Study On The Stone Artifacts From Fifth Layer Of Lingjing Xuchang Man Site

The lingjing Xuchang Man Site located in the Central Plains region, which connects the north-south of China and east-west of the East Asian mainland, is a core region to explore the problems of stone tools industrial development during the transition period. However, limited by the few numbers of the sites which contain the continuous layers from middle Paleolithic, to Upper Paleolithic and Neolithic, the prehistoric research of the major academic subjects which mentioned above is hardly conducted. While Henan Institute of Cultural Relics and Archaeology excavated the Lingjing Xuchang Man Site during2005-2011. They revealed the strata in which distributed the layers from the Middle Paleolithic, Upper Paleolithic, to transition period of Paleolithic to Neolithic for the first time. Abundant stone artifacts, animal fossils and other artifacts have been unearthed from layer of each period. It is crucial to the research of the subject. The large number of stone artifacts, early potteries and other artifacts which unearthed from the5th layer,13,000to11,000B.P., belong to the sensitive period of Paleolithic and Neolithic transition. By researching the artifacts from the layer5, we can learn about the transition mode of the paleolithic to Neolithic, and try to answer the questions of the pottery origin. Besides, by comparing the artifacts from layer5, we can know more about the development history of the Ling Jing Xu Chang site during80-100thousand years B.P. chronologically. This dissertation consists of six parts.Chapter1. Introduction. Stating the purpose of this research and reviewing the history of researches, pointing out the research materials and methodologyChapter2. Introducting the standards on classification of stone artifacts and observating items.Chapter3. Analysis of stone artifacts. Classified the materials by typological methods, and observed all samples thoroughly to get more quantitative indicators. And then analyzed the quantitative data statistically to get the variety of data from ombinations of stone artifacts, we got the characteristics of this group of stone artifacts.Chapter4.Exploreing raw material utilizating strategies of ancient human being at Lingjing site.With the research of the blanks,processing methods.analysis the processing technology of stone tools.Chapter5.Discussion. First, compared the materials of this study with stone artifacts from lower and upper cultural layers, we got the chronological data of these materials. Then compared the stone artifacts of Lingjing site with the artifacts from the central plains region in upper Paleolithic period, we could explore the process of the stone artifacts industrial development from Paleolithic to Neolithic period in this region. Finally, by comparing and analyzing of the stone artifacts unearthed from the5th layer and artifacts from Lijiagou site, we explored the transition mode from Paleolithic to Neolithic in Central Plains.Chapter6. Conclusion.
