Muav Limestone (averages 515 million years old) – The Muav is made of gray thin-bedded limestone that was deposited further offshore as calcium carbonate precipitates (see 3c in figure 1). It is fossil poor yet trilobites and brachiopods have been found in it. Calcium carbonate is the major component of limestone. Limestone is one of the prominent rocks in Florida due to the ocean and sea life. Calcium carbonate will decompose when placed in a container to form calcium oxide and carbon dioxide.
