Abstract:
Ten cores collected from Drift 7 on the Pacific continental margin of the Antarctic Peninsula were studied within the SEDANO-II Project with the aim of improving the depositional model proposed for the area by Rebesco and others. Glacial and interglacial cycles are distinguished, and eight sedimentary facies have been recognised. Grain-size and compositional analyses allow the definition of different depositional processes on the continental margin: the northeast gentle side of Drift 7 comprises expanded turbiditic and contouritic sequences, whereas the distal area contains condensed deposits; turbidites appear finer grained on the upper reaches with respect to the lower reaches of deep-sea channels.
