The thermal history of hydrocarbon bearing basins is of great interest to the oil and gas industry because it pertains to organic maturation, but also to the relative timing of cementation and fluid flow through the reservoir.

This project's main objective is to investigating the feasibility of combining clumped isotope temperatures obtained from carbonate phases with absolute dating methods using radiometric isotopes.

The target for our work are carbonate atolls from the Pacific Ocean, where deeply buried Jurassic and Cretaceous carbonate lithologies have been recovered. We intend to test various radiogenic parent/daughter isotope systems in order to select the most appropriate one to obtain absolute dates for a range of carbonate minerals. If succesful, this project will open up the possibility of combining clumped isotopes temperatures with absolute geological ages, in order to build a well-constrained thermal history curve.
