Preliminary detrital zircon geochronology of the Neruokpuk Formation in the Barn Mountains, Yukon
Neoproterozoic to Cambrian siliciclastic rocks in the Barn Mountains, Yukon are stratigraphically similar to coeval strata on the northwest Laurentian margin and the North Slope subterrane of the Arctic Alaska terrane. Sandstone samples collected for detrital zircon U/Pb geochronology from Oldhamia-bearing sections in the Barn Mountains yield age spectra with major Paleoproterozoic and subordinate Mesoproterozoic and Archean peaks that are compatible with a Laurentian cratonal provenance. Comparison of data from the Barn Mountains with available data from the Laurentian margin is permissive of derivation from either the northwestern or the north to northeastern margin of Laurentia.
The Government of Yukon acknowledges that Indigenous Peoples have traditional territories throughout the Yukon and celebrates their role as stewards of the lands and waters and their ongoing connection to this place.
