Dating of Marine Sediments for Archaeological Purposes



Introduction to dating glacial sediments

Please note that Internet Explorer version 8. Please refer to this blog post for more information. Establishing accurate chronologies for Late Quaternary Antarctic marine sediments is often a challenge due to variable radiocarbon reservoir effects, the presence of coarse-grained glacial material and a lack of carbonate preservation. Without accurate age control the scope for precise comparison of palaeoenvironmental records is severely limited. Dating marine sediments order to address this, we combined diatom abundance stratigraphy, magnetic and radiocarbon methods to build an accurate chronology for two late glacial marine sedimentary sequences, from cores TPC and TPC from the Scotia Sea, SW Atlantic.

Together, these key findings provide an accurate age model between dating marine sediments The age model was further extended to Radiocarbon dating did not provide dates that were in stratigraphic order, and magnetic susceptibility only identified glacial interglacial transitions in one core. We demonstrate that combining geomagnetic and diatom abundance data can enable generation of high-resolution geochronologies for glacial sediments from the Scotia Sea, and offers the potential for more widespread comparison and correlation of Antarctic and Southern Ocean palaeoenvironmental dating marine sediments.
