Current and sea level control the demise of shallow carbonate
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 the path of the South Equatorial Current. Its reefs do not reach sea level, and all carbonate production is mesophotic to oligophotic.

Carbonate ramp depositional systems
Abstract. The classification, tectonic settings, stratigraphy and early diagenesis of carbonate ramp systems are reviewed. Carbonate ramps are common in all geological periods, but were dominant at times when reef-constructing organisms were absent or inhibited. Ramps can be subdivided into inner-, mid-, and outer -ramp environments.

This work highlights the difficulties in sequence stratigraphic interpretations in cases of neritic carbonate factory collapse without assessments of shoreline movement because the stacking patterns in open marine environments do not necessary reflect the regional variation in base level in disturbed carbonate systems.

Methane-derived authigenic carbonates
Carbon is primarily buried in marine sediments as carbonate and organic carbon, which removes carbon from the water column and the biological carbon cycle to the vast but slower geological carbon cycle within sediments (Falkowski et al., 2000).Marine sediments also host the largest reservoir of methane (CH 4), a potent greenhouse gas …

Carbonates-Reefs
Carbonates are made by living organisms in which calcium carbonate makes up the organism's shell and skeleton. Calcite and aragonite are polymorphs that are the two main types of calcium carbonate made by organisms. The reaction is Ca 2+ + Co3 2- to CaCo3 which can either go in the forward or backwards direction.

Carbonate systems
In carbonate systems, as thermodynamic open systems, there is a transfer of energy and matter through system boundaries. Energy transfers into the system both as light (radiant energy) and as hydrodynamic energy. Light is fundamental for the primary production and, in the ocean, depends on the light penetration coefficient, which is a …
