ABSTRACT
The geological history of Mexico shows that there has been three events that were suitable for the development and formation of coal beds. The first event happened from the Upper Triassic to Middle Jurassic Epochs (200-170 Ma); the second event of favorable geologic conditions took place at the end of the Late Cretaceous Epoch during the Maestrichtian age (75-65 Ma); and the last third event happened during the Eocene Epoch, Lutetian-Bartonian Age (50-40 Ma).
