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]
During the Paleogene, what would become Florida was the submerged Florida Platform, a feature not unlike the Bahama Banks composed of carbonate sediments containing foraminifera, corals, bryozoa, and mollusks. Due to the current running through the Gulf Trough, materials needed for sedimentation were instead carried away toward the 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.
During the Aquitanian faunal stage (early in the Miocene), extensive upwelling around the Florida Platform carried plankton into the Okeechobean Sea and Tampa Subsea, depositing phosphorus-rich carbonate layers in the basins. The deposits in the Okeechobean Sea became the Nocatee Member of the Arcadia Formation, and the deposits in the Tampa ...
The history of Florida can be traced to when the first Paleo-Indians began to inhabit the peninsula as early as 14,000 years ago. [1] They left behind artifacts and archeological evidence. Florida's written history begins with the arrival of Europeans; the Spanish explorer Juan Ponce de León in 1513 made the first textual records.
The Fort Thompson Formation is a geologic formation in Florida. It preserves fossils dating back to the late Pleistocene . It was influenced by sea level changes.
