"The southeastern portion of the Athabasca basin hosts the largest high-grade unconformity-related uranium deposits in the world, including the McArthur River and Key Lake deposits. As a first step of an effort to reconstruct and model the fluid flow related to uranium mineralization, a 3D model of the sub-Athabasca unconformity and basin stratigraphy has been constructed using publicly available geological, geophysical and drill-hole data. Several cross-sections have been built and integrated into the 3D model to constrain the spatial configuration of Athabasca Group units. Faults have been identified using an iterative approach where potential fault lineaments were identified using the basement geophysical signature then confirmed by the presence of spatial relationships to offsets of the unconformity surface. Using this approach, three dominant sets of faults, inferred to be subvertical, have been identified in the study area: northeast trending, north-northwest trending and northwest trending"--Abstract, page [2].
