Abstract: Two microlithic archeological sites, Zhaowangcun and Mengjiazhuang were discovered in the second terrace of the bank of the Quanshuihe River northeast of Yushe County, Shanxi Province. We gathered many stone artifacts and two ornament abjects made of bone and shell, and some fossil bone fragments in the sites. A radiocarbon date of 10290±110 years ago on collagen from a butchered horse bone from the Zhaowangcun and a date of 11960±150 years ago on rhinoceros humerus collagen from the Mengjiazhuang are consistent with the geomorphological and stratigraphic data with respect to the general age of the deposits.
More than 200 stone artifacts were excavated or collected. These artefacts include typical micro一cores, microblades and small and fine implements, such as various scrapers, burin, arrowheads and others. Judging from the micro-cores which basically belong to the celt-shaped micro-core pattern, the technology of the micro-cores appears to be a continuation of the technology of the micro-cores from the Xiachuan site. But judging from the fine arrowheads which suggest that bow and arrow had been used and the ornament abjects which were meticulously bored and ground in the Zhaowangcun site, it is clear that the assemblage is more advanced than those from the Xiachuan site.
