摘要
2004年5月初,在对延边和龙石人沟旧石器遗址的调查中,在山坡台地的黄色亚黏土和含黄色砂质土的角砾层内获得40件黑曜岩石制品,包括石核、石片、细石叶和使用石片、刮削器、雕刻器、琢背小刀等工具。遗址可能属于晚更新世的晚期,即旧石器时代晚期。
Forty stone artifacts were unearthed from the primary context of archaeological deposits at the Shirengou site, Helong county, Yanbian city of Jilin province. These objects include cores, flakes, microblades, used flakes, scrapers, burins and backed knives. Obsidian is the only raw material used for this stone assemblage. Major blanks for tools fabrication are flakes and blades. The principal flaking technique at the site is mainly direct hammer percussion, also indirect percussion. Modified tools appear to be retouched by direct hard hammer percussion, mostly soft hammer percussion, followed by pressure technique. According to the characteristics of this deposit （such as no polish on the stone artifacts, and no pottery） and the stratum yielding the stone artifacts,we suggest that the site is probably late Late Pleistocene or Late Paleolithic.
