Time, crustal evolution and generation of uranium deposits,led their distribution in space and through time. Especially emphasized are the evolutionary changes in source of uranium, uranium transport mechanisms and depositional processes that have shaped the different major types of uranium deposits throughout the geological record.

Uranium in mantle processes,eing stable under highly oxidizing conditions.. It does not enter the lattices of most rock-forming minerals, but may be strongly concentrated in accessory minerals.. A large fraction of U in volcanic rocks is concentrated along inter-crystal boundaries, where it is loosely bound, and from where it

Numerous geological descriptions of these major types of uranium deposits have been provided, as well as many discussions and interpretations of the processes that are involved in their genesis. It is not so well recognized, however, that these deposits and genetic
