|Abstract||The Mount Prudence area (NTS 94-N/05) in the western Liard Basin is underlain by Middle Proterozoic to Triassic strata. Poorly exposed Triassic siltstone and shale form the dominant level of exposure.
Folds dominate the structural style. These probably formed in the latest Cretaceous and are well exposed along Liard River and where outlined by more resistant units. Two significant faults (Sulphur Creek and Forcier) carry Middle Devonian and older
strata to the surface. A regionally significant change in the orientation of structures from northwest in the Rocky Mountain Foothills to north or northeast in the Mackenzie Mountains and Liard fold and thrust belt occurs in the northern part of the
area. This map incorporates extensive observations from a major unpublished geological study of the Liard River corridor prepared for B.C. Hydro in 1984 as well as new data collected during fieldwork as part of the Geo-mapping for Energy and Minerals
|Summary||(Plain Language Summary, not published)|
This is the first 1:50 000 scale geological map of the Mount Prudence area, in the Liard Basin of northeast British Columbia. It shows the surface
distribution and structure of the exposed 1 billion to 200 million year old strata. Folds dominate the structure at surface. Only two signigicant faults occur in the area. These expose older (greater than 385 million year old)strata in the west.
The map incorporates new data collected by the GEM project as well as extensive historical observations from a major unpublished geological study. The map and associated studies should be of interest to the petroleum industry when the price of
natural gas rises and exploration moves westward in the Liard Basin area.
