Abstract:
In the Cretaceous Tuxpan-Tecolutla carbonate platform in the subsurface of the Gulf of Mexico, sedimentologic and stratigraphic data were obtained from the study of 35 wells drilled in the El Abra Formation both onshore (Golden Lane and central platform) and offshore.
Three main depositional complexes are recognized: lagoon, reefal environment, and oolitic banks. Each complex includes several microenvironments.
Dolomitization proceeded episodically in the lagoon. The last phase, showing a northern displacement of the central depression, was associated with the formation of evaporites. Several bentonitic beds are interlayered with the generally massive limestone of the El Abra Formation; some could be traced laterally and are used as marker beds for El Abra deposition.
