Uranium mica
Uranium mica are minerals of uranium whose common property is the very good and fine (leafy) cleavage ( mica ) and bright color (yellow, green, orange, red). Due to their similar crystal structures, some uranium mica can form mixed crystals or oriented adhesions ( epitaxies ). For example, there are often crystals with a core made of uranocircite and a rim made of torbernite . Many uranium mica also fluoresce under UV light .
Well-known and common uranium mica include autunite , uranocircite , torbernite and zeunerite . These are mostly uranium phosphates , uranium arsenates , uranium silicates , uranium hydroxides or uraniumates . There are also some rare uranium-containing selenites and tellurites that are similar to uranium mica.
