studtite
Sign in to saveStudtite, chemical formula [(UO2)O2(H2O)2]·2(H2O) or UO4·4(H2O), is a secondary uranium mineral containing peroxide produced by the alpha-radiolysis of water during its formation. It occurs as pale yellow to white needle-like crystals often in acicular, white sprays.

Studtite, chemical formula [(UO2)O2(H2O)2]·2(H2O) or UO4·4(H2O), is a secondary uranium mineral containing peroxide produced by the alpha-radiolysis of water during its formation. It occurs as pale yellow to white needle-like crystals often in acicular, white sprays.
Vaes initially described studtite in 1947 from specimens from Shinkolobwe, Katanga Copper Crescent, Katanga (Shaba), Democratic Republic of Congo, and has since been reported from several other localities. The mineral was named for Franz Edward Studt, an English prospector and geologist who authored the first geological map of Katanga in 1913.
