This chapter is intended as a concentration of base data on stratigraphy, petrography, and fossil content of drift (post-rift) sediments in the Atlantic region. Some regional generalizations about the role of tectonic and other geological processes are drawn; broader generalizations are summarized in the chapter on Evolution of the Ocean Floor. Before details are discussed, a general description of the drift supersequence is needed. This includes differences from sediments of the earlier synrift supersequence, separation of the two super sequences by a broad unconformity, and the control over drift sedimentation exerted by continental-margin subsidence, sea-level changes, and climate changes.
