Includes bibliographical references (pages 72-73). "This Open File presents new ⁴⁰Ar/³⁹Ar hornblende and biotite analyses for forty-six plutonic and pelitic samples in the southern part of the Rae Craton, Northwest Territories (NWT). Detailed mapping and sampling for ⁴⁰Ar/³⁹Ar thermochronology was carried out as part of Natural Resources Canada's Geomapping for Energy and Minerals (GEM-II) South Rae project. Age determinations were carried out in the Geological Survey of Canada (GSC) Noble Gas Laboratory facility in Ottawa, Ontario. Samples have been collected from different tectonometamorphic domains recognized in the South Rae (during three field seasons: 2012, 2015, and 2016) in order to (i) delineate domains of different cooling histories and (ii) improve our understanding of the age of regional metamorphism and exhumation of the South Rae Craton. These data will be used in the future to examine the role of major structures and shear zones in accommodating the exhumation of different blocks, as well as the role of major crustal shear zone as conduits for transporting mineralized fluids"--Introduction, page 3. gccst Geology gccst Geochronology Kellett D.
