中文摘要：

六合遗址位于百色盆地右江南岸第4级阶地上，于2005年6月至11月进行了抢救性发掘，揭露面积1000m2。遗址地层分为5层，其中第①、②和③层为次生堆积，第④层为原生的网纹红土，第⑤层为砾石层。本次发掘出土71件文化遗物，包括磨制石器2件、打制石器69件；此外还发现1件玻璃陨石。打制石器以大型和中型为主，包括石核、石片、工具、断块等，以断块居多；工具类型有砍砸器和手镐。石制品原料采自遗址附近第4级阶地砾石层，有石英岩、角砾岩、细砂岩、硅质岩、中砂岩和石英，以石英岩为主。根据出土的玻璃陨石，并结合地层、石制品特征比较，六合遗址打制石器的年代可能为中更新世早期。

英文摘要：

The Liuhe site, located on the fourth terrace of the Youjiang River, was excavated from June to November, 2005, which was a salvage archeological project for the anticipated construction of the Bose-Nanning Expressway. The excavations exposed an area of 1000m2. A total of 72 relics were discovered, including 2 neoliths, 69 paleoliths and 1 tektite. The paleoliths include cores（N=4）, flakes（N=5）, tools（N=14） and chunks（N=46）. The tools appear with choppers（N=12）and picks（N=2）. Lithic raw materials of the industry were exploited locally from ancient riverbeds. Quartzite（53.61%）, breccia（18.82%）, fine Sandstone（7.37%）, silicolites （5.80%）, medium Sandstone（2.90%） and Quartz（1.45%） were utilized in core reduction and tool manufacture, with Quartzite the predominant type. Blanks for tool fabrication are pebbles. Most of the stone artifacts are large and middle in size, and modified by direct hammer percussion. The stone tool assemblage of the Liuhe site shows close association with the lithic industry in Bose. Geomorphological and chronological comparison with other sites in Bose Basin indicates that the age of the paleoliths of Liuhe site should be close to the early Middle Pleistocene.
