ProgramGEM2: Geo-mapping for Energy and Minerals Mackenzie Corridor, Shield to Selwyn
Released2017 11 16
Northern Mackenzie Mountains bedrock mapping and stratigraphic studies are a component of the Mackenzie-Selwyn geo-transect: studying the evolution of sedimentary rocks of the northern mainland NWT to improve exploration success for petroleum resources and base metal deposits (Figure 1). This activity will initiate the first regional integrated effort to place Proterozoic to Cenozoic strata of the Mackenzie Platform, Selwyn Basin, and adjacent regions into a modern tectono-stratigraphic and metallogenic framework, and will better enable industry and Northerners to responsibly find and develop energy and mineral natural resources, maximizing their economic and societal impact.
This report provides a short account of the field activities in the Bonnet Plume map area (NTS 106B) of the Mackenzie Mountains (NWT). Fieldwork was conducted by the Devonian paleontology team, as part of the Arctic Red field party (MacNaughton et al., 2017), between July 4 and July 20, 2017. Information presented in this report concerns the biostratigraphic and lithostratigraphic characterization of Devonian units related to the geological mapping of the area.
Summary(Plain Language Summary, not published)
This Open File reports on the 2017 fieldwork of the Devonian paleontology team (GEM2 Mackenzie Project) in the Northern Mackenzie Mountains, NWT. The crew described and sampled three sections in the Middle-Upper Devonian Horn River Group for conodont biostratigraphy and palynology. Focus is on the contact between the Hume and Canol formations to locate the base of the Givetian stage (Middle Devonian) and obtain detailed age constraint data on the Canol Formation in the Bonnet Plume map area (NTS106B) in support of bedrock mapping. Conodonts are an extinct marine protochordate group and the fast morphological evolution of their hard tissue teeth-like remains is used to constrain the age of calcareous Paleozoic rocks. Palynology is the study of palynomorphs (pollen and spores) and provides information on the paleoenvironment and age constraint of organic rich shales. Their combination will provide us with a strong age control on the upper Hume Formation and the Canol Formation for correlation of the new sections with the regional and global stratigraphy.
