Geochronology of the south-central Paleoproterozoic Wopmay Orogen, northwestern Canadian Shield

South-central Wopmay Orogen, between 64°N and 65°N latitude, is the focus of a bedrock mapping project by the Northwest Territories Geoscience Office in collaboration with the Geological Survey of Canada and university partners. As part of the mapping, geochronological investigations provide new U-Pb zircon crystallization ages and detrital zircon data that further constrain the timing of major events during the evolution of Wopmay Orogen.
