Deep-Sea Sedimentation

Abstract: In a volume on the geology of continental margins, a section on deep-sea sediments would seem in need of explanation. First, deep-sea sedimentation includes both the eupelagic and the hemipelagic facies domain, the latter being greatly influenced by continental margin effects. Second, all oceanic sedimentation is part of a global geochemical system, so processes in one realm have profound effects on sedimentation in the other. Third, the plate tectonics paradigm provides for long-term interaction between continental and oceanic crust at the continental margins. Thus a record can be preserved, however jumbled, of the workings of the biogeochemical fractionation apparatus that is the world ocean—be it obscure, as in the rocks and ore bodies of Andean mountains, or in ophiolite suites and ancient pelagic sediments of the Alpine chains.
