Key Largo Limestone in relation to other surface formations in South Florida. The Key Largo Limestone is a geologic formation in Florida.It is a fossilized coral reef. The formation is exposed along the upper and middle Florida Keys from Soldier Key (at the north end of the Florida Keys) to the Bahia Honda Channel (at the west end of Bahia Honda Key).
Keystone is a type of limestone, or coral rag, quarried in the Florida Keys, in particular from Windley Key fossil quarry, which is now a State Park of Florida. The limestone is Pleistocene in age, and the rock primarily consists of scleractinian coral, such as Elkhorn coral and Brain coral. Example of fossil Brain coral (Diploria) at the ...
Florida is tied with North Dakota as having the fewest earthquakes of any US state. [7] Because Florida is not located near any tectonic plate boundaries, earthquakes are very rare, but not totally unknown. In January 1879, a shock occurred near St. Augustine. There were reports of heavy shaking that knocked plaster from walls and articles from ...
The Florida Keys, islands off the south coast of Florida, are composed mainly of oolitic limestone (the Lower Keys) and the carbonate skeletons of coral reefs (the Upper Keys), which thrived in the area during interglacial periods when sea level was higher than at present. [97]
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 Dry Tortugas are the western extension of an arcuate chain of Pleistocene reef and oolitic limestone islands, with the eastern limit in the vicinity of Miami. These Florida Keys are the surface expression of the 3.7 mi (6.0 km) thick southern Florida carbonate platform, which has been accumulating sediments since the Early Cretaceous.
You can thank the wind for the odor.
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]
