Belakovskiite is a very rare uranium mineral with the formula Na7(UO2)(SO4)4(SO3OH)(H2O)3.[2][3] It is interesting in being a natural uranyl salt with hydrosulfate anion, a feature shared with meisserite.[5] Other chemically related minerals include fermiite, oppenheimerite, natrozippeite and plášilite.[6][7][8][9] Most of these uranyl sulfate minerals was originally found in the Blue Lizard mine, San Juan County, Utah, US.[10] The mineral is named after Russian mineralogist Dmitry Ilych Belakovskiy.[2]

Association

Belakovskiite is associated with other sulfate minerals: meisserite, blödite, ferrinatrite, kröhnkite, and metavoltine.[2] This association is found as efflorescences on a sandstone associated with uranium mineralization.[4]

Crystal structure

The framework of belakovskiite crystal structure is a hexavalent cluster with composition (UO2)(SO4)4(H2O). Such clusters are connected via Na-O and hydrogen bonds.[2]
