...T. W. Stern; L. R. Stieff; M. N. Girhard; Robert Meyro-witz Abstract Metatyuyamunite [Ca(UO 2 ) 2 (VO 4 ) 2 · 3-5 H 2 O], a new mineral, is a dehydration product of tyuyamunite [Ca(UO 2 )2(VO 4 ) 2 · 5-8.5 H 2 O]. This lower hydrate of tyuyamunite has been collected from more than 35 localities...

... in the deposition history of cave minerals. Groundwater percolating through the breccia-pipe bodies mobilized and transported ore-related ions into the cave, where they formed a unique assemblage of minerals ( i.e., hörnesite, talmessite, carnotite, tyuyamunite, claudetite, and powellite) that mirror breccia-pipe...

...Yehuda Eyal; Aaron Kaufman; Miryam Bar-Matthews Abstract Crusts of uranium minerals, carnotite and tyuyamunite, were found along some fault planes in the northern Negev, Israel. Field, microscope, and scanning electron microscope (SEM) examinations of the carnotite showed that they crystallized...

..., the “Kupferschiefer-type” copper deposits in southwestern Oklahoma (Creta and Mangum) contain only up to 12 ppm U. In southwestern Oklahoma (Clinton 2 × 1° Quadrangle) carnotite and tyuyamunite occur in siltstones of the basal part of the Doxey formation. Although the origin of the mineralization is not entirely...

..., spectrographic study, crystallographic measurement, and optical study combine to suggest that the material described is related to carnotite and tyuyamunite, but differs chemically in that it is a definite copper-bearing species. In crystallization it may be quite similar to the other two minerals. Copyright ©...
