The MTDs in the study area were divided into three types (slide, slump ...The Valdediezma platform consists of upper Tournaisian to lower Bashkirian (Carboniferous) shallow-water carbonates deposited in the core of the Picos de Europa Province (Cantabrian Mountains, northwest Spain). Although faulted in several thrust sheets, it is the only preserved platform developed in the Mississippian starved basins of the southern branch of the Variscan Orogen that is ...The transport-production ratio is a key control on the evolution and geometry of carbonate platforms. This is the case with different production profiles (both euphotic and oligophotic) and in mixed grain-size and mixed transport-rate systems. Carbonate producing factories significantly influence the rate of sediment production, the depth ...Overall, Florida's geological history has been driven by changing sea levels, which have influenced the production of carbonate bedrock, siliciclastic input/transport, hydrology, and surface topography. During the last interglacial period, the majority of south Florida was a shallow carbonate environment with some siliciclastic input.carbonate s. When this climate is arid then high rates of evaporation and the deposition of evaporites (either supratidal or subaqueous) are a common response. . Karstification of exposed carbonate platforms may occur during sea level lowstand by rainfall in humid regions (James and of carbonate platforms on seismic data and to popu-late these in new plays with meaningful depositional. environments and conceptual reservoir potential.

A preliminary section, based on ...The Bahama shelf, or carbonate platform, mimics the setting that repeatedly prevailed across the stable cratonic areas of the major continental blocks during late Precambrian, Paleozoic, and Mesozoic time and serves as a model for explaining the various limestone types that make up such ancient carbonate successions. The edge ofABSTRACT Many types of carbonate platforms have been described, from homoclinal ramps to rimmed shelves and a full spectrum of variations in between; the distinction between these different types can be problematic. Nevertheless, classification of carbonate platforms is not just a semantic or academic issue.

From ideation to execution, we take a holistic approach to brand development and marketing, offering strategy, design, public relations, and social media services.The carbonate influence is greater in the clay minerals facies than in the quartzous facies because of the mixing of terrigenous mud (relict or modern) with modern bioclastic sedimentation. This mixed carbonate-siliciclastic system is observed throughout the semi-arid shelf of the Brazilian equatorial margin (Piauí to Rio Grande do Norte shelf).The Miocene carbonate platform was terminated by gradual drowning, showing smooth, concentric seismic reflections and forming convex mounds on the tops of the platforms. Fyhn et al. (2009b) suggested that the Phanh Rang Carbonate Platform, located offshore south Vietnam, initiated during late Middle Miocene. Following earlier Miocene carbonate ...ABSTRACT. Various types of carbonate platforms are characterized by distinctive profiles, facies, and evolutionary sequences. Ramps may be homoclinal or distally steepened, and may have fringing or barrier shoal-water complexes of ooid-pellet sands or skeletal banks. The abundance and types of reef-bearing carbonate platforms reflect the evolution of Devonian climate, with conspicuous microbial-algal reefs in the warm Early and Late Devonian and sponge-coral reefs in the cooler Middle Devonian.

Structurally, the PCP can be coincident with the top of a horst (or 'central high') block or the crestal area of a tilted block. In the latter case, the sediment surface of the PCP slopes gently (maximum ...The Bahamian carbonate platform is located in a tectonically stable passive-margin setting and the gravity-flow deposits were laid down in an environment exclusively controlled by eustatic sea-level fluctuations. This study shows that all types of gravity-induced carbonate deposits, calciturbidites, and calcidebrites, were deposited in response ...Pelagic carbonate platforms (PCPs) are submarine highs that are drowned fragments of an ancestor regional peritidal carbonate platform. PCPs can be horsts or crests of rotated blocks. The extensionalThis paper presents the facies and depositional environment of the early Miocene Dam Formation, Eastern Arabian platform, Saudi Arabia. Deposition of Dam Formation (Fm.) was considered as a restricted shallow marine deposition. Few studies suggest the role of sea-level change in its deposition but were without decisive …Most carbonate sediments originate on a shallow-water platform, shelf, or ramp and are transported landward and basinward. "Platform" is a general term for the shallow-water environment, whereas "shelf" and "ramp" refer to topography—shelves with flat platform tops and steep foreslopes and ramps having gently dipping platform tops and ...A carbonate platform is a sedimentary body which possesses topographic relief, and is composed of autochthonic calcareous deposits. Platform growth is mediated by sessile organisms whose skeletons build up the reef or by organisms (usually microbes) which induce carbonate precipitation through their metabolism. Therefore, carbonate platforms ...The insights suggest that although each platform is unique in many ways, Phanerozoic isolated carbonate platforms include numerous themes that are persistent across ages, sizes, settings, and ...The carbonate platform depositional system is sensitive to many variables, a number of which are interrelated, making it difficult to clarify how each variable affects the growth pattern of a carbonate platform. A simple computer model that simulates the carbonate platform depositional system provides an efficient means of overcoming this problem.Combined with sedimentary facies analysis, our research suggests that the demise of the Middle Jurassic carbonate platform may have been caused by terrigenous detrital inputs into the Qiangtang Basin. High-frequency sea-level fluctuations increased terrestrial inputs and carbonate production rates at the orbital scale.

Although reef construction and carbonate platform development are intimately linked today, this was not the case for most of the Phanerozoic. Carbonate production by non-enzymatic precipitation and non ...Since the origin of the carbonate platform concept, the reconstruction of the geometry and the evolution of the margin has been an intriguing topic. The Latium-Abruzzi platform is one of the largest shallow water domains of the Central Apennines, however, the reconstruction of the geometry and evolution of its margin has been classically problematic because the latter has been erased by the ...However, it is important to point out that sedimentation rates in carbonate platforms seemingly decrease with a scaling trend over an increasing interval of observation (Sadler, 1981;Enos, 1991 ...Standard carbonate facies models are widely used to interpret paleoenvironments, but they do not address how carbonate platforms are affected by relative changes in sea level.

The polygonal faults, especially the linear ones in the study area, could have created the original topography for the genesis of gullies.One of the main controls on carbonate platform geometry and facies distribution is the tectonic setting, which influences the subsidence rate, accommodation space, uplift, and basin configuration.After the end-Cretaceous mass extinction, carbonate platforms continued to form on the shores of Tethys. During the Palaeogene, the Earth went through a marked phase of global warming. Between about 60–55 Ma, three stages of carbonate platform development can be identified Tethys-wide (Scheibner and Speijer, 2007). During the first stage ...Carbonate is an AI-driven automated end-to-end testing tool that seamlessly integrates into your testing framework.
