Abstract: 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.
