Research On The Assembly Of Stone Products At The Huayang Site In Yichun And Related Issues

Located in Nancha County,Yichun City,Heilongjiang Province,the Huayang site is one of the most important prehistoric sites found in the Heilongjiang region in recent years.In this paper,taking the stone artifacts of the second cultural layer of the main excavation area in 2012 as the research object,through the mosaic research,the stone tool making technology,site burial and space utilization strategy are discussed.This article mainly includes five parts:Chapter 1.A brief description of the discovery process,geographical location,stratigraphic conditions,raw materials,types and cultural characteristics of the Huayang site in Yichun,as well as the age of the site,is given.The research status of stone product assembly,and the different stages of stone product assembly are divided,and the purpose and significance of the study are explained at the same time.Chapter 2: Overview of the Flattening Process and Results.The process and results of this stone product splicing are elaborated,including the conditions,process and time planning of the splicing,and the results are summarized in terms of raw materials,the number of specimens in the combination,and the characteristics of rupture.Chapter 3: Planar Distribution and Technical Analysis of Stitched Specimens.Based on the planar distribution of the flat group and combined with the density distribution of stone products in the site,the plane distribution positions of various flattening groups of nepheline,strip rhyolite,filament porphyry,crystal tuff,Ying'an rock and shale raw materials were divided into regions,and then the technical process and the correspondence of plane distribution of the stone products of the conjunct group in a single area were analyzed.Chapter 4: Based on the results of the mosaic analysis,it focuses on the burial process of the site and the spatial use of the site.Combining the geological parameters and the parameters of archaeological relics,it is demonstrated that the site is less hydrodynamically transformed and has the nature of burial in situ;the space utilization of the site can be divided into four stone tool block groups,and the technical activities dominated by each block group and the selection and utilization of different raw materials have an "overlapping" space utilization strategy.Chapter 5: Finally,summarize the article.
