That's why it is the dominant component of the lithogenous sediments including sand. The ancient remains of which of the following, buried before they could decompose, are the source of today's petroleum deposits? There are four kinds of marine sediments, Lithogenous, biogenous, hydrogenous and cosmogenous. Sediment accumulation will depend on the the amount of material coming from the source, the distance from the source, the amount of time that sediment has had to accumulate, how well the sediments are preserved, and the amounts of other types of sediments that are also being added to the system. Coarse lithogenous sediments are less common in the central ocean, as these areas are too far from the sources for these sediments to accumulate.
