【摘要】 山西北部桑干河中游的尉家小堡遗址,是华北地区以细石器加工技术为特征的旧石器时代晚期遗址,石制品岩性以硅质岩和火山角砾岩为主。细石核全部为楔形石核,显示出一套较为成熟而稳定的制坯及剥片工艺,包括软锤修整楔状缘、压制产生细石叶等。石器类型全部为刮削器。5.6%的拼合率说明此处为原地埋藏遗址。通过与同时代桑干河流域的其他遗址石制品的比较和遗址出土较精致的穿孔骨制品的现象判断,此遗址的年代应在旧石器时代晚期之末。更多还原

【Abstract】 Yujiaxiaobu site was discovered in July,1996,which located at 1500m to the south of Shenquanbu village and 1000m to the northwest of Yujiaxiaobu village,Yanggao County,Shanxi Province.A total of 572 pieces typical microlithic stone artifacts were found from a 2m~2 area in the bottom of the Late Pleistocene loess.The stone artifacts include cores,flakes,micro-cores,micro-blades,implements and debris.The implements are all scrapers.Raw materials are mainly silicalite and volcanic.A special technology of wedge-shaped microcore is known from here.The study of systemic refitting and comparing shows that it’s an undisturbed site.Comparing the stone artifacts and cultural character with other Late Pleistocene sites in Nihewan Basin,Yujiaxiaobu site can be attributed to the Upper Paleolithic.更多还原
