lysocline
Noun
Meaning
lysocline (plural lysoclines)
The depth in the ocean below which solubility of calcium carbonate (CaCO3) increases dramatically.
Examples
Calcareous sediment that sinks below the lysocline dissolves, as a result no limestone can be formed below this depth.
Below about 3,000 meters, water pressure and temperature conditions cause the dissolution of calcite to increase nonlinearly, so limestone typically does not form in deeper waters (see lysocline ).
