摘要: [1] The loess-paleosol sequences in north China act as a key archive the study of continental paleoclimatic change over last 2.6 Ma. However, correlation between loess records and marine sediments 2.6–1.2 Ma BP interval is poorly studied. In this paper, Zr Rb concentrations were measured on samples taken at 20 cm intervals from Lingtai section BP. Because enriched coarse grain fractions whereas fine which are retained during pedogenesis, Zr/Rb can reflect original size variation serve proxy for winter monsoon strength. Our ratios generally match δ18O record, especially 1.9–1.2 interval. Strong 400 ka periodicity cycles found ratio record similar to δ13C suggesting possible low latitude influence regime
