The Late Jurassic extensional regime from the Neotethyan area favoured the development of a complex system of carbonate platforms (Missoni and Gawlick 2011).In this context, shallow-water carbonates were accumulating during Jurassic, on a large crustal block belonging to the Dacia Mega Unit (Schmid et al. 2008).The Getic Carbonate Platform represents an integrating part of this system ...start to accumulate. Deep layers of carbonate rock—predominantly limestones and dolostones composed of the mineral calcium carbonate—built up over the next 200 million years to create Florida’s flat-topped, “carbonate platform” structure. These rock layers, two to three miles thick in some places, are a result of the near-constantMuch less is known about groundwater flow paths and geochemical evolution in partially confined platforms, particularly those supporting surface water. In north-central Florida, sea level rise and a transition to a wetter climate during the Holocene formed rivers in unconfined portions of the Florida carbonate platform.Corpus of Carbonate Platforms with Lexical Annotations for Named Entity Recognition.

The Shanganning Carbonate Platform (SCP) of the North China Craton (NCC) was located in the Trade Winds belt during the Cambrian, which influenced its facies development. In recent years, numerous drillcores have been recovered from these units, but the depositional environments and facies architecture of this large (~2.0 × 10 5 km 2 ...112 Carbonate platforms. 214: 113 Modern carbonate depositional environments. 219: 114 Summary. 231: 115 Further reading. 233: Sequence stratigraphy of carbonate depositional systems. 234: 122 Sequence stratigraphy of rimmed carbonate platforms. 241: 123 Sequence stratigraphy of carbonate ramps. 245:Carbonate platforms are built mainly by corals living in shallow light-saturated tropical waters. The Saya de Malha Bank (Indian Ocean), one of the world's largest carbonate platforms, lies in ...Drowned carbonate platforms on passive margins present a paradox, because their great growth potential exceeds the typical rates of passive margin subsidence and any relative sea-level rise driven by long-term processes in the geologic record. In this study, manned submersible observations, sampling, and high-resolution acoustic data were used to investigate a drowned isolated carbonate ...

SEPM Core ...The Archean carbonate platform on top a major unconformity, exposing wide areas of mafic rocks of the greenstone belt, in combination with ongoing hydrothermal activity, provided sufficient amounts of micro- and macro-nutrients, perhaps with occasional P limitation, sustaining a microbial community which may be capable of fixing carbon and ...The model finely simulates the global distribution of Lower Aptian and Modern carbonate platforms.

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 ...The generalized carbonate platform model displays the relative position of major carbonate depositional environments. It is important to understand that ...Carbonate platforms usually keep pace with subsidence and sea level rise but "platform drowning" occurs when carbonate sedimentation slows or when siliciclastics replace carbonates. Identifying specific mechanism(s) behind platform drowning is critical for understanding global environmental changes such as Ocean Anoxic Events (OAEs). ...

A carbonate platform is a sedimentary body which possesses topographic relief, and is composed of autochthonic calcareous deposits. [1] 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. The group of satellite images above show several small eddies swirling out from shallow waters along the Little Bahama Bank's carbonate platform. Similar swirls in the world's oceans are sometimes colored by large concentrations of certain types of phytoplankton —microscopic plant-like organisms that in abundance can discolor water and be ...First, the carbonate factory concept does not provide any prediction of local biota or grain distribution within a carbonate platform as factories are considered as …

antiques at gresham lake Ramp geometry and seismic character Carbonate depositional systems exhibit widely variable slope shapes, ranging from near vertical escarpments several kilometres high to epeiric platforms with little relief, and show correspond- ingly variable responses to relative sea-level changes (Kenter and Schlager, 1989). zillow vero beach for renthistory haiti 19 production of carbonate platforms fluctuated through time. Yet, the reasons for these fluctuations 20 are not well understood and the underlying mechanisms remain largely unconstrained. Here we 21 document the long-term trend in Cretaceous carbonate platform preservation based on a new dataThe 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. A dolomitized Wenlock-Lower Devonian microbial-algal reef-bearing carbonate platform hosts epigenetic copper-cobalt-germanium (Cu-Co-Ge) sulfide mineralization at ... ku volleyball live During the Holocene, carbonate platform weathering and erosion related to climate and precipitation intensified. Fresh water flowed through the reef body from seepage zone to the undercurrent zone, the unstable aragonite and high-Mg calcite of the reef body are weathered and eroded (Wang et al., 2017).The isolated carbonate platform is recognized based on diagnostic criteria defined by (Burgess et al. 2013) such as a positive antecedent topography, marked stratal thickening, high angle flanks, stacking patterns, distinct reflection amplitude, and geometry, and onlaps of surrounding sediments.
