百色盆地澄碧河库区含手斧遗址群调查及研究

广西百色盆地是我国南方最早发现和报道手斧的区域。狭义上的百色盆地位于右江干流的河谷地带，而广义上的百色盆地还包括了右江支流澄碧河流域的一部分（即澄碧河下游的澄碧河库区）。近期，由多家单位组成的联合科考队在澄碧河库区开展了野外调查工作，目前已在澄碧河第4级阶地上发现旧石器时代早期遗址18处，采集各类石制品300余件，另有60件玻璃陨石。值得关注的是，在其中的14处遗址中都发现了类似西方阿舍利技术的手斧工具，数量共计88件。澄碧河库区是目前百色盆地内手斧分布密度最高的地区之一，为深入探讨中国手斧工具的技术与形态特征，以及东西方古人类技术与文化的交流与传播提供了宝贵材料。玻璃陨石的发现表明，澄碧河库区含手斧遗址年代与目前已知的右江干流地区含手斧遗址的年代相近，处于早-中更新世过渡阶段。

Investigation and study of handaxe sites in the Chengbihe reservoir region,Baise Basin,Guangxi

The Baise Basin in Guangxi is an important region where handaxes were discovered and reported. In this study, we further report lithic assemblages found from the Chengbihe River Valley(i.e., the Chengbihe Reservoir Region), which is a tributary of the Youjiang River and can be regarded as a key sub-area of the Baise Basin. A joint research team has carried out field investigations in the Chengbihe Reservoir Region in recent years, and 18 early Paleolithic sites have been found on the fourth terrace of the Chengbihe River, along with the collection of more than 300 stone artifacts and approximately 60 tektites in the region. Importantly, a total of 88 handaxes were identified from 14 sites, making the Chengbihe Reservoir Region a rare and important region to study the evolution of handaxe technology in China and their possible connection with the West. The discovery of tektites shows that the age of handaxes found in the Chengbihe Reservoir Region can be placed to ca. 0.8 Ma.
