Summary(Plain Language Summary, not published)
Sedimentary basins can host numerous types of mineral and petroleum deposits and temperature history is a key parameter for assessing and exploring for these resources. Multi-kinetic apatite fission track thermochronology is a state-of-the-art technique for reconstructing the thermal history of sedimentary basins. It exploits the composition-dependent temperature sensitivity of AFT parameters to resolve more details of the thermal history than the conventional methods currently used. New methods of data interpretation and modelling have been developed at GSC Calgary and are being applied to the study of northern Canadian basins where multi-compositional apatite grains are common in sedimentary rocks like sandstone. This report discusses some of the procedures that are used and presents AFT thermal modelling results for an example in the northern Yukon.
