Volume 3 of Gulf of Mexico Origin, Waters, and Biota; a series edited by John W. Tunnell Jr., Darryl L. Felder, and Sylvia A. Earle A continuation of the landmark scientific reference series from the Harte Research Institute for Gulf of Mexico Studies, Gulf of Mexico Origin, Waters, and Biota, Volume 3, Geology provides the most up-to-date, systematic, cohesive, and comprehensive description of the geology of the Gulf of Mexico Basin. The six sections of the book address the geologic history, recent depositional environments, and processes offshore and along the coast of the Gulf of Mexico. Scientific research in the Gulf of Mexico region is continuous, extensive, and has broad-based influence upon scientific, governmental, and educational communities. This volume is a compilation of scientific knowledge from highly accomplished and experienced geologists who have focused most of their careers on gaining a better understanding of the geology of the Gulf of Mexico. Their research, presented in this volume, describes and explains the formation of the Gulf Basin, Holocene stratigraphic and sea-level history, energy resources, coral reefs, and depositional processes that affect and are represented along our Gulf coasts. It provides valuable synthesis and interpretation of what is known about the geology of the Gulf of Mexico. Five years in the making, this monumental compilation is both a lasting record of the current state of knowledge and the starting point for a new millennium of study.

The selected bibliography is a product of an extensive literature search. The preponderance of the references selected have been published since 1950. The publications deal principally with the Marine Environment, however, a number of them apply to Terrestrial Geology and Geophysics peripheral to the Gulf. (Author).

Borehole geophysics is frequently applied in hydrogeological environmental investigations where, for example, sites must be evaluated to determine the distribution of contaminants. It is a cost-effective method for obtaining information during several phases of such investigations. Written by one of world's leading experts in the field, A Practical Guide to Borehole Geophysics in Environmental Investigations explains the basic principles of the many tools and techniques used in borehole logging projects. Applications are presented in terms of broad project objectives, providing a hands-on guide to geophysical logging programs, including specific examples of how to obtain and interpret data that meet particular hydrogeologic objectives.

The formation of the Gulf of Mexico (GoM) relates to the breakup of Pangea and opening of the central Atlantic Ocean. The tectonic history of the basin is still being debated due to lack of geological constraints. This project addresses the crustal architecture in the northeastern GoM from integrative analysis of multiple geophysical datasets to provide constraints for the tectonic reconstruction.The objectives of this study are: 1) to delineate various tectonic zones (continental and oceanic domains) and map the boundary between them, 2) to derive physical properties of the subsurface rocks, 3) to map the major tectonic structures in the study area, such as the pre-salt basin and the Seaward Dipping Reflectors (SDR) province in continental domain, and segments of an extinct spreading center with associated transform faults in oceanic domain, and 4) to establish the spatial and temporal relations between different tectonic zones and structures. Three two-dimensional subsurface models were developed in the northeastern GoM by using consistent physical properties for subsurface rocks. Further, spatial analysis was performed on gravity and magnetic grids, which allowed mapping of various tectonic zones and structures. As a result of this study, two distinct spreading episodes of GoM formation were identified. The first one, presumably from 160 to 150 Ma, was an ultra-slow spreading event (estimated full spreading rate of 0.9 cm/yr) that produced thin (~5 km) and dense (2.95 g/cc) oceanic crust with fast seismic velocities (~7km/s) and high magnetic susceptibility (0.0075 cgs), most likely composed of gabbro. At ~150 Ma, the spreading center jumped to the south due to a change in location of the Euler pole. The second spreading episode was faster (1.1 cm/yr) and produced thicker crust (up to 9 km) composed of two layers – a basaltic layer (2-4 km thick, Vp = 6-6.5 km/s, density 2.65 g/cc and magnetic susceptibility 0.007 cgs) on top of a gabbroic one. The ridge propagation resulted in the asymmetry of the oceanic domain that needs to be accounted for during tectonic reconstruction.
