Dating and Recognition of Major Glaciations Events - Evidence from Unglaciated Continental Margins

Dating the multiple glacial episodes on Antarctic interior basins and margins can be very difficult as erosional events can be profound, and useful fossils for dating are missing in most of the depositional sequences. However, some episodes can be recognized in certain basins located along the paths of the currents generated or intensified by major climatic changes, as observed in southern Brazilian continental margin.
