Ocean floor sediments

I need some help figuring out how the sequence of sediment layers are formed in the ocean in relation to the movement of plate tectonics and plate boundaries. For example if I was to look at a core from a drill site and decide what the sediment type would be on top and the one below it etc. The sediment types that I am working with are terrigenous, biogenous, and hydrogenous.

Taking into account the following: (excerpted from the fist link below)

6. General distribution of deep ocean sediments
a. Age and thickness of sediment increases away from ridges. Also far from the ridges the ocean is closer to sources of terrigenous sediments.
b. Terrigenous sediments dominate on the continental margins and in the highest latitudes where ice cover restricts biological productivity.
c. Siliceous oozes dominate in highly productive waters near the Equator in the ...

Solution Summary

Deals with sequences of sediments/stratigraphy close to shore on sea floor.

PLease help me with at least 200 words references cited. Thank you in advance

What are the different types of seafloor sediments, and what are the factors that control the distribution of each major sea sediment type? Where does each major seafloor sediment type tend to accumulate in greatest quantity (i.e., discuss the distribution of these sediments)?
