Schröckingerite is a radioactive yellow uranium-containing carbonate mineral, hydrated sodium calcium uranyl sulfate carbonate fluoride. 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 Schrockinger von Neudenberg (1814–1882).
