Torbernite

Not to be confused with Tobermorite, a Calcium Silicate Hydrate (CSH), one of the main constituents of cement paste.

Not to be confused with Torbanite, also known as boghead coal, a variety of fine-grained black oil shale.

Torbernite, whose name derives from the Swedish chemist Torbern Bergman (1735-1784), is a radioactive, hydrated green copper uranyl phosphate mineral, found in granites and other uranium-bearing deposits as a secondary mineral. Torbernite is isostructural with the related uranium mineral, autunite.
