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