石人沟林场旧石器地点试掘报告

2007年8月, 对吉林延边和龙石人沟旧石器遗址周边进行考古调查时, 在石人沟林场东北的红旗河第2级阶地发现了该地点, 并进行了试掘, 面积为69m2。共获116件石制品, 其中出土86件, 采集30件。石制品包括石核、石片、细石叶、工具、断块及废片。根据地层堆积、石制品特征组合及与周边旧石器遗址对比分析, 推测该遗址的地质年代为晚更新世晚期。

A Report on the Excavation of the Linchang Paleolithic Site in Shirengou, Helong County

The Linchang Paleolithic site, buried in the second terrace of the Hongqi River, is located in the forestry center of the Shirengou village, Helong City, Jilin Province. The site excavation, which occurred in August - September 2007, exposed an area of some 69㎡. Nine stratigraphic layers of the second terrace were identified at the site, with the total thickness of about 2 meters. Stone artifacts (n =116) were unearthed, 86 from layers 3 and 4, and 30 from the surface.
The stone artifacts include cores ( n = 1 ), flakes ( n = 42 ), microblades ( n = 8 ), used flakes (n =5), chunks (n = 20), debris (n = 31) and retouched tools (n = 8). The general features of these stone artifacts are summarized as follows:
1)Obsidian is the major raw material used, constituting 97. 42% of the assemblage; a small amount of slate and tuff constituting 1. 72% and 0. 86% were utilized.
2) Most stone artifacts were small in size, followed by medium - sized.
3) Most blanks for tool fabrication were flakes (98. 62% ), followed by cores.
4) Modified tools appeared to be retouched by hard hammer percussion, followed by soft hammer percussion and pressure techniques. Tools were generally retouched on the dorsal surface.
5) Microblades accounted for 6. 91% of the stone artifacts; all were broken.
According to the characteristics of the stone artifacts, it can be inferred that this site showed close ties with the Upper Paleolithic Microblade Industry. The authors suggest that this site is probably a temporary camp for Upper Paleolithic humans.
