Geological Survey of Canada, open file ; 8254 Includes bibliographical references. "This Open File presents new SHRIMP (Sensitive High-Resolution Ion Microprobe) zircon U–Pb geochronological results for twenty-one plutonic samples in the southern part of the Rae craton (Northwest Territories). Detailed mapping and sampling for U–Pb geochronology (two field seasons: 2015 and 2016) was carried out in collaboration with the NTGS as part of Natural Resources Canada’s Geomapping for Energy and Minerals (GEM2) program South Rae project. Samples have been collected from ten tectono-metamorphic domains recognized in the South Rae to unravel key age relationships and place time constraints on the geologic evolution of the domains. The results are integrated and compared with published data for the same area"--Introd., p. 3. gccst Geochronology gccst Geophysics Regis, Daniele. Canada. Natural Resources Canada.
