Limestones. The most common chemical sedimentary rock is limestone. Composed mostly of the mineral calcite (CaCO 3), limestones are usually formed by biochemical processes in shallow seawater. Coral and algae are especially important limestone builders. Oolitic limestones form in ocean shallows from the accumulation of oolites, sand‐sized spheres of chemically precipitated calcite that
