A Study Of Stone Fragments From The Daban Site In Raohe

The Daban site is located on a platform about 15 meters above the Abujiao River in the east of Daban Village of the No.859 Farm,belonging to Raohe County,Shuangyashan City,Heilongjiang Province.This article takes the flakes in the stone products excavated in 2016 as the main research object,and tries to interpret the information of lithic artifacts in the site,the information of the site and the behavior patterns of ancient humans through the method of analyzing the pieces of the stones and the simulation experiment.This article mainly includes six parts:Chapter1:Introduction.Give a clear definition of the research object of this article,sort out the brief history of the research on the flakes at local and overseas and the current status of the research on the flakes in the Northeast,and explain the research methods and goals.Chapter2:Overview of the site.A brief review of the history of Paleolithic research in the Wusuli River Basin,and a brief description of the location,strata,types of unearthed stone products,cultural characteristics,and the age of the site.Chapter3:Analysis of flakes.Mainly observe and measure the flakes.of the preservation platform,and make detailed statistics on the shape of the flakes.,the attributes of the platform,the back and the ventral surface.According to the correlation of the attributes,the flakes are divided into two groups: Simulate the making experiment to verify the different stripping techniques embodied by the two kinds of flakes.Chapter4:simulation experiment.Before the start of the experiment,put forward the purpose of the experiment,and prepare the raw materials,tools,technology and other equipment for the experiment.Mainly carry out two experimental links:raw material testing and soft and hard hammer stripping.The soft and hard hammer stripping experiment is divided into four steps:soft hammer continuous stripping,hard hammer continuous stripping,stone core prefabrication stripping experiment and bifacial point making stripping experiment.The experimental process and results are recorded in detail.Through the analysis of the experimental results,the advantages and disadvantages of the raw materials are divided,and the soft and hard hammer pieces in the experimental specimens are compared.Chapter5:the comparison and discussion of experimental flakes and archaeological flakes.It is proved that there are not only soft and hard hammer stripping technology,but also bifacial point technique in the site through the research of the making technology,the purpose and operation chain and the ancient human behavior.There are two kinds of stone flakes: repair flakes in the process of making bifacial point and target flakes in the process of the core prefabrication.The nature of the site is a stone processing plant.Chapter6:conclusion.Summarizes the article and puts forward some shortcomings.
