Chronostratigraphic Advances in the Radiocarbon Era: Integrating Paleomagnetism, Tephra, Climate Correlation, and Other Stratigraphic Methods

Session ID#: 24583

Session Description:
Radiocarbon provides the foundation for sediment chronostratigraphy over the last 50 ka. However, availability of datable material, variability in reservoir ages, and other complications can preclude radiocarbon determination of the exact timing of paleoenvironmental changes. Other stratigraphic methods can be used to address these uncertainties. For example, paleomagnetic secular variation (PSV) allows for independent correlation of records on centennial to millennial scales through variations in inclination, declination, and relative paleointensity. Comparison of geomagnetic signals in different archives (e.g. marine, lacustrine, cosmogenic) can extend well-dated chronologies to organic-poor sediments and assess the evolution of marine reservoir ages. Additionally, recent advances in our understanding of remanent magnetization acquisition and field modeling allow for new insights into the scale and variability of geomagnetic structures and quantification of chronostratigraphic uncertainty. We encourage submissions that integrate PSV and/or other stratigraphic tools—including tephra, ice core correlations, varves, among others—with radiocarbon to address paleo problems.
