Ocean Sediments-Lecture Notes ... Below this level, the ocean water is too cold and the pressure too high for calcium carbonate to be stable. Therefore, the biogenous sediments are primarily siliceous. Main sources of biogenous sediment are: DIATOMS, RADIOLARIANS, ... These sediments are very rare on the ocean floor.

Billions of tonnes of sediment accumulate in the ocean basins every year. The nature of such sediments may be indicative of climate conditions near the ocean surface or on the adjacent continents. Sediments are composed of both organic and inorganic materials.
