Abstract(unpublished)
Foreword
The Geo-mapping for Energy and Minerals (GEM) program is laying the foundation for sustainable economic development in Northern Canada. 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, the GEM program successfully carried out 14 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.
Summary(Plain Language Summary, not published)
This open file report presents a summary of 2015 work in the northwestern Cordillera (NW BC and SW Yukon) that was focused on establishing constraints on major crustal breaks within and between two major geological terranes. Field work was carried out in the Mount Nansen ¿ Nisling River area of SW Yukon, and in the Stewart River area of west central Yukon. Representative rock samples collected, and some samples were collected for specific analysis for geochemical signatures, and age dating that will help generate new tectonic models of the northern cordillera, and help guide mineral exploration for structurally hosted gold targets. Sections of the report give updates on the study of a younger sedimentary sequence of rocks that provide timing constraints on the later part of the tectonic evolution of the Yukon, as well as a reinterpretation of existing geophysical data to provide constraints on structures in the lower crust of the Canadian Cordillera.
