Preliminary Calibration of Stalagmite Oxygen Isotopes from Eastern Monsoon China with Northern Hemisphere Temperatures

Changes in stalagmite oxygen isotope ratios that are related to the India Monsoon during the Holocene have been widely discussed (e.g., Neff et al., 2001, Fleitmann et al., 2003). The number of stalagmite oxygen isotope series from the Holocene in China that have been reported is limited but increasing (Hou et al., 2003, Zhang et al., 2003, 2004, Wang et al., 2005). However, the relationships between the oxygen isotope ratios of stalagmites from northeastern and southeastern China have not been discussed. In this preliminary report, we compare the stalagmite oxygen isotope records from the Eastern Monsoon China (East of 108°E), and focus on two questions:
