Exploring the Tehery region : correlating supracrustal sequences using detrital zircon geochronology, Rae Craton, Nunavut / Ferderber, J., Kellett, D.A., and Wodicka, N. : M183-2/7424E-PDF

"The Tehery region, situated between Chesterfield Inlet and Wager Bay, Nunavut, is an area of the Rae craton that has been only superficially mapped. In the summer of 2012, new reconnaissance field mapping as part of the Geo-mapping Frontiers project of the Geological Survey of Canada (Geo-mapping for Energy and Minerals program) identified a number of supracrustal sequences. Regionally, supracrustal rocks of the Rae craton contain important commodities: Archean supracrustal rocks in the region host economic gold deposits (e.g. Meadowbank), and Proterozoic supracrustal rocks are exploration targets for base metals and uranium. This study compares two supracrustal packages in the Tehery region with better-studied sequences with the aim of better understanding the tectonic evolution of the Rae craton, as well as identifying the area's economic potential for future mineral exploration. Detrital zircon geochronology is used to characterize the provenance of supracrustal packages, as well as to constrain maximum deposition ages for the successions"--Introduction.
