Shumwayite is a rare[2] but relatively simple uranyl sulfate mineral with the formula (UO2)2(SO4)2•5H2O. It was discovered in the Green Lizard and Giveaway-Simplot mines of the White Canyon mining district, San Juan County, Utah, US.[1]
Relation to other minerals
The structure of shumwayite is unique.[1] Somewhat chemically similar natural uranyl sulfates include jáchymovite, metauranopilite and uranopilite.[3][4][5]
