Calcium carbonate is unusual in that its solubility increases with decreasing temperature. [18] Increasing pressure also increases the solubility of calcium carbonate. The carbonate compensation depth can range from 4,000 to 6,000 meters below sea level. Role in taphonomy. Calcium carbonate can preserve fossils through permineralization.
