摘要

THE Yellow River, with its huge amount of silt charge from the Loess Plateau, is the second largest river in China, Its lower reach has become a famous hanging river because of serious silting up, and the magnitude of discharge changes much from season to season. As a result of silting, migration of the stream channel happens frequently, Lateral erosion of channel or point bars, and scarp slopes forming during the erosion may be often observed. The silt stalactite, hitherto not reported, usually forms on surfaces of the slope. As a newly found kind of sedimentary structure, the silt stalactite may have some significance to the study of sedimentary environments and paleoclimate.
