Report of 2015 activities for the geologic and metallogenic framework of the South Rae Craton, southeast Northwest Territories: GEM 2 South Rae quaternary and bedrock project

Abstract

Foreword The Geo-mapping for Energy and Minerals (GEM) program is laying the foundation for sustainable economic development in the North. The Program provides modern public geoscience that will set the stage for long-term decision making related to investment in responsible resource development. Geoscience knowledge produced by GEM supports evidence-based exploration for new energy and mineral resources and enables northern communities to make informed decisions about their land, economy and society. Building upon the success of its first five-years, GEM has been renewed until 2020 to continue producing new, publically available, regional-scale geoscience knowledge in Canada's North. During the summer 2015, GEM program has successfully carried out 17 research activities that include geological, geochemical and geophysical surveying. These activities have been undertaken in collaboration with provincial and territorial governments, northerners and their institutions, academia and the private sector. GEM will continue to work with these key collaborators as the program advances.

Deformation and extensional exhumation of 1.9 Ga high-pressure granulites along the Wholdaia Lake shear zone, south Rae craton, Northwest Territories, Canada

“…A recent geochronological reconnaissance transect, which was aided by a high-resolution aeromagnetic survey (Kiss and Coyle, 2012), was undertaken across the largely unmapped south Rae craton in NWT. The transect resulted in the delineation of northeast-trending lithotectonic domains (Davis et al, 2015;Pehrsson et al, 2015;Percival et al, 2016;Regis et al, 2017b) that correlate well with similar domains recognized in Saskatchewan (e.g., Ashton et al, 2007).…”

Assessment of Convolution Neural Networks for Surficial Geology Mapping in the South Rae Geological Region, Northwest Territories, Canada

“…Permafrost is extensive and discontinuous with low to medium ice content throughout the ecoregion. More detailed descriptions of the region's geology and landscape can be found in [23] Campbell and Eagles [24], Pehrsson et al [25], and Campbell et al In this study, five subareas, within National Topographic System Abitau Lake map sheet 75B ( Figure 1) were used. …”
