MODULE 2: SOUTHEASTERN BASINS

PETROMEXBAS Module 2 outline and location of rock sampling sites

The Module 2 addresses the geology and hydrocarbon systems of the Southeastern Mexican basins.  The key element of this Module, as well as the Modules 3, 4, & 5 will be the extensive filed work and sampling of rock exposures, including Mesozoic rocks in the deformed Sierra Madre foreland region and Cenozoic rocks exposed within the basin itself. We will acquire a representative collection of source, reservoir and seal rocks that will be high-graded for a series of analytical studies such as RockEval, organic matter geochemistry, U, Th, and He isotopic composition, U-Pb detrital zircon geochronology, Apatite and Zircon fission track studies,  and some other. The analytical program will be developed to obtain as best constrained results as possible on source rock composition and thermal history, as well as on reservoir rocks provenance and quality.
