BIOCHEMICAL SEDIMENTARY ROCKS. (In a chemical limestone, the calcium carbonate is in the form of calcite mineral crystals.) As marine plants and animals die in the ocean, scavengers, waves or currents may break them apart, resulting in biochemical sediment comprised mainly of broken fragments of the original skeletons and shells.
