山西柿子滩旧石器遗址蚌饰品制作工艺研究

Study on Technological Process of the Shell Ornaments Discovered from the Shizitan Palaeolithic Site

本文是对柿子滩遗址蚌饰品制作工艺的研究。该遗址分布于山西省吉县清水河流域,是一处含有细石器遗存的旧石器时代晚期遗址,年代为25000BP—10000BP。蚌质的出土遗物17件,发现于不同地点的不同层位中,其中有穿孔的5件,有磨制痕迹的3件,分别发现于S9、S12A和S29三个地点。研究表明,蚌饰品穿孔有"钻孔"和"磨孔"两种形式,存在三种制作程序,早期到晚期的制作和穿孔技术表现出越来越进步的特点。

This paper reports a preliminary study on technological process of making shell ornaments that were discovered from Shizitan,a microblade-industry Palaeolithic site complex in southwestern Shanxi,dated to 25000-10000 BP.Five finished shell ornaments and 3 by-products were identified from cultural layers at different locations of the sites.Based on perforating techniques,these shell ornaments are classified into ＂drilled-perforation＂ type and ＂grounding-peroration＂ type.Subsequently three methods of manufacturing processes are identified.The perforations seem to be larger in earlier period than in later period,reflecting the plausible changes of drilling techniques and possible different function over time.Also changes in morphological shapes of shell artifacts from flaked edges to polished edges were possibly in coincidence with changes in use of drilling tools that were employed by flaked tools in the early period and by microblade tools in the late period,possibly suggesting a specialization of ornament production
