Carbonate platform
From Wikipedia, the free encyclopedia
A carbonate platform is a geologic structure composed of carbonate sediments that have accumulated and lithified over a long period of time. Their tops are typically in shallow water, though the total thickness of rock may be considerable; the carbonates of the Bahama Banks can be traced down to a depth of at least 8,000 meters.[1]
The Bahama Banks are the most well-known carbonate platforms; the Yucatán Peninsula is another. Even the Florida Peninsula is a carbonate plaform, albeit one no longer submerged.[2]

[edit] Depositional Environment
Carbonate platforms are today restricted to warm, shallow, tropical ocean waters, which are favorable for carbonate-secreting organisms.[3] They are also limited to regions where the influx of terrestrial sediment (e.g., mud and silt from rivers) is minimal; murky water limits the growth of plankton, as well as dilutes any sediments that are deposited.[4]
