Available in PDF, EPUB and Kindle. Book excerpt: Combining field research of outcrop geology and investigating the recent formation of carbonate rocks in coastal environments the author gives an introduction in sequence stratigraphy. Using computer simulations the book focuses on four questions, regarding the geometry of carbonate wedges, sequences comparable with geotectonic cycles, their influence by geoidal pulses and the determination of these geoidal pulse distribution in geological time. Examples from the Alps and Florida show that ramps and divergent patterns, megabreccias, drowning of carbonate platforms etc. are results of global short-term sea level falls, interpreted as geoidal eustasy. This volume will be a fruitful supplement for the interpretation and understanding of sequence stratigraphic sections not only for scientists and students but also for researchers in the oil andgas industry.

This book was released on 2012-12-06 with total page 378 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume arises from the NATO Advanced Research Workshop (ARW) on 'North African Cretaceous rudist and coral formations and their contributions to carbonate platform development , which was held in Tunisia, on 13-18 May, 2002. It was convened by M. El Hedi Negra (Universite 7 Novembre de Carthage, now Universite de Tunis El Manar, Tunisia) and Eulalia Gili (Universitat Autonoma de Barcelona, Spain). The aims of the ARW were: (1) to review and critically assess currently available data on rudist/coral formations in North African Cretaceous carbonate platforms, and their correlations, and to integrate these data with other studies around the Mediterranean; (2) to place the findings in a global context, noting both similarities with other regions of platform development as well as local differences, and (3) exploring possible reasons for these; and to help promote the creation of a vibrant peri-Mediterranean collaborative research community, embracing researchers from the entire region, to carry forward this ambitious research programme. Twenty-two presentations (oral and poster) provided both topical reviews (covering rudist evolution, and ecology, mineralogical changes, applications of strontium isotope, and graphic correlation methods, and platform typology) as well as regional syntheses (Tunisian reservoirs, Moroccan platform history, Tunisian platforms and rudist/coral facies, Algerian platforms, and Egyptian platforms). Fifteen of these presentations are expanded here as papers. The workshop was attended by 24 academic staff, 4 geologists from the oil industry, plus several observers and students.

This book was released on with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Modern shallow-water carbonate systems commonly display a complex pattern of juxtaposed depositional environments with a patchy facies distribution (facies mo saics). On ancient carbonate platforms, the reconstruction of lateral facies distribution is often hampered not only by discontinuous outcrop but also by lack of suffi ciently high time resolution. This case study from the Oxfordian (Late Jurassic) of the Swiss Jura Mountains demonstrates a way to improve the temporal and spatial resolution for the interpretation of carbonate rocks. Sequence-stratigraphic and cyclostratigraphic analyses have been performed that provide a basis for defi ning depositional sequences, which formed through sea-level changes that were induced by the 400-, 100- and 20-kyr orbital cycles. On the 100-kyr scale, sequence boundaries are well developed and can be correlated between sections. However, identifi cation and correlation of sequences related to the 20-kyr cycle may be diffi cult if local processes overprinted the record of orbitally controlled sea-level changes. The reconstruction of facies distribution along selected time lines gives a dynamic picture of platform evolution with time steps of a few ten thousand years and helps to interpret the controlling factors such as differential subsidence, low-amplitude eustatic sea-level fl uctuations, climate and ecology of the carbonate-producing organisms. Reefs and ooid shoals developed preferentially on topographic highs and thus accentuated platform morphology. Siliciclastics were shed onto the platform during sea-level falls and increased rainfall in the hinterland; their distribution was controlled by platform morphology. Siliciclastics and associated nutrients hindered carbonate production and thus indirectly infl uenced platform morphology. In addition to these controls, random processes acted on the smaller-scale facies relationships. Sedimentation rates can be estimated for each facies type over time spans of 10- 0 kyr. They.

This book was released on 1998-09-17 with total page 216 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 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.

Available in PDF, EPUB and Kindle. Book excerpt: This special publication Perspectives in Carbonate Geologyis a collection of papers most of which were presented at asymposium to honor the 80th birthday of Bob Ginsburg at the meetingof Geological Society of America in Salt Lake City in 2005. Themajority of the papers in this publication are connected with thestudy of modern carbonate sediments. Bob Ginsburg pioneered theconcept of comparative sedimentology - that is using the modern tocompare to and relate to and understand the ancient. These studiesare concerned with Bob's areas of passion: coral reefs andsea-level; submarine cementation and formation of beach rock;surface sediments on Great Bahama Bank and other platforms; originof ooids; coastal sediments; formation of stromatolites; impact ofstorms on sediments; and the formation of dolomite. The remainderof the papers apply the study of modern environments andsedimentary processes to ancient sediments.
