Miami Limestone forms the Atlantic Coastal Ridge in southeastern Florida, near the coast in Palm Beach, Broward and Miami Dade counties. It also lies under the eastern (Miami-Dade County) part of the Everglades, Florida Bay, and the lower Florida Keys from Big Pine Key to the Marquesas Keys. [1] Mitchell-Tapping also states that a component of ...
The limestone that eroded from the reef formed oolites in the shallow sea behind the reef, and together with the skeletal remains of bryozoans, formed the Miami Limestone that is the current surface bedrock of the lower Florida peninsula and the lower keys from Big Pine Key to Key West.
The pine rocklands in Miami-Dade County and Everglades National Park are found on limestone substrates along the Miami Rock Ridge, an exposed oolitic limestone matrix 2–7 meters above sea level that extends from northern Miami to the southern Everglades with disjunct sections in the Lower Keys. [4] This limestone is extremely sharp, porous ...
The Key Largo Limestone are reefs up to 200 ft (61 m) thick, parallel to the shelf edge, consisting of hermatypic corals and calcarenites. The Miami Limestone is less than 49 ft (15 m) thick, and in general is found behind the Key Largo Limestone reef, but overlies it in the western extent of the keys.
The Key Largo Limestone is a fossilized coral reef formed during the Sangamonian Stage of about 75,000 to 125,000 years ago. The Miami Formation achieved its present form somewhat later, during a glacial period in which fresh water consolidated and cemented the lagoon deposits. [8] The Key Largo Limestone is a coarse stone formed from stony ...
The globally imperiled pine rockland community, which also encompassed the Florida Keys and The Bahamas, supported numerous endemic plant species; 20 percent occur nowhere else in the world. [7] The communities of the Miami Rock Ridge are maintained by wildfires, including natural fires caused by lightning strikes; this affects the vegetation ...
