ProgramGEM2: Geo-mapping for Energy and Minerals Mackenzie Corridor, Shield-to-Selwyn geo-transect, Mackenzie-Selwyn sub-activity
Released2018 10 31
The fieldwork documented in this report is part of the "Shield-to-Selwyn geo-transect: studying the evolution of sedimentary rocks of the northern mainland NWT". This activity is a regional, integrated effort to place the bedrock of Mackenzie Mountains, Franklin Mountains, and the adjacent interior plains into a modern stratigraphic framework, while updating bedrock maps for the Colville Hills and northern Mackenzie Mountains. This will better enable industry and Northerners to responsibly find and develop energy and mineral natural resources, while making informed land-use decisions, thereby helping to optimize economic and societal impact.
This report summarizes fieldwork in the Mackenzie Mountains, NWT, during July and early August, 2018 (Figure 1). Most of the work was in Bonnet Plume Lake (NTS 106-B) map area (Figure 2). At the end of the field season, we carried out several days of reconnaissance work in Wrigley Lake (NTS 95-M) map area (Figure 2), including several site visits in adjacent map areas: Glacier Lake (NTS 95-L) and Sekwi Mountain (NTS 105-P). The preliminary results presented here focus on bedrock geological mapping, stratigraphy, and structural geology.
Summary(Plain Language Summary, not published)
The report is an account of geological field work carried out by the GSC field party in the Mackenzie Mountains, summer, 2018. The report covers work done in the fields of bedrock mapping, stratigraphy, and structural geology. It includes a brief summary of new geological observations.
