Radioactive yellow uranium-containing carbonate mineral
Schröckingerite is a radioactive yellow uranium-containing carbonatemineral, hydrated sodium calcium uranyl sulfate carbonate fluoride.[3][4][5] Schröckingerite crystallizes in the orthorhombic system, occurring as globular clusters, and fluoresces yellow-green under ultraviolet light.
Schröckingerite was first described in 1783 from an occurrence in Jáchymov, Bohemia, Czech Republic, and named for its discoverer, Julius Freiherr Schröckinger von Neudenberg (1814–1882).[3][5]
