Limestone is a type of carbonate sedimentary rock. It is composed mostly of the minerals calcite It is most common in the tropics, and it is known throughout the fossil record (see Taylor and Wilson, 2003). The world's largest limestone quarry is at Michigan Limestone and Chemical Company in Rogers City, Michigan.
