Download or read book Carbonate Depositional Systems Assessing Dimensions and Controlling Parameters written by Hildegard Westphal and published by Springer Science & Business Media. This book was released on 2010-08-05 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: Carbonate sediments are of increasing relevance for archives of past environmental conditions and for economical reasons in areas of geothermal energy and hydrocarbon reservoirs. Complex interaction of physical and chemical parameters with biological parameters determines the architecture and composition of carbonate sedimentary bodies. This book closes some of the still existing gaps in our understanding of the influence and interplay of physical, chemical, and biological parameters with carbonate sedimentation. An understanding of this interaction is not only required for reliable prediction of reservoir quality but also for a robust interpretation of environmental conditions in the past and the present. It is written by geologists for geologists in order to provide an easily accessible overview of the large amount of relevant information provided by the neighbouring sciences. The approach of the book is to document the modern depositional environments of three classical areas of carbonate deposition, each characteristic for a specific sedimentological setting (isolated platform, attached shelf, ramp) in order to assess both the range of physical, biological and chemical parameters and their sedimentary response. This book presents a comprehensive compilation based on data from published work and unpublished theses, and the integration of these data in order to extract previously undiscovered relationships between the discussed parameters and carbonate deposition.

This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation explores the influence of the environment on the lateral spatial patterning of facies in modern isolated carbonate platforms through six studies. The first study describes the creation of a database of benthic habitat and bathymetric maps derived from multispectral satellite imagery and the field data used calibrate and validate the mapping algorithms. The second study develops and assesses a new approach for remotely-deriving water depth from multispectral satellite imagery without the need for ground-truth information. The third study identifies a criterion for distinguishing between facies belts and mosaics and deploys the criterion to investigate the co-occurrence of these arrangements within modern carbonate depositional systems. The fourth study explores the geologic history of an isolated carbonate platform in the Bahamas, Cay Sal Bank, to understand why the lateral spatial pattering observed in this site differs from the patterns observed in neighboring platforms. The fifth study explores the distribution of carbonate facies in relation to wave energy and water depth for two detached ramps in the Red Sea, Ras Al-Qisbah and Al Wajh. The last study investigates the recovery of scleractinian communities along the coasts of two islands in the Galapagos archipelago, Darwin and Wennman (Wolf) Islands, following a large-scale disturbance in the 1980s. Together, these six studies provide new insight into the spatial patterning of facies within modern carbonate depositional systems and the influence of the environment on the observed arrangements.
Download or read book Carbonate Platform Slopes A Record of Changing Conditions written by Hildegard Westphal and published by Springer. This book was released on 2008-01-03 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: Periplatform slope sediments from the Bahamas serve as an example for a small-scale sedimentologic record of environmental changes. Carbonate platforms react sensitively to sea-level fluctuations. Therefore, sediments deposited on the slope during lowstands differ in composition from highstand deposits. A second focus is the early diagenetic alteration and cementation of these sediments with their high diagenetic potential. This book contributes to and discusses new developments in carbonate sedimentology such as the concepts of highstand shedding and early burial diagenesis, which also have an impact on reservoir studies.

This book was released on 2001 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume will be of special interest to carbonate sedimentologists, geochemists, petroleum geologists, engineers, and seismologists. It addresses fundamental aspects of prograding carbonate platforms in a Neogene example from Great Bahama Bank. A remarkable seismic profile, which imaged the prograding margin, provided the seismic stratigraphic framework. Two continuouslycored and logged borings on the profile produced the ground truth for testing and characterizing processes: lithologies and ages of sequence boundaries; influence of sea level fluctuations on progradation, controls on impedance contrasts in carbonates; fluid flow through the submerged margin; log responses of different lithologies; and the origin, ages and depositional environments of the platform top and prograding clinothems. The new findings on diagenesis are of special interest, including complete mineral stabilization in seawater, early burial dolomitization related to sequence boundaries and how diagenesis controls sonic velocity and permeability.

This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Isolated carbonate platforms can provide substantial hydrocarbon reservoirs because they develop significant depositional relief and are commonly buried by relatively impermeable basin-filling sediments. Consequently, there is ongoing interest in the mechanisms that control their morphology and facies distributions. Because the deposition of carbonate sediments is influenced by a complex interaction of environmental conditions that vary both temporally and spatially across depositional systems, the relative importance of controls on platform morphology is difficult to constrain. The key to developing a better understanding is to recognize causal links between changes in oceanographic conditions and variability in resulting geometries. Unfortunately, most studies of exposed carbonate platforms limit the ability to discern influences beyond fluctuations in relative sea level, because they are based on a single cross section of a platform and record deposition during periods of relative stasis in ocean chemistry and biotic evolution. In this study, however, I examined cross-sectional exposures from three geographic sectors of the Late Permian to Late Triassic Great Bank of Guizhou (GBG) in the Nanpanjiang Basin of south China. Deposition on the GBG spanned the tumultuous transition from Paleozoic to Mesozoic oceans, providing a rare opportunity to evaluate the influence of changes in carbonate factory type during a period of significant global change. In addition, I compared multiple exposures of the platform to determine the differential impact of basin-wide controls such as external sediment supply and antecedent topography on the evolution of platform geometries. The integrated analysis of satellite imagery, field mapping, chemostratigraphy, biostratigraphy and petrography shows that chemical and biological controls associated with end-Paleozoic extinction and environmental disturbance led to changes in carbonate factory type that contributed to significant temporal variability in the platform geometry. The GBG initiated with small patch reefs in the latest Permian, was dominated by microbial carbonates in the immediate aftermath of extinction, progressed to a low-relief bank with oolite shoal margins in the earliest Triassic when skeletal organisms were rare, developed a high-relief morphology with steep slopes when transport was limited by rapid cementation, and later established a reef-rimmed margin as environmental conditions allowed for the return of abundant skeletal organisms in benthic environments. In contrast, physical controls, including antecedent topography and external sediment supply, produced significant spatial variability in the GBG. In the northwestern sector, over-steepening led to the development of an erosional escarpment and bypass margin following an initial interval of Early Triassic progradation over a shallow basin floor. In the northeastern sector, a similar pattern was disrupted by Middle Triassic influx of siliciclastic sediments that raised the basin floor, reduced topographic relief, and provided a structural foundation for multiple episodes of progradation and the retention of an accretionary margin. In the southwestern sector, an adjacent deep basin established significant topographic relief, eliminating the structural support for progradation and leading to large-scale sector collapse of the platform margin. This study provides causal links between depositional environments and resulting geometries and shows that changes in carbonate factory type, differences in antecedent topography, and the pattern and timing of external sediment supply have a significant impact on the stratigraphic evolution of isolated carbonate platforms.

Download or read book Mass transport Deposits in Deepwater Settings written by R. Craig Shipp and published by SEPM Soc for Sed Geology. This book was released on 2011 with total page 532 pages. Available in PDF, EPUB and Kindle. Book excerpt: Historically, submarine-mass failures or mass-transport deposits have been a focus of increasingly intense investigation by academic institutions particularly during the last decade, though they received much less attention by geoscientists in the energy industry. With recent interest in expanding petroleum exploration and production into deeper water-depths globally and more widespread availability of high-quality data sets, mass-transport deposits are now recognized as a major component of most deep-water settings. This recognition has lead to the realization that many aspects of these deposits are still unknown or poorly understood. This volume contains twenty-three papers that address a number of topics critical to further understanding mass-transport deposits. These topics include general overviews of these deposits, depositional settings on the seafloor and in the near-subsurface interval, geohazard concerns, descriptive outcrops, integrated outcrop and seismic data/seismic forward modeling, petroleum reservoirs, and case studies on several associated topics. This volume will appeal to a broad cross section of geoscientists and geotechnical engineers, who are interested in this rapidly expanding field. The selection of papers in this volume reflects a growing trend towards a more diverse blend of disciplines and topics, covered in the study of mass-transport deposits.
