From a certain depth, most of the carbonates dissolve, but the shells of the most resistant foraminifera do not. It is the LISOCLINE
.
From a certain depth, carbonates and microfossils dissolve completely beyond lysocylin. It is the CALCITE COMPENSATION LEVEL (CCD)
.
In areas deeper than the CCD, only clay or siliceous sediments are deposited and carbonates and carbonated fossils are absent
.
Lysocline and CCD vary in depth today in each ocean, being greater in the tropical belt (up to 5000 m)
. The CCD for the same latitude has varied throughout geological time
.
