Unconformity-related Uranium potential
The Cariewerloo Basin is seen as having many similarities with the Athabasca Basin, host to several unconformity-related Uranium deposits. Both are intracratonic basins containing Palaeo-Mesoproterozoic, unmetamorphosed and largely undeformed, quartz dominated, fluvial sedimentary rocks.
In addition, both basins unconformably overlie deformed and metamorphosed Palaeoproterozoic and Archaean basement including metasedimentary rocks, such as graphitic schists, and granitoid rocks. Reactivated basement structures that propagate into the basin sediments are also common. Moreover, basement rocks under both basins contain elevated uranium concentrations.
The Cariewerloo Basin 3D Geological Model was developed to assist 3D visualisation and exploration potential of the region for unconformity-related uranium mineralisation. Important aspects of this exploration model are the depth and geometry of the basin-basement surface.
Note: these models are presented as a 'proof of concept' only and their accuracy (spatial or otherwise) should not be relied upon for exploration or other decision making processes.
