Marble vs Limestone: Key Differences and Similarities
Stone Center - Limestone. Limestone is a sedimentary rock composed largely of calcium carbonate, formed millions of years ago by the accumulation of shells and skeletons of marine animals on the ocean floor. Ocean-dwelling organisms like clams, muscles, and choral use calcium carbonate found in seawater to create their exoskeletons and bones.
