Fermiite is a rare uranium mineral with the formula Na4(UO2)(SO4)3·3H2O.[4] Chemically related minerals include oppenheimerite, meisserite (which is also structurally-related to fermiite),[3] belakovskiite, natrozippeite and plášilite.[5][6][7][8][9] Fermiite comes from the Blue Lizard mine, San Juan County, Utah, USA, which is known for many rare uranium minerals.[2][3][10] The name honors Enrico Fermi (1901–1954).[3]

Association

Fermiite is closely associated with numerous other sulfate minerals: oppenheimerite, bluelizardite, wetherillite, blödite, manganoblödite, chalcanthite, epsomite, gypsum, hexahydrite, kröhnkite, sideronatrite and tamarugite.[4]

Crystal structure

The main building block of the crystal structure of fermiite is a chain of the composition (UO2)(SO4)3. Chains are connected with five types of Na-O polyhedra.[4]
