Testing local and extraregional sediment sources for the Late Cretaceous northern Nanaimo Basin, British Columbia, using 40Ar/39Ar detrital K-feldspar thermochronology

Detrital K-feldspar 40Ar/39Ar thermochronology was conducted on clastic sedimentary rock samples collected from northern exposures of the Upper Cretaceous Nanaimo Group on Vancouver Island and adjacent Gulf Islands of British Columbia to constrain the denudation history of the local Coast Mountains...
