Sediments on the ocean floor only rarely come from a a single source.
Main source of sediment on ocean floor.
New global analysis reveals amount of sediment on the ocean floor.
Deep ocean sediment containing at least 30 biogenies material is called.
Pelagic sediment or pelagite is a fine grained sediment that accumulates as the result of the settling of particles to the floor of the open ocean far from land.
The main source of terrigenous sediments.
These particles consist primarily of either the microscopic calcareous or siliceous shells of phytoplankton or zooplankton.
It is further contoured by strong currents along the continental rise.
Silicious silica rich and calcareous calcium containing.
This graphic shows several ocean floor features on a scale from 0 35 000 feet below sea level.
Or some mixture of these trace amounts of meteoric dust and variable.
The following features are shown at example depths to scale though each feature has a considerable range at which it may occur.
Most deposits are a mixture of and particles.

Some may call this sediment biogenous sediment and this sediment roughly covered 75 of deep seafloor and one of the most important constituents of ocean sediments.
Some of these organic.
Terrigenous sediment is derived from land and usually deposited on the continental shelf continental rise and abyssal plain.
Continental shelf 300 feet continental slope 300 10 000 feet abyssal plain 10 000 feet abyssal hill 3 000 feet up from the abyssal plain seamount 6 000 feet.
This sediment is composed of clay particles and microskeletons of oceanic organisms that sink slowly through the water column to the ocean floor.
The ocean basin floor is everywhere covered by sediments of different types and origins.
Sediment thickness in the oceans averages about 450 metres 1 500 feet.
The only exception are the crests of the spreading centres where new ocean floor has not existed long enough to accumulate a sediment cover.
