| Abstract | The stratigraphic succession of the area extends from Proterozoic to Upper Cretaceous, and is interrupted by four or more unconformities. The sub-Cambrian and sub-Cretaceous unconformities are the most
pronounced whereas the sub-Upper Ordovician and sub-Devonian unconformites are less obvious. A fifth unconformity may be present between Lower and Upper Cretaceous shale. The Colville Hills and northern part of the Franklin Mountains reflect
compressional structures, anticlines and thrust blocks, which apparently developed above a decollement in the shale and evaporites of the Cambrian Saline River Formation. The greatest economic potential of the area is for oil and gas. Base metal
possibilities exist in the Proterozoic rocks, which include basalt flows of the Coppermine River Series, and basid dykes and sills . |
