Structural controls on roll-front mineralization at the Buss Pit deposit, Gas Hills district, Wyoming
A significant portion of the world's uranium resources are hosted by sandstone-hosted roll-front deposits. This type of deposit is an attractive exploration target as it is amenable to in situ mining methods. Roll-front deposits form when oxidized, uranium-bearing groundwater encounters a redox boundary creating a crescent-shaped ore body. Reducing conditions downstream of the ore body are thought to be maintained by the presence of diagenetic pyrite or organic material within the host aquifer. However, some roll-front deposits occur within aquifers that contain only low amounts of in situ ...
