An interesting article.
The internal stratigraphy of deep sea sediments was being discussed in "Questions about marine sediments" at http://
EvC Forum: Questions about marine sediments -->
EvC Forum: Questions about marine sediments . One of the things that I found were some really nice color figures that shows how plate tectonics influences the types of sediments accumulating within the Pacific and Atlantic Ocean on pages 32 and 33 of "Marine Sediments". This article can be can be downloaded from:
http://www.ldeo.columbia.edu/~rroberts/Lect-3.pdf
In addition, another study guide illustrated how plate tectonics influenced the types of sediments accumulating within oceans in "13. Overview: Marine Sedimentation" at:
http://bell.mma.edu/.../UWMarineGeology/McDuffSediments.html
This web page contains some interesting figures, which show how plate tectonics influences the accumulation of different sediments. The figure that illustrates this process can found at:
http://bell.mma.edu/~jbouch/UWMarineGeology/fs30-4.gif
This is figure 13-5 from:
W.S. Broecker and T.-H. Peng (1982) Tracers
in the Sea, Eldigo Press, 690 pp.
In the pdf file and the figure cited above, is showed there is a predictable stratigraphy of deep sea sediments that can found across both the Atlantic and Pacific Oceans. The curious thing is this stratigraphy is consistent with the sediments covering the oceanic crust as having accumulated during the slow movement of continental plates. However, it seems that it would be virtually impossible for the same stratigraphy of deep sea sediments illustrated in the figures shown in the pdf file and web page to have been created during a period of accelerated plate tectonics when the dynamics of the modern oceans were completely different than today.
