Summary: Very fine quartz sand was examined from Paleogene and Neogene sediments of ODP Sites 693-697 to determine their grain roundness and surface texture characteristics unique to East (Site 693) and West (Sites 695, 696, and 697) Antarctica and to glacial regimes. Once identified, these distinguishing features could then be used to determine changes in source area and glacial conditions in the central Weddell Sea Basin (Site 694). Three end members of very fine quartz sand are recognized in the Oligocene to Pleistocene sediments of the Weddell Sea: angular, rounded, and intermediate. These sands are presumed to be derived from the Beacon-type rocks in East Antarctica and the sedimentary deposits of the northern Antarctic Peninsula, and from felsic intrusives, east antarctic quartzites, basement metamorphics of the South Orkney Microcontinent, and/or the Andean intrusive series of West Antarctica. No features unique to either the east or west antarctic sediment sources or to glacial conditions could be isolated. Therefore, the objective of determining provenance changes and sediment erosion and transport mechanisms could not be achieved using this approach. (Auth. mod.)
