Typical values for the CCD are between 3000 and 4000 m, but since the CCD also depends on the amount of calcite in the water it can occur as shallow as 2500 m (in parts of the Pacific Ocean). These shallow zones are often caused by high biological activity of carbonate shell forming organisms.

Taking all this together it becomes clear carbonate deposits can form and/or be preserved only above the CCD.
