Preliminary Study On Stone Products At Xingyang Jiangzhai Site,Henan Province

Most of the scholars in today's academic circles focus on one aspect of the study of stone tools,and few of them put their efforts into multi-method and multi-angle analysis and exploration,especially in the study of abrasive stone tools.Of course,this is not only because the stone tool research is difficult to operate in many aspects,and the researchers still have some stagnation in consciousness.However,the research methods of many scholars are more forward-looking,and it is an inevitable trend of stone tool research to integrate various methods.Previously,in the study of stone tools,especially the paleolithic artifacts,the analysis of stone tools involves the analysis of raw material,production process,micro-wear analysis and residue analysis etc.,and the heat treatment process is another focus of recent scholars.In general,many methods of stone tool research are mainly focused on knapping stone tools,while the research on abrasive stone tools is still in the initial stage,and the research methods and means of abrasive stone tools are mostly used for reference.However,most of the grinding marks in the process of grinding stone tools are difficult to observe,and it is also difficult to distinguish the micro-wear caused by actual use,so the analysis of the manufacturing process and using micro-wear is subject to many restrictions in the study of abrasive stone tools.In addition to the limitation of the use of traces and other trace related studies,excessive polishing even affects the naked eye identification,polishing marks change the original appearance of stone,so it is necessary to use XRD analysis and other means of material analysis to analyze its composition.There are still many difficulties in the study of abrasive stone tools,and the study of abrasive stone tools in historical period is faced with some new problems,due to the rich remain.From the Xingyang Jiangzhai site in Henan province,there are some differences between the use of agricultural tools by the ancestors in the West Zhou dynasty and the prehistoric period,such as the shape of tools,the way of use and the object of action.The stone dao and stone sickle of Jiangzhai site should be selected from local materials by XRD analysis.From the perspective of the objects of work done,there is no obvious difference between stone knife and stone sickle,and they are mainly used to reap yams,millet,coix,Triticeae etc.In addition,after the observation of micro-wear of excavated stone knife and stone sickle,as well as the comparative observation of simulated stone making and micro-wear,we can know the stone tool use mode of the ancestors of the West Zhou dynasty in this site.In the observation of the stone sickle,we can also find that there are too much left-handedness situations,which is a more significant difference compared with the right-handedness of more modern people.When the stone knifes and stone sickle analysed,we realised what stone tool use pattern the West Zhou dynasty ancients used,the most important thing is that the multi-method analysis is verified by the case study of the site.It is clear to see the necessity of comprehensive analysis,especially for the abrasive stone tools,compared with the single process and typological analysis,and the analysis of starch grains in integrated micro-wear after a variety of means,such as the stone tools of a site analysis can be more comprehensive and detailed.
