Florida has unique origins. What would become the basement rocks of Florida were once part of other continents. During the early part of the Cenozoic Era, Florida was submerged under a warm, shallow, ocean which explains why our entire state has hundreds to thousands of feet of limestone beneath it! Land emerged from the ocean as sea level fell during the Oligocene Epoch.

Limestone. Limestone is a chemical sedimentary rock that is at least 50 percent calcium carbonate in the form of the mineral calcite. Limestone may also contain small particles of other materials, such as quartz, feldspar, clay minerals, pyrite and siderite, and it may contain larger nodules of chert, pyrite or siderite.

Fossils are common in limestone. Limestone fizzes in dilute hydrochloric (HCl) acid, because it is composed of the mineral calcite, CaC03. Some limestone contains chert, which is very, very hard silica (like flint). It typically weathers to brown on the surface and occurs in nodules and occasionally replaces fossil …
