Uranium in a Nutshell ThoughtCo

The great uranium deposits of northern Saskatchewan, in Canada, are also of sedimentary origin but with a different scenario of much greater age. There an ancient continent was deeply eroded during the Early Proterozoic Era some 2 billion years ago, then was covered by deep layers of sedimentary rock.

Uranium Deposits | Shale | Sedimentary Rock

Uranium deposits are divided into four classes: 1) magmatic deposits; 2) sedimentary syngenetle deposits; 3) sedimentarymetamorphic deposits; 4) weathering deposits. Deposits of the first class include pegmatites, pegmatoid veins, hydrothermal veins, which are formed by the filling of open cavities, and bedding planes of hydrothermal ...
