Research On Stone Artifacts From Yiduquan Site In Nihewan Basin,Hebei Province

In 1984,the Hebei Provincial Institute of Cultural Relics and Archaeology organized a special survey of Paleolithic artifacts and discovered the site of Yiduquan,collecting 44 stone artifact.2019,the Hebei Provincial Institute of Cultural Relics and Archaeology and the Management Committee of the Hebei Nihewan Site Cluster Protection Area organized a team to organize a special survey of Paleolithic artifacts in the area around Yiduquan and excavated the site,and a total of 271 pieces of stone artifacts were excavated in this excavation,along with a certain number of animal bones.The research object of this paper is the 271 stone artifacts obtained from the excavation in 2019,and the production sequence of stone artifacts is recovered using The results of the study show that the raw materials of stone products at the Yiduquan site are mainly quartz and flint,and the stones are mostly quarried from the river floodplain near the site;the types of stone assemble include cores,flakes,chunks,and tools;hammered stone cores and bipolar stone cores are observed at the site,but the overall utilization rate is not high;the tools are mostly flake blanks,with small and medium sizes,and the retouch method is hammering,and the processing method is mainly positive processing,with scarification The number of layers is 1-2,and the processing position is mostly located on the side.The carbon 14 dating of this site is about 3 to 4 ka B.P.,which belongs to the late Paleolithic period.A comparison with several Late Paleolithic sites in the Nihewan Basin and the North China region shows that the overall lithic industry of the Yiduquan site is more typical of the northern small stone industry,and there may be some connection with the West Baimaying and Panjingzi sites in the same Nihewan region.This comprehensive study of lithic artifacts from the Yiduquan site provides new clues for exploring the relationship between two different types of lithic industries in the late Paleolithic period in the Nihewan area and for refining the Paleolithic cultural chronology of the area.
