2018-2022年，安徽省文物考古研究所在安徽水阳江流域开展旧石器考古调查工作，新发现15处旧石器地点和采集点，复查既往发现遗址或地点6处，共获得116件石制品。石制品原料以石英岩占据统治地位，原料来源主要出自本地河漫滩上的砾石，标本表面普遍有一定程度的风化与磨蚀。石制品类型主要有石核和石片，硬锤直接锤击为主要剥片技术，较少使用两极技法剥片。石核根据剥片模式的差异可进一步分为尝试石核、砍砸器石核、盘状石核和多面体石核4类。各地点发现的石制品技术特征属于中国南方砾石石器工业。根据石制品出自网纹红土层或采集自网纹红土层地表的埋藏特点，初步推测这些地点的年代为中更新世。新发现为重新审视水阳江流域早期人类的石器技术提供了更多的考古学证据。

This report presents stone artifacts discovered in several Paleolithic surveys conducted from 2018 to 2022 in the Shuiyangjiang River Basin, Anhui Province. These investigations were done by the Institute of Archaeology and Cultural Relics of Anhui Province. A total of 15 new localities were discovered with six previous sites/localities confirmed. Lithic raw materials were procured from local riverbeds with quartzite as the dominant type of rock. Most stone artifacts were manufactured by freehand hammer percussion, followed by bipolar technique. Typologically, 116 lithic artifacts mainly cores and flakes. On basis of reduction patterns, cores could be separated into casual, chopper, discoidal or polyhedral cores. There were also some large tools such as heavy-duty scrapers and choppers. The whole lithic assemblage was assigned to the Pebble Tool Industry of South China. According to stone artifact location in vermiculated red soil and on the soil surface, it is reasonable to anticipate that early humans occupied these localities in the Middle Pleistocene. The archaeological evidence provides a new challenge in re-examining lithic technology from the Shuiyangjiang River Basin.
