The Basins, Orogens and Evolution of the Southern Gulf of Mexico and Northern Caribbean
CONTAINS OPEN ACCESS
This volume brings together 17 comprehensive, data-rich analyses to provide an updated perspective on the Mexican sector of the Gulf of Mexico, Florida and the northern Caribbean. The papers span a broad range of scales and disciplines from plate tectonic evolution to sub-basin-scale analysis. Papers are broadly categorized into three themes: (1) geological evolution of the basins of the southern Gulf of Mexico in Mexico, Bahamas and Florida and their hydrocarbon potential; (2) evolution of the region's Late Cretaceous to Neogene orogens and subsequent denudation history; and (3) geological evolution of the basins and crustal elements of the northern Caribbean. This book and its extensive datasets are essential for all academic and exploration geoscientists working in this area. The volume also includes two large maps detailing the Mexican Gulf of Mexico and the Northern Caribbean areas.

The structural evolution of southern Mexico is described in the context of its plate tectonic evolution and illustrated by two restored crustal scale cross-sections through Cuicateco and the Veracruz Basin and a third across Chiapas. We interpret the Late Jurassic–Early Cretaceous opening of an oblique hyper-stretched intra-arc basin between the Cuicateco Belt and Oaxaca Block of southern Mexico where Lower Cretaceous deep-water sediments accumulated. These rocks, together with the hyper-stretched basement beneath them and the Oaxaca Block originally west of them, were thrust onto the Cretaceous platform of the Cuicateco region during a Late Cretaceous–Eocene orogenic event. The mylonitic complex of the Sierra de Juárez represents this hyper-stretched basement, perhaps itself an extensional allochthon. The Chiapas fold-and-thrust belt is mainly Neogene in age. Shallowing of the subduction angle of the Cocos Plate in the wake of the Chortis Block, suggested by seismicity and migrating arc volcanism, is thought to play an important role in the development of the Chiapas fold-and-thrust belt itself, helping to explain the structural dilemma of a vertical transcurrent plate boundary fault (the Tonalá Fault) at the back of an essentially dip-slip fold-and-thrust belt.
