The Florida peninsula is located on the eastern side of the platform, where in places it lies only 3 to 4 miles (4.8 to 6.4 km) from the platform's edge. On the gulf side the platform ends over 100 miles (160 km) to the west of the modern shoreline, where a massive cliff rises over 6,000 feet (1,800 m) from the 10,600 feet (3,200 m) depth of ...
The emergent portion of the platform was created during the Eocene to Oligocene as the Gulf Trough filled with silts, clays, and sands. Flora and fauna began appearing during the Miocene. No land animals were present in Florida prior to the Miocene. The largest deposits of rock phosphate in the United States are found in Florida. [1]
Depiction of the Gulf Trough over Florida. The Gulf Trough , also known as the Suwanee Straits , [ 1 ] is an ancient geologic feature of Florida present during the Paleogene period. A strong marine current , similar to the Gulf Stream , scoured the trough from southwest to northeast.
The Florida peninsula is a porous plateau of karst limestone sitting atop bedrock known as the Florida Platform. The emergent portion of the platform was created during the Eocene to Oligocene as the Gulf Trough filled with silts, clays, and sands. Flora and fauna began appearing during the Miocene. No land animals were present in Florida prior ...

The Atlantic Coastal Ridge is a geomorphological feature paralleling the Atlantic coast of Florida from the border with Georgia to Miami-Dade County, where it transitions into the Miami Rock Ridge. For most of its length it consists of one or more relict beach ridges created when the sea level was about 30 feet (9.1 m) higher than at present.
All of the Florida Platform would have been above sea level, with the west coast of the Florida peninsula being about 150 miles (240 km) west of the current coast. Sea levels were rising when the first people reached Florida late in the Pleistocene epoch. Sea level at the end of the Pleistocene epoch was about 40 metres (130 ft) lower than at ...
The Peninsular Arch parallels the Ocala Platform to its west and is the dominant sub-surface feature within Florida. It is a structurally high area which affected deposition of sediments during the Cretaceous to the early Cenozoic.
