textThe stratigraphic relationship of Lower Cretaceous rocks in northern Mexico is poorly understood because they have not been studied in detail. One of the main objectives of this study is to analyze the Lower Cretaceous stratigraphy in northwestern Coahuila and to establish the relationships of the rocks with those of Trans-Pecos Texas. The present study comprises the lithostratigraphy and biostratigraphy of the seventeen formational units that constitute the Lower Cretaceous in northwestern Coahuila. Based on this information, paleogeographic reconstructions show the major stages of these events. The Lower Cretaceous rocks in northwestern Coahuila represent two major depositional cycles. The first extended from Neocomian to Late Aptian ...
