Carbonate platform

Many biotic carbonate platforms of the northern hemisphere western Tethys drowned or shifted to non-skeletal platforms during the early Toarcian. However, southern hemisphere records of Toarcian carbonate platforms are rare, and thus the extent and significance of biotic platform demise during the T-OAE is unclear..

Five main tectonic phases previously proposed were recognized: (1) Late Triassic–Jurassic rifting between South and North America that led to the formation of the proto-Caribbean plate; this event is interpreted as half grabens controlled by fault family 1 as the east-northeast–south-southwest–striking faults; (2) Middle–Late Jurassic ...The Oligocene-Miocene is a key interval that was characterized by a cooling trend associated with a progressive decrease of atmospheric CO 2 concentrations that ends in the Present days.. In the Central Mediterranean area, during this interval, three main carbonate platform domains developed in the foreland zone of the Apennines: the Latium-Abruzzi-Campana and Apulia domain in the central and ...

The study area is located in the Interior Fars Province, one of the six subdivisions of ZFTB, southwestern Iran and northeastern part of the Arabian Plate (see Alavi 2004, 2007) (Fig. 1).During the Middle Cretaceous, this part of the Arabian Plate was a widespread shallow carbonate platform with some intra-shelf basins on the …The terms carbonate platform and carbonate shelf are often used synonymously for both modern sediments and ancient rocks formed in this environment: attached carbonate platforms are carbonate shelves that form around and prograde from a nearby land mass. The diagenesis of carbonate platform sediments is controlled by the original facies and mineralogy, climate, sea-level changes and burial history; these controls are clearly seen in the diagenesis ...In Developing Models and Analogs for Isolated Carbonate Platforms—Holocene and Pleistocene Carbonates of Caicos Platform, British West Indies (eds.

SEPM Core ...Isolated carbonate platforms started to develop in areas recording changes in topography during the early Quaternary (Mory, 1991; Saqab and Bourget, 2015a). Some of these platforms were controlled by structural highs (horsts) in a highly faulted region (Burgess et al., 2013). However, the ICPs in the study area have a much more complex …

Accordingly, little is known about the relative position of carbonate drifts with respect to ancient carbonate platforms, seaways and shallow passages within the context of palaeoceanography. ….

The term carbonate platform is both a stratigraphic term for thick deposits of shallow-water carbonate rocks, and is also used to describe the following different carbonate shelf morphologies (Fig. 4). The terms carbonate platform and carbonate shelf are often used synonymously for both modern sediments and ancient rocks formed in this environment:The quantification of carbonate constituents from point counts demonstrates that the Yangtze Platform at Guanling is a carbonate mud-rich system (containing up to 78% carbonate mud) that exhibits a significant drop in the proportion and diversity of skeletal content from the Upper Permian and into the Lower Triassic and a recovery in skeletal ...

Isolated carbonate platforms are common and contain significant hydrocarbon accumulations, particularly in the tectonically complex Sirt Basin in Libya. This study investigates the margin cyclicity of two carbonate stratigraphic sequences developed on an isolated carbonate platform in the NW Sirt Basin using 3-D post-stack seismic volume and ...One singularity of carbonate platforms is that they can drown, that is, the platform top can be submerged below the photic zone; in that case, the platform cannot catch up to sea-level and the carbonate production is irreversibly shut down (Schlager, 1981, Schlager, 1999a, Schlager, 1999b, Hallock and Schlager, 1986). The geometry and facies of ...
