Fermiite is named after which Italian physicist?
Fermiite Fermiite is a rare uranium mineral with the formula Na(UO)(SO)·3HO. 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).
Greigite Greigite is an iron sulfide mineral with formula FeS (Iron(II,III) sulfide). It is the sulfur equivalent of the iron oxide magnetite (FeO). It was first described in 1964 for an occurrence in San Bernardino County, California, and named after the mineralogist and physical chemist Joseph W. Greig (1895–1977).
