摘要In the past decades, archaeologists have found evidences for prehistorical human activity in the Qinghai-Tibetan Plateau (QTP). In 1982, some Paleolithic stone tools were found in a section from a terrace of the Xiao Qaidam Lake in the Qaidam Basin, NE of the QTP. The age of this Paleolithic site has remained unknown by far. Some believed that the age of human inhabitation in this Paleolithic site was about 30 ka. In this study, quartz optically stimulated luminescence was used to date 10 samples collected from four sections in the Xiao Qaidam Lake, using the single-aliquot regeneration-dose protocol. The two samples from section XCDH2, which is from a lake terrace about similar to 7-8 m above the present lake level and in which the top gravel layer contains stone tools, were not well-bleached before deposition. Their ages (>101 and >159 ka) determined by SAR should be considered minimums. OSL dating results of six samples from two sections (XCDH1 and XCDH3) of an adjacent lake terrace, which is similar to 12 m above the present lake level, suggest two possibilities for the age of the tool-bearing gravel layer: (1) younger than similar to 3 ka if the lake terrace of XCDH2 is younger than the terrace represented by XCDH1 and XCDH3; or (2) between similar to 3 and 11 ka if these two terraces are part of the deposit of the same time period. In either case, the age of the archaeological layer should be much younger than the previously proposed similar to 30 ka. As the climate in the early Holocene after 11 ka was increasingly warm and the Xiao Qaidam Like area could be suitable for human inhabitation then, we deduce that the age range of similar to 3-11 ka is more likely the time frame for this archaeological site. The age of 3.1 +/- 0.3 ka for the surface of terrace XCDH1/XCDH3 suggests a significant lake level decrease after this time and a corresponding arid event at similar to 3 ka; the lake level did not reach this level again after that time. Section XCDH4 is more than 40 m above the present lake level, and two samples gave ages of 37 +/- 4 and 51 +/- 4 ka. These two dates and the dates from the other sections demonstrate that two lake levels higher than present existed for Xiao Qaidam Lake, one at similar to 12 m and dated similar to 3-11 ka and the another at >40 m and dated similar to 37-51 ka.
