The structure of the Florida platform, the foundation of which came from the African Plate over 200 million years ago.. The Floridian peninsula is a porous plateau of karst limestone sitting atop bedrock known as the Florida Platform.
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 underlying bedrock or limestone of the Everglades basin affects the hydroperiod, or how long an area within the region stays flooded throughout the year. [37] Longer hydroperiods are possible in areas that were submerged beneath seawater for longer periods of time, while the geology of Florida was forming.
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 ...
Miami Limestone (formerly Miami Oolite, orange on map) in relation to other formations in South Florida. The Miami Limestone, originally called Miami Oolite, is a geologic formation of limestone in southeastern Florida. Miami Limestone forms the Atlantic Coastal Ridge in southeastern Florida, near the coast in Palm Beach, Broward and Miami Dade ...
Karst topography is a geological formation shaped by the dissolution of a layer or layers of soluble bedrock, usually carbonate rock such as limestone or dolomite, but also in gypsum. [1] It has also been documented for weathering -resistant rocks, such as quartzite , given the right conditions. [ 2 ]
Two sites within the Ocala Limestone yielded Upper Eocene Valvatida (sea stars) and mollusks. University of Florida and Florida Museum of Natural History paleontologists numbered the Haile fossil sites with Arabic and Roman numbers and letters in order to define locations more distinctly. UF scientists used Roman numbering and the FLMNH ...
Formerly a geologic group, Ocala Limestone was downgraded to formation status by T.M. Scott in 1991. [1] The Ocala Limestone consists of almost pure limestones with occasional dolomites . It can be subdivided into both lower and upper facies with the lower facies composed of a whitish to cream-colored, fine to medium grained, poorly to ...
