| Abstract | Geophysical data acquired under the Geological Survey of Canada's GEM Cordillera project provide a foundation to a broad range of geological investigations in the northern Canadian Cordillera. For areas
of specific geological interest, over 230 000 km of high-resolution aeromagnetic data form a mosaic of comprehensive coverage over a total area of more than 82 000 km2. The data provide a powerful and valuable legacy data set for current and future
activities by the Geological Survey of Canada and academic and industry partners and clients.
Foremost, geophysical data interpretation complements surface geological mapping, especially in inaccessible terrain where bedrock exposure is commonly
poor, enabling clearer definition of a region's geology and structure. Beyond applications to bedrock geological mapping, geophysical modelling, integrated with geological results, affords an improved understanding of the deeper crustal structure,
leading to new models of the region's tectonic development and mineral deposit context. |
| Summary | (Plain Language Summary, not published)
Geophysical results from the northern Canadian Cordilleran activities of the GEM Program (Phases 1 and 2) are summarised. Aeromagnetic surveys form the
core of the data acquired. These data are presented as well as compilations of the individual surveys to provide continuous coverage and maps of the data across the northern Cordillera. Examples are provided on the integrated strategy in use of the
data to support geological mapping, leading to improved geological maps. Regional compilation data were also used to understand the broad scale structure and plate tectonic history of the region. |
