This study integrates detrital apatite (U-Th)/He thermochronology with source rock characterization and one dimensional burial and thermal history reconstruction modeling to better understand the thermal, tectonic, and petroleum systems at Hoodoo Dome, an evaporite diapir in the Canada's hydrocarbon bearing Sverdrup Basin. Thermochronology on Lower Cretaceous rocks indicates a time of exhumation and cooling related to Eurekan deformation during the Latest-Cretaceous (80 Ma) until Middle Eocene (41 Ma). Burial history modeling of an exploration well at Hoodoo Dome (Hoodoo Dome H-37) indicates that peak hydrocarbon generation and expulsion beneath Hoodoo Dome occurred during the Aptian and Albian. Combined, these results indicate that the petroleum system below Hoodoo Dome generated and expelled its hydrocarbons prior to major structural trap formation associated with the Eurekan Orogeny. As a result, the warrant to further explore for large hydrocarbon fields associated structural traps related to the Late ...
