2012-8-31 · Limestone is a chemical sedimentary rock that is created from the remains of calcium bearing organisms and chemical precipitants. The calcium can come from the shells and/or the skeletal fragments of deceased organisms. Over millions of years, the calcium normally contained within the shells of marine and land organisms is broken down and put into solution. Calcium rich solutions are
