The first, third, fifth, seventh, ninth and eleventh stages were warm-wet periods; whereas the second, fourth, sixth, eighth and tenth stages correspond to relatively cool-dry periods. The climate history in the past 780 ka recorded in the XH-1 Core can be correlated with the patterns of grain size changes of Luochuan loess, and also to those of marine oxygen isotope stages (MIS). The patterns of palaeoclimatic evolution in this area thus were influenced by both global and regional factors.pace prefix = o ns = "urn:schemas-microsoft-com:office:office" />p>p>
