AbstractRegional examination and integration of geochemical data with other components of the uranium exploration model can influence
mineral exploration. This approach was applied to regional geochemical data for the Athabasca Basin, northern Saskatchewan, Canada,
which is host to some of the world's most significant high grade unconformity-associated uranium deposits. Four distinct geochemical
signatures are described, each reflecting portions of processes responsible for uranium mineralization, associated alteration, and
background geology. These signatures are significant in that they 1) are present in the exposed and near-surface rocks of the Athabasca
Basin; 2) correspond with lineament traces, and highlight lineament intersections that are loci for uranium mineralization, and 3)
partially define a distinct but locally stratabound hydrothermal signature that is possibly temporally and genetically related to focused
uranium deposition elsewhere in the Athabasca Basin, but is also expressed in the Wolverine Point Formation.
Summary(Plain Language Summary, not published)
The Targeted Geoscience Initiative (TGI-4) is a collaborative federal geoscience program that provides industry with the next generation of geoscience knowledge and innovative techniques to better detect buried mineral deposits, thereby reducing some of the risks of exploration. This scientific presentation open file highlights geochemical exploration applications of the recently released Athabasca uranium geochemistry database (Wright et al., 2014, GSC OF7495). Through examination of the geochemical database, examples are shown of geochemical signatures related to deeply-buried uranium mineralization that are visible on a regional scale and which may represent new exploration targets. Furthermore, spatial associations between these signatures, lithology and structural elements provide further insights on possible metal/fluid sources and conduits related to formation of the uranium deposits.
