Limestone can also be chemical in origin as is the case with travertine. Chemical limestone forms when calcium and carbonate ions suspended in water chemically bond and precipitate from their aquatic sources. Because of its high calcium content, limestone is usually light in color, although many variations exist.
Limestone quarries, the dark rectangular shapes just west of the urban areas, provide about half of the rock used in Florida's construction.
