Abstract: The Gonglou Paleolithic site was discovered at Tianyang county, Guangxi in 1980s, and was surveyed again in 2010. It is located on the fourth terrace of the south of Youjiang River, and the geographical position is 23°45.568 ?N, 106°42.210 ?E. Altogather 102 stone artifacts were gathered on surface, including cores(n=4), flakes(n=22), choppers(n=47) , picks(n=21), scrapers(n=6) and handaxe(n=1). Lithic raw materials exploited at the site were locally available from ancient riverbeds, and quartzite(43%), quartz (18%), silicalite(15%), siltstone(13%), fine sandstone(10%) and breccia(1%) were utilized in core reduction and tool manufacture. Blanks for tool fabrication are most cobbles. Most of the stone artifacts are large and middle in size; however, some cores, flakes, and scrapers are small. Tools are modified by direct hammer percussion. According to the comparison of Geomorphological with other sites of the Bose Basin, we suggest that this site should be close to the early Middle Pleistocene.
