| Abstract | (unpublished)
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 2014, GEM's new research program has been launched with 14 field 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. |
| Summary | (Plain Language Summary, not published)
The Thelon tectonic zone project addresses scientific questions relevant to the mineral exploration industry in NTS map sheets 76H and 76I. Bedrock
mapping mostly along two transects in 76H resulted in recognition of (1) nine crustal domains with distinct aeromagnetic and lithological characteristics, (2) a number of kinematically diverse high-strain zones, (3) 7 new gossans. Samples were
collected for geochemical and geochronological analysis. Magnetotelluric data obtained from 2 transects correlate with crustal domains. Reconnaissance surficial geology maps were tested by ground-truthing and aerial observations. Cross-cutting striae
and glacially-molded bedrock surfaces indicate northward regional ice flow shifted northwestward. Till samples were collected along two 80-km long transects and to follow up on geochemical anomalies identified in 2012. Stream silt and water samples
were collected from 85 sites in northern NTS 76I and 7 sites in 76H as a followup to a 2012 survey. |
