ABSTRACT
The distribution of the various Recent pelagic deposits is roughly correlated with depth. Thus over much of the Atlantic and Pacific oceans Red clays occur in the deepest parts, Radiolarian oozes form in shallower waters deeper than about 4500 m, calcific foraminiferal oozes lie on the ocean bed between 4500 m and 3500 m, above which point aragonitic pteropod and foraminiferal oozes are found (Figure 13.1).
