Biogenic non-crystalline U(IV) revealed as major component in uranium ore deposits
Abstract
Crystalline uraninite is believed to be the dominant form in uranium deposits. Here, the authors find that non-crystalline U(IV) generated through biologically mediated U(VI) reduction is the predominant U(IV)species in ore deposits, implying that biogenic processes are more important than previously thought.
