Plants and animals absorb calcium carbonate from water – where it exists, in most cases, in the dissolved form of calcium hydrogen carbonate Ca (HCO3)2 – and use it to build up their skeletons and shells. After their death, crustacea, coccoliths, algae and corals form sedimentary deposits on sea-beds, thus the rock forming process is put in motion.

As limestone, calcium carbonate is a biogenic shake and is more compacted than chalk. As marble, calcium carbonate is a coarse-crystalline, changeable shake, which is framed when chalk or limestone is re-solidified under states of high temperature and weight. The properties of calcite make it a standout amongst the most broadly utilized minerals.
