Tyuyamunite is a rare mineral found in uranium deposits. It is a bright, green-yellowish mineral that is often used to indicate the presence of uranium ore. A few synonyms for tyuyamunite include uranocircite, uranothorite, and cuprosklodowskite. These minerals often occur with others such as uraninite, autunite, and carnotite. Tyuyamunite was first discovered in the USA and named after the local Indian tribe of Tyuyamunite. It is known for its high radioactivity levels and can be hazardous if not handled appropriately. Despite its risks, tyuyamunite remains essential for geological studies and for the development of nuclear technology.
