Geochemistry of Limestone Limestone comprises approximately 10% of all sedimen-tary rocks exposed on the earth's surface and is primarily biological in origin. Typically, limestone forms from the lithification (the process of turning loose sediments into rock) of marine organisms like shells, corals, and algae on the ocean floor.
