Marine sedimentary rocks of the Mexican geosyncline, including neritic platform and bathyal zones, have a volume of 1,325,000 cu km and a potential reserve of 14,310 million bbl of oil which possibly formed in Cretaceous and Jurassic strata. Igneous activity and locally intense structural deformation of north-central Mexico did not necessarily affect migration and accumulation of petroleum. The area enclosing the Coahuila peninsula, southward to San Luis Potosi and westward to the Sierra Madre Occidental, must be explored geologically in more detail. Ancient neritic zones have the best possibilities for commercial petroleum accumulation.
