WebSiliceous oozes predominate in two places in the oceans: around Antarctica and a few degrees of latitude north and south of the Equator. At high latitudes the oozes include mostly the shells of diatoms.

If the exposed sea bed is below the CCD tiny shells of CaCO 3 will dissolve before reaching this level, preventing deposition of carbonate sediment.
