| Abstract | The Aubry Lake map area (NTS 96-M) lies within the Colville Hills region of the Northwest Territories. Sparse bedrock exposures in the area include carbonate and siliciclastic strata ranging from
Cambrian to Cretaceous. These strata were deformed in the Cretaceous to Eocene by folding and contractional faulting associated with Cordilleran deformation. Divergent structural trends are interpreted to be inherited from Proterozoic structures in
the subsurface. A major unconformity between Devonian and Cretaceous strata is marked by tilted Paleozoic strata beneath the Cretaceous. Natural gas has been reported from petroleum exploration wells drilled into Mount Clark Formation (Cambrian)
sandstone. |
| Summary | (Plain Language Summary, not published)
This publication is a new bedrock interpretation at 1:250,000 scale for the Aubry Lake map area (NTS 96M). Stratigraphic and structural features have
been reinterpreted based on field observations, petroleum exploration well data, and reflection-seismic data. |
