Application to the thermal history of the Peace River Arch Region, Western Canada sedimentary basin

Forty-seven drillcore samples from the Peace River Arch Region, Western Canada sedimentary basin were subjected to apatite fission track (AFT) analysis. The time-temperature data from measured AFT parameters were derived using the controlled random search algorithm. Results reveal regionally consistent coherent paleotemperature field in the samples. Results also suggest that the paleotemperatures are due to thermal disturbances in the region during the end of the Laramide Orogeny.
