Tyuyamunite
Tyuyamunite (pronounced tuh-YOO-ya-moon-ite) is a very rare uranium mineral with formula Ca(UO2)2V2O8·5-8(H2O). It is a member of the carnotite group. It is a bright, canary-yellow color because of its high uranium content. Also, because of tyuyamunite's high uranium content, it is radioactive.[1] It was named by Konstantin Avtonomovich Nenadkevich, in 1912, after its discovery locality, Tyuya-Muyun, Fergana Valley, Kyrgyzstan.[2]
Formation and transformation
Tyuyamunite is formed by the weathering of uraninite, a uranium-bearing mineral. Tyuyamunite, being a hydrous mineral, contains water. Yet when it is exposed to the atmosphere it loses it water. This process changes tyuyamunite into a different mineral known as metatyuyamunite.[1]
