Book Description
Numerous isolated carbonate platforms developed in the Central Luconia Province of offshore Sarawak (during Middle to Late Miocene time). Fault-bounded highs produced largely by extensional deformation and later overprinted by strike-slip deformation provided substrates for the platforms and affected their growth histories. Flooding of these structural highs at ~16.5 Ma initiated carbonate sedimentation nearly simultaneously across the area. Later, third-order sea-level fluctuations and extrinsic factors such as differential subsidence, paleowind patterns and siliciclastic influx then controlled the internal architecture of the platforms. 2-D regional seismic lines, publicdomain data and published literature were used to analyze growth patterns and demise of carbonate platforms across the study area. Five Growth Stages were recognized in the carbonate platforms based on seismic facies analysis and stratigraphic relationships between reflectors. Platforms from the southeastern part of Central Luconia are thicker and larger than platforms located toward the central and northwestern areas, which reflect greater long-term tectonic subsidence to the southeast. Additionally, northwestward prograding siliciclastic sediments from mainland Borneo caused additional flexural subsidence in the eastern part of the area and environmental deterioration for platforms located beyond the range of active siliciclastic sedimentation. Both of these factors reduced the growth potential of platforms and thus subdued carbonate development. Platform termination was regionally diachronous and was produced in two steps. The first platforms drowned (~12.5-9.7 Ma) were in the eastern parts of the study area which were affected by incoming siliciclastic sediments and high local subsidence. Platforms drowned later (~6.3-5.5 Ma) were caused by a rapid sea-level rise combined with an intense local subsidence. Carbonate accumulation rates were measured between intraplatform markers, resulting in a trend that indicates a decrease in sedimentation rate with the square root of time. Comparisons between Central Luconia carbonates and age-equivalent carbonate platforms elsewhere in East Natuna Basin showed that Central Luconia carbonate platforms were drowned earlier (latest late Miocene time) than East Natuna carbonate platforms (Early Pliocene time).

Book Description
Modern seismic data have become an essential toolkit for studying carbonate platforms and reservoirs in impressive detail. Whilst driven primarily by oil and gas exploration and development, data sharing and collaboration are delivering fundamental geological knowledge on carbonate systems, revealing platform geomorphologies and how their evolution on millennial time scales, as well as kilometric length scales, was forced by long-term eustatic, oceanographic or tectonic factors. Quantitative interrogation of modern seismic attributes in carbonate reservoirs permits flow units and barriers arising from depositional and diagenetic processes to be imaged and extrapolated between wells. This volume reviews the variety of carbonate platform and reservoir characteristics that can be interpreted from modern seismic data, illustrating the benefits of creative interaction between geophysical and carbonate geological experts at all stages of a seismic campaign. Papers cover carbonate exploration, including the uniquely challenging South Atlantic pre-salt reservoirs, seismic modelling of carbonates, and seismic indicators of fluid flow and diagenesis.

Book Description
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.

Book Description
The Cenozoic carbonate systems of Australasia are the product of a diverse assortment of depositional and post-depositional processes, reflecting the interplay of eustasy, tectonics (both plate and local scale), climate, and evolutionary trends that influenced their initiation and development. These systems, which comprise both land-attached and isolated platforms, were initiated in a wide variety of tectonic settings (including rift, passive margin, and arc-related) and under warm and cool-water conditions where, locally, siliciclastic input affected their development. The lithofacies, biofacies, growth morphology, diagenesis, and hydrocarbon reservoir potential of these systems are products of these varying influences. The studies reported in this volume range from syntheses of tectonic and depositional factors influencing carbonate deposition and controls on reservoir formation and petroleum system development, to local studies from the South China Sea, Indonesia, Kalimantan, Malaysia, the Marion Plateau, the Philippines, Western Australia, and New Caledonia that incorporate outcrop and subsurface data, including 3-D seismic imaging of carbonate platforms and facies, to understand the interplay of factors affecting the development of these systems under widely differing circumstances. This volume will be of importance to geoscientists interested in the variability of Cenozoic carbonate systems and the factors that controlled their formation, and to those wanting to understand the range of potential hydrocarbon reservoirs discovered in these carbonates and the events that led to favorable reservoir and trap development.
