Belakovskiite

A variety of Minerals

What is Belakovskiite?

Belakovskiite is a very rare uranium mineral with the formula Na7(UO2)(SO4)4(SO3OH)(H2O)3. It is interesting in being a natural uranyl salt with hydrosulfate anion, a feature shared with meisserite. Other chemically related minerals include fermiite, oppenheimerite, natrozippeite and plášilite. Most of these uranyl sulfate minerals was originally found in the Blue Lizard mine, San Juan County, Utah, US. The mineral is named after Russian mineralogist Dmitry Ilych Belakovskiy.
