Book excerpt: Utilizing 887 kilometers of multi-stacked seismic reflection profiles and data from 27 exploratory wells, five salt domes arranged along two intersecting salt ridges, bounding and separating localized depocenters, were delineated by subsurface mapping of the structure, sediment distribution, and major sand trends of a 1621 square kilometer area on the Louisiana continental shelf. Pervasive normal faulting in the study area developed to accommodate lengthening of sedimentary units resulting from relative vertical displacement caused by uneven deposition and salt dome growth. These faults are domal (crestal and radial), bounding, and transverse in geometry. The genesis of the bounding faults can be visualized by two models; hinge faulting and collapse faulting. The dominant structural features of the study area began developing in early Pliocene. These features developed coincident with, and as the result of, a huge influx of paralic sediments associated with the progradation of the shelf edge across the study area between early Pliocene and early Pleistocene. The two major dip-oriented sand trends within this sediment wedge represent high constructive delta systems. The positions of the two systems were locally controlled by growing salt structures and sediments were therefore concentrated in the evolving depocenters . A hint of the deep structure which predated the influx of paralic sediments in Pliocene and early Pleistocene is revealed by a structural reversal present on seismic profiles at about 4.0 seconds in the northwest part of the study area. Reconstruction of the paleostructure of this area reveals the flank of an ancestral structural and stratigraphic basin. This basin may represent an ancestral depocenter which began developing very early on the abyssal plain.

This book was released on 1977 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: Regional investigation of late Quaternary deposits on the outer Louisiana shelf indicated two principle structural provinces: (1) a western province between West Cameron and Ship Shoal Areas which is highly faulted and structurally controlled by salt tectonics; and (2) an eastern province occupying South Timbalier and Grand Isle Areas which is greatly influenced by the effects of tectonics and sedimentation associated with the Old Mississippi Canyon complex. Vertical forces due to a mobile salt layer at depth, continual basin subsidence, and the incompetence of the overlying sedimentary strata dominate the western structural province where the main locus of deposition was located during Pleistocene time. Growth faults, post-depositional faults, salt dome faults (Radial and peripheral), grabens, horsts, and collapse faults are found in the western province; movement along several of these faults is occurring at the present. In the eastern province little deformation is apparent in the late Quaternary section where thick accumulations of recent sediments are deposited. Thick regional sands are widely distributed across the outer Louisiana shelf. These sands represent fluvial-deltaic sediments that were initially deposited in a series of coalescing deltas during low stands of sea level. As sea level rose these sands were subsequently transported to the north and laterally spread across large areas. Transgressive bars formed during intermittent halts in sea level rises.

This book was released on 2012-12-06 with total page 1063 pages. Available in PDF, EPUB and Kindle. Book excerpt: The explosion of interest, effort, and information about the ocean since about 1950 has produced many thousand scientific articles and many hun dred books. In fact, the outpouring has been so large that authors have been unable to read much of what has been published, so they have tended to concentrate their own work within smaller and smaller subfields of oceanog raphy. Summaries of information published in books have taken two main paths. One is the grouping of separately authored chapters into symposia type books, with their inevitable overlaps and gaps between chapters. The other is production of lightly researched books containing drawings and tables from previous pUblications, with due credit given but showing assem bly-line writing with little penetration of the unknown. Only a few books have combined new and previous data and thoughts into new maps and syntheses that relate the contributions of observed biological, chemical, geological, and physical processes to solve broad problems associated with the shape, composition, and history of the oceans. Such a broad synthesis is the objective of this book, in which we tried to bring together many of the pieces of research that were deemed to be of manageable size by their originators. The composite may form a sort of plateau above which later studies can rise, possibly benefited by our assem bly of data in the form of new maps and figures.

This book was released on 1985 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plio-Pleistocene sediments and rocks beneath the Louisiana and adjacent Texas shelves are the youngest of several thick packages of terrigenous sediment which prograded into the Gulf of Mexico during the Cenozoic. Comparison of diagenesis in these young sediments (more than 300 samples from 45 wells on the Louisiana-Texas shelf) to diagenesis of older Cenozoic rocks at similar burial depths elsewhere along the Gulf margin confirms that diagenesis is not strictly analogous among the various Cenozoic units. There has been an evolution of diagenesis during filling of the Gulf of Mexico. Differences in diagenesis cannot be attributed to differences in bulk mineralogy of the sands because PIio-Pleistocene sands are lithic arkoses and feldspathic litharenites with essentially the same QFR proportions as observed in subsurface Eocene and Oligocene sandstones along the Texas coast. Unaltered plagioclase is slightly more calcic (average An 24) than unaltered plagioclase in the older rocks. Burial diagenesis in Plio-Pleistocene sediments has involved essentially the same processes as observed in the older rocks, but overall, diagenesis has advanced to a lesser degree at any given depth. Cementation by quartz and carbonate, dissolution of potassium-feldspar and heavy minerals, albitization of plagioclase, and the transformation of smectite to illite have occurred in Plio-Pleistocene sediments, but cements and altered grains are not volumetrically significant shallower than 4 to 4.5 km. The temperature at which reaction of detrital constituents begins (approximately 90° C) is similar to that observed elsewhere in the Gulf, but the zone of reaction is spread over a greater depth range. The similar temperatures observed for the advent of detrital reactions across the Gulf basin suggest that these processes are more highly dependent upon temperature than upon time and that differences observed among the various units may be attributed, at least in part, to variations in the geothermal gradient. The degree of detrital grain alteration observed in these young sediments shows that significant loss of provenance information occurs quite early in the burial history. Alteration in the deep subsurface is very effective in modifying the primary detrital assemblage.
