Describes the palaeoclimatic changes reflected by karstic cave deposits during the Quaternary Period in China. The study was based on comprehensive analyses of the spore and pollen, palaeontological, and palaeoanthropological fossils as well as various kinds of sedimentological features preserved in those cave deposits. The caves studied include those containing fossils of <i>Homo erectus</i> and <i>Homo sapiens</i> in the Zhoukoudian area some 50 km southwest of Beijing and Shenxiandong (the Immortal Cave) in Leishui County, Jiangsu Province, about 120 km southeast of Nanjing. These deposits, which range in thickness from two to 40 meters, have been carefully investigated and have shown to be representative of portions of the Quaternary. The palaeoclimatic fluctuations as recorded in these cave deposits have been well correlated with glacial cycles within the Brunhes Normal Epoch based on the oxygen isotope scale determined from deep ocean cores.
