Limestone formation.

Karst is an area of land made up of limestone. Limestone, also known as chalk or calcium carbonate, is a soft rock that dissolves in water. As rainwater seeps into the rock, it slowly erodes. Karst landscapes can be worn away from the top or . dissolved from a weak point inside the rock.. Karst landscapes feature caves, underground streams and …lagoon which allowed for the formation of salts and other evaporite minerals (like anhydrite and gypsum) from Paleocene to middle Eocene times. Carbonates continued to accumulate across the Florida Platform, and two major rock units—or formations—that were deposited during this time are the Avon Park Formation and the Ocala Limestone.
