Research Advances of the Precambrian and Paleozoic Evolution of the Basement of the Northern Sierra Madre Oriental, Mexico: Huizachal-Peregrina Anticlinorium

Abstract

In the last years the knowledge of the geological history of the pre-Mesozoic units that conform the basement of the Laramidic Sierra Madre Oriental (SMO) have been rapidly enriched. The development of sedimentary basins, magmatic arcs, rifting, collisions, accretions, metamorphism, and orogenies during Precambrian and Paleozoic times are important events for the assembly of the geological puzzle of northeastern Mexico. The study of the units outcropping in the eroded core of the Huizachal-Peregrina allows the reconstruction of these processes preserved and established in the northwest margin of Gondwana before the dismembering of Pangaea during the Early Mesozoic. More detailed work is needed to characterize and reconstruct the Paleozoic Tamatán Basin that remained free of metamorphism in comparison to the contemporaneous accretion prism bordering Gondwana. This issue is of high importance for the study of hydrocarbon potential of Paleozoic sequences of the circum-Gulf of Mexico.
