Rhenium-osmium geochronology and oil-source correlation of the Duvernay petroleum system, Western Canada sedimentary basin: Implications for the application of the rhenium-osmium geochronometer to petroleum systems

摘要

The Re-Os geochronometer has been applied to many petroleum systems worldwide. However, it is debated if the Re-Os systematics in petroleumactually record the timing of oil generation. Here, we investigate the Re-Os isotope systematics of the Duvernay petroleum system in the Western Canada sedimentary basin, which has been shown to be a relatively simple petroleum system that is associated with oil generated during the Late Cretaceous-early Eocene Laramide orogeny from a single source.
