Geology, Mahony Lake (southeast), Northwest Territories / [by] K.M. Fallas.: M183-1/90-2012E-PDF
"The southeast quadrant of the Mahony Lake map area (NTS 96-F) straddles the boundary between the Great Bear Plain and the Franklin Mountains, Northwest Territories. The mountain range extending north-northwest from Mount St. Charles (informally known as the St. Charles range), overlooks an area dominated by a low, undulating, forested plain with very sparse bedrock exposure. The west-flowing Great Bear River dissects both the Great Bear Plain and the St. Charles range. The plain is underlain by flat-lying to gently folded Cretaceous sedimentary strata. Folded and faulted Paleozoic carbonate strata are exposed at surface along the St. Charles range. The steep reverse faults truncating anticlinal folds are associated with Cordilleran deformation at the eastern edge of the Franklin Mountains. Cretaceous strata are preserved unconformably above Devonian strata on either side of the St. Charles range. Historical exploration by petroleum companies in the area targeted potential reservoirs in buried Cambrian strata. Public-domain seismic-reflection profiles archived with the National Energy Board were used to help constrain the distribution of map units and structures"--Abstract.
