英文摘要：

Salawusu site from Inner Mongolia represents a typical profile of the Upper Pleistocene in North China. It is also one of the sites yielding the first evidence of the presence of Homo sapiens in Pleistocene Asia. The present paper reviews the results of chronometric studies of Salawusu Formation from which the ＂Ordos wan＂ and Salawusu culture have been found. Qiu Zhonglang （1955） compared the Fluorine content between Salawusu PA.62 femur bone and other mammalian fossils from Salawusu Formation and indicated that the age＂ of PA. 62 is much younger than the other mammalian remains. Yuan Sixun （1983） et al collected some fossilized mammalian teeth and antlers from various stratigraphical position of primary Salawusu sediment and dated with Uranium series method. The result is that the lower Salawusu Formation was accumulated between 30 000- 50000 BP. Li Xingguo et al（1984） suggested that the date of ＂Ordos Man＂ and Salawusu culture should be 35 340 ± 1 900 BP according to the ^14C date of the carbon particles collected from Salawusu Formation of Fanjiagouwan. Dong et al （1998） compared the fluvio-lacustrine - aeolian sand sequence from the Dishaogouwan section with loess, deep-sea core records and climatic fluctuations of glacial period according to the stratigraphic subdivision and dating of the Dishaogouwan section. According to their opinions the fluviolacustrine facies of Salawusu Formation was formed in the last interglacial period from 140 000 to 70 000 BP, roughly corresponding to the fifth stage of deep-sea oxygen isotope record, and developed in the same period as the palaeosol S, on the Loess Plateau. Yin Gongming et al （2004） collected three samples for IRSL dating from the Paleolithic Culture layer of Fanjiagouwan locality, Salawusu site. The IRSL ages indicate that this is older than 61 000 ± 4 900 BP and younger than 68 000 ± 7 300 BP. Fan et al （2002） have collected 140 samples from the profile of Dishaogouwan for paleomagnetic dating. The distance between two
