LATE PLEISTOCENE FLUVO-LACUSTRINE DEPOSITS AND AEOLIAN LOESS IN NORTH CHINA
Zheng Honghan(Institute of Geochemistry, Academia
The Late Pleistocene deposits of North China are best developed in the middle reaches of the Yellow River. Two sedimentary units are distinguished, which consist of aeolian loess and fluvo-lacustrine sands and gravels, respectively. Chronology, polynology, and analysis of sedimentary facies show that the Late Pleistocene fluvo-lacustrine deposits can be subdivided into different stages. The stratigraphic level containing Salawusu fauna may be compared with stage 6 with respect to δ18O and the deposits developed in other locations with Weichse-lian glaciation. The bottom boundary of Malan loess or the development of the first paleosol is chronologically different from place to place. The Late Pleistocene aeolian loess and flu-vo-lacustrine strata are synchronous deposits with different sedimentary facies and deposited in different morphologic units.
