Nevertheless, classification of carbonate platforms is not just a semantic or academic issue. For example, it is clearly important for the accurate interpretation of seismic images ...The Apulia Carbonate Platform is one of the most extensive MesozoiceCenozoic shallow water domains of the Tethyan ocean (Morsilli et al., 2017 and references therein). Its deposits crop out in ...Precambrian carbonate platforms have been widely described on several continents and are commonly used for reconstructing of paleoenvironments in Central Africa (Delpomdor et al., 2013; Préat et al., 2018).In Central African Republic (CAR), one of the most intriguing carbonate deposits is the Ombella-M'poko Formation (O.-M. Fm), which was deposited in a tectonically structured graben subbasin ...

For OAE1a, this scenario also explains the retreat of carbonate platforms to low latitudes in the early Aptian, as sea-surface water typically has a higher carbonate saturation in warm, lower than in cooler, higher latitude waters. The gradual decrease of aragonite throughout the Cretaceous matches model simulations of seawater carbonate ...

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 ...

The newly collected seismic data and the existing drilling data provide a good opportunity to better understand the carbonate platform distribution characteristics and the hydrocarbon resource potential in the Xisha sea area of the South China Sea. Based on the seismic data and the reflection characteristics of the carbonate platform’s edge, three boundary indicators were established: abrupt ...The carbonate platforms from the Yadana area are thus a representative example of the interplay between global mechanisms and local paleoenvironmental parameters on carbonate platform initiation ...A carbonate platform is a sedimentary body which possesses topographic relief, and is composed of autochthonic calcareous deposits.

LBF carbonate platforms developed on the southern Tethyan margin between Morocco (Mo: Fig. 1 B) and the Oman-Yemen domains at paleolatitudes ranging from 20°N and the equator (Höntzsch et al., 2013; Martín-Martín et al., 2020c, Martín-Martín et al., 2021). No z-corals oldest than middle Lutetian have been reported in this realm.

Syndepositional tectonic movement resulted in adjustments in carbonate platform and slope profiles (Playton and Kerans, 2002).Tectonism and subsidence waned during the late Wolfcampian and into the Leonardian (Wahlman and Tasker, 2013; Ewing, 2019).Decreases in tectonic movement also coincided with decreasing amplitude of sea-level fluctuations and a broad climatic shift generating ...

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 ... Carbonate contourite drifts are poorly documented in the onshore record because of the difficulty of implementing diagnostic criteria for their recognition. 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.Carbonate platforms first appeared during the early Miocene on fault-bounded blocks that had developed from the Eocene to the Oligocene within the NE-striking Xisha Uplift continental fragment.

Carbonate platforms are mainly distributed in tropical and subtropical low-latitude ocean shallow water areas, and their growth and development are very sensitive to environmental changes, such as water depth, temperature, waves, salinity, dissolved oxygen, sediment and nutrients [1,2,3,4].Changes in any of these controlling factors may alter the sedimentary structures of carbonate rocks and ...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 ...

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 extensionalCarbonate 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). ...The Great Bahama Bank (GBB), an isolated carbonate platform that is dominated by nonskeletal sands and muds (15-17), has been at the center of the debate for over a century (8, 18-24). Broadly, there are three prevailing hypotheses for mud formation. First, carbonate mud could be formed by algae (7, 20, 25).We studied the Otavi Group (), a carbonate platform covering the southern promontory of the Congo Craton in northern Namibia (15,18, 19).In the late Neoproterozoic, the Congo Craton was a Bahama-type sea-level platform that was about the size of the conterminous United States.Highlights Carbonate platform paired δ 13 C carb and δ 13 C org record of the early Toarcian CIE.

Shift from biotic to chemical carbonate factory across the T-OAE. Platform …Upper Triassic carbonate platforms from the Panthalassa Ocean remain less-understood and less-studied than their Tethyan equivalents. This imbalance is largely due to the poorer preservation state of Panthalassan carbonate rock successions in terms of rock quality and depositional geometries, which prevents good appreciation of depositional systems. In this context, carbonate exposures from ...Carbonate systems are based on the soluble carbonates ability to react with CO 2 to form bicarbonate and are able to release CO 2 and also revert to a carbonate, when heated. The significantly lower energy required for regeneration is a big advantage of carbonates over amine-based systems [27].Carbonate solutions are a good fit for large-scale CO 2 capture processes.We present here a new biostratigraphic, sedimentological and high-resolution carbonate-isotope analysis of the Campo section to reassess the PETM record, locate precisely the P/E boundary, reconstruct the environmental and sea-level changes across the PETM, and investigate hydrological changes and carbonate-platform response to the PETM abrupt ...
