CaUO22VO425H2O
CaUO22VO425H2O is a hydrated calcium uranyl vanadate mineral. Its chemical formula indicates it is composed of calcium (Ca), uranium (U), oxygen (O), and vanadium (V), with a significant water content (25 molecules). This compound is known to form as a secondary mineral, meaning it is found in association with the weathering and alteration of primary uranium and vanadium-bearing minerals. Specifically, it is often found in oxidized ore bodies. The presence of uranium and vanadium suggests potential for radioactivity. Crystals of CaUO22VO425H2O are typically small and prismatic, and the mineral can exhibit a range of colors, often yellow to orange or brown, depending on the specific oxidation states and impurities present. It is a relatively rare mineral, primarily of interest to mineral collectors and researchers studying secondary uranium mineralization processes. Its geological occurrence is typically in arid or semi-arid environments where weathering of uranium-rich rocks is prevalent. The specific arrangement of atoms and the hydration contribute to its unique physical and chemical properties.
