Sedimentary environments

Rauvite is a rare mineral occurring in the oxidised zones of uranium-vanadium ores in Colorado Plateau-type deposits associated with carnotite, corvusite, uvanite, hewettite, metatorbernite, tyuyamunite and gypsum (HOM).

Localities

There are two co-type localities, Flat Top Mesa and Temple Mountain, both at the San Rafael Mining District, Emery county, Utah, USA. Here rauvite occurs as fissure fillings or impregnations in sandstone. Associated Minerals include uvanite, tyuyamunite, metatorbernite, hewettite, gypsum, corvusite and carnotite (Mindat)
