Abstract: Shuiyang River paleolithic site group is on the lower reaches of Yangtze River in AnhuiProvince. It consists of 16. localities, and covers 1400 square kilometers area.
Investigation and trial excavation at Xiang yang locality (AX 8704) show that most localities of paleolithic site group are at the second terrace. Bottom of the terraceis gravel bedabout 10-meter high, and deposits on it are loesslike silty clay 11-meter high. Section is quite si-milar with loess in North China. There are 7 paleosoil layers in deposits. According to theanalysis of grainsize, chemical, heavy mineral and electron microscope scanning, primary se-diments were carried by wind besides the gravel bed.
The age of ESR dating method of the middle and upper layer of Xiangyang locality is0.68ma BP. Summing up the results of TL and PM dates in small area in recent years, t.hesediment age of paleolithic site group of Shuiyang River has kept about 0.7ma (0.13--0.9ma).
The basic characteristics of paleolith in Shuiyang River are as follows: localities distribu-ted along the river; stone artifacts in original deposits, which put together relatively with peb-ble in the strata; their material made from flood land; figure is heavy and strong;most typesis chopper/chopping tools. These characteristics demonstrate the people who lived near the bankof Shuiyang River spent mobil life in groups then. Maybe paleolithic site group in ShuiyangRiver is the living complex of a primitive horde.
