百峰遗址位于广西百色市田阳县境内,地处百色盆地右江南岸第四级阶地,地理坐标为23°45.399'N, 106°43.636'E, 是右江民族博物馆在2009年文物普查时新发现的一处旧石器时代遗址。共采集石制品27件。类型有石核、石片、手镐、砍砸器和刮削器, 其中手镐数量最多;原料来源于遗址附近第4级阶地的砾石层, 类别有石英岩、硅质岩、石英、粉砂岩和角砾岩5种, 以石英岩为主; 石制品以大型和中型为主; 剥片和修理方法主要为锤击法;石核剥片技术表现出剥片者对剥片过程的控制意识。根据地貌和地层推测该遗址年代为中更新世早期。

Palaeolithic Artifacts from the Baifeng Site at Baise, South China

Baifeng Paleolithic site was discovered at Tianyang County,Guangxi in 2009. It is located on the fourth terrace of the right side of the Youjiang River; its geographical position is 23° 45.399'N, 106° 43.636'E. During the survey, 27 stone artifacts were gathered from the surface, including cores(N=3), flakes(N=2), picks(N=14), choppers(N=5) and scrapers(N=3). Lithic raw materials were locally available from ancient riverbeds including quartzite(33%), argillite(22%), quartz(19%), farina sandstone(19%) and breccia(18.82%). Tool blanks were mostly pebbles as only two pick blanks were flakes. Most of the stone artifacts were large or medium in size, and modified by direct hammer percussion. According to typological analysis of these stone artifacts along with comparison to geomorphological and chronological details with other sites of the Baise Basin, we suggest that this site should date to the early Middle Pleistocene.
