ProgramGEM2: Geo-mapping for Energy and Minerals Western Cordillera
Released2021 11 25
AbstractGeological Survey of Canada Bulletin 610 summarizes some significant research results and future directions from twelve years of field-based research in the northern Cordillera. The Bulletin presents five distinct, stand-alone, thematic sections: 'Oceanic terranes'; 'Pericratonic Yukon-Tanana terrane'; 'Cordilleran magmatism'; 'Overlap assemblages'; and 'Geophysical characteristics'. These papers are not intended to provide an exhaustive summary of all research that was carried out over the course of GEM; however, these themes, along with individual activity results, provide a good starting point for evaluating future research directions in the northern Cordillera.
Summary(Plain Language Summary, not published)
This Bulletin presents highlights of the research on the Yukon-Tanana terrane carried out under the auspices of the Cordillera project, Geo-mapping for Energy and Minerals program. The GEM-2 Cordillera project (2014-2020) aimed to generate new geoscience knowledge of bedrock geology, regional tectonic history, and crustal architecture to support land use and exploration decisions. It involved multidisciplinary field-based activities including framework mapping, thematic studies, and geological analyses focused on areas with insufficient knowledge in western and southern Yukon and northern British Columbia.
