkuranglimmer) ist ein häufig vorkommendes Mineral aus der Mineralklasse der „Phosphate, Arsenate und Vanadate", das zur Gruppe der Uranglimmer gehört. Es kristallisiert im orthorhombischen Kristallsystem mit der chemischen Zusammensetzung Ca[(UO 2)(PO 4)] 2 ·11 H 2 O und ist daher chemisch betrachtet ein Calcium-Uranyl-Phosphat.
