WebTorbernite, whose name derives from the Swedish chemist Torbern Bergman (1735-1784), is a radioactive, green phosphate mineral, found in granites and other uranium-bearing deposits as a secondary mineral. Torbernite is isostructural with a related uranium mineral, autunite, with torbernite's lack of fluorescence a notable difference.
