What is metatorbernite?

Metatorbernite is a mineral that belongs to the phosphate family. It is a green to yellow-green colored mineral that is commonly found in oxidized uranium deposits. Its chemical formula is Cu(UO2)2(PO4)2·8-12H2O, which means it contains copper, uranium, phosphorous, and water molecules.

Metatorbernite is a secondary uranium mineral that is formed through the oxidation of primary uranium minerals like uraninite or carnotite. It is commonly found in association with other uranium minerals such as torbernite, autunite, and zeunerite.

Metatorbernite has a high specific gravity and is radioactive due to the presence of uranium. Its radioactivity makes it useful in radiometric dating techniques and the study of uranium deposits. However, it is also considered a health hazard due to its radioactivity.

Metatorbernite was first discovered in 1864 in the Saxon Ore Mountains in Germany. It is named after its association with torbernite, another common uranium mineral, and "meta," which means altered or transformed.
