Geologic Map of Florida

U.S. Geological Survey

Florida has had a long and placid history, most of it under warm waters where limestone deposits built up over millions of years. This map was made in 1964 by the U.S. Geological Survey and the Florida Board of Conservation at a scale of 1:1,000,000. Almost every geologic unit on it is very fine grained shale, mudstone, and limestone, but there are some sandy layers, especially in the north, and a couple of phosphate layers that are extensively mined by the chemical and fertilizer industries. No surface rock in Florida is older than Eocene, about 40 million years old.
