Speleothems, or carbonates formed in caves, are becoming increasingly important as paleoenvironmental archives, primarily because they can be precisely and accurately dated from ~500 ka to present using U-series techniques. Though establishing robust transfer functions for various geochemical proxies in speleothems has proven to be a daunting task, several recent studies have shown that speleothems faithfully record orbital and shorter-scale climate variability, primarily reflected by their stable O and C isotopic compositions, as well as by changes in lamina thickness and trace elements. For this session, jointly organized by the Stratigraphy, Sedimentology and Paleontology and Climate: Past, Present and Future Divisions, we welcome papers that address all aspects of speleothem chronology, including their significance as recorders of past environmental changes. We are particularly interested in studies that critically evaluate the robustness of U-series based age models of stalagmite and flowstone samples, improve our physio-chemical understanding of commonly used transfer functions, and assess their paleoclimatological significances by comparison with other terrestrial archives.
The session will be of interest to paleoclimatologists, Quaternary geologists, sedimentologists, hydrogeologists and speleologists wishing to acquire state of the art data and interpretations on this fast growing field of terrestrial climate history research.
