| Summary | (Plain Language Summary, not published)
This Open File presents new SHRIMP (Sensitive High-Resolution Ion Microprobe) U-Pb zircon geochronological results for fifteen plutonic samples from the
Nonacho Lake area along the western margin of the Rae craton (Northwest Territories). Detailed mapping and sampling for U-Pb geochronology was carried out by Northwest Territories Geological Survey (NTGS) and academic partners as part of the 'Nonacho
Bedrock Mapping Project' during the 2018-2020 field seasons. Samples have been collected from the Nonacho basement to unravel key age relationships between units, place time constraints on the geologic evolution of the southwestern Rae margin, and
assess its mineral potential. |
