Abstract: Shenquansi Palaeolithic site is located at 200m east of Shenquansi Village, Yanggao county, Shanxi Province. Its geographical position is 40°01′N, 113°52′E. The area of the site is around 100m2 and its age has been estimated about 18—11ka. B.P. .
The main raw materials used in the site are quartz and chalcedony. The main flaking technique is direct hard hammer percussion, and the bipolar technique was employed occasionally. Most flake platforms are medium or small in size, and most flakes have trapezoid forms. Most of tools are made on flakes; cores are rarely used as tool blanks, the tool class includes only scrapers and points. Most of scrapers are single-edged ones. A few elongated end scrapers are very characteristic, and a small-trihedral point is very similar to that found in Dingcun.
The implements are mostly modified by direct hard hammer, and they were retouched on the dorsal surface. Most edges of the tools are even, and most edge angles are measured between 60°-70°, but the end scrapers' edge engles are larger (between 80°-90°).
The artifacts belong to small types, the average size of the tools is 3. 5 ×3. 3 ×1. 4cm, while the average flake size is 3. 4 ×2. 6 ×1. 14cm.
Comparing with other sites, the authors consider the Shenquansi culture belongs to the main indus- try in north China, and cultural exchange might have happened among these industries in that time.
