"The northwest quadrant of the Mahony Lake map area (NTS 96-F) encompasses a low, vegetated plateau at the western edge of the Great Bear Plain, Northwest Territories. The somewhat higher ground between Mahony Lake and the Hare Indian River to the north is informally referred to as the Mahony dome. Most of the area is underlain by broadly folded Paleozoic carbonate strata, disrupted locally by steep reverse faults. The structural features suggest a geological kinship with the Franklin Mountains to the west. Due to a veneer of unconsolidated Quaternary deposits, bedrock exposures are not abundant; however, the presence of carbonate very close to surface has allowed for the development of numerous karst features, such as sinkholes, disappearing streams, and turloughs, where bedrock may be exposed. Cretaceous siliciclastic strata are preserved in a synclinal structure west of Mahony Lake. Truncations of Ordovician to Devonian strata beneath the sub-Cretaceous unconformity delineate part of the Keele Arch, a feature that stood topographically higher than the surrounding area before deposition of the Devonian strata, and again before deposition of the Cretaceous strata"--Abstract.
