Summary: More than 1000 samples of sediments from DSDP legs in the western and eastern North Atlantic were analysed semiquantitatively by XRD; approx 35 different minerals are shown in diagrams. The Oxfordian to Quaternary section from the western North Atlantic consists of argillaceous limestones, limestones, claystones and shales, zeolitic claystones, nanno-marls, siliceous oozes/clays/cherts, and hemipelagic muds. For the eastern North Atlantic section, no sedimentary formations could be paralleled to those of the western North Atlantic. Seismically mappable reflectors are in most cases related to changes in lithology and mineral composition.
