河南淅川丹江口库区马岭2号地点B区发现的石制品

Lithic Assemblage from the Maling Locality 2B in the Danjiangkou Reservoir of Xichuan County, Henan Province

马岭2号地点B区位于河南省淅川县盛湾乡贾湾村马岭,遗物埋藏于丹江右岸第三纪基座阶地的黏土层中。2011年4~5月和2012年3~4月,中国人民大学历史学院等单位对该地点进行了抢救性发掘,发掘面积1700平方米,出土石制品770件。石制品类型包括石核、石片、石锤、两面器、石核砍砸器、石核刮削器等,古人类选用阶地底部砾石层、河滩砾石中的磨圆砾石为原料,石英岩所占比重最高。剥片和修理技术为硬锤直接锤击法,以较大尺寸的毛坯为主要加工对象,两面器有相对稳定的生产体系,石器组合上似阿舍利技术面貌。通过与周边遗址比较,其年代应处于中更新世晚期。

The Maling locality 2B, buried in the front margin of the third terrace on the right bank of the Danjiang River, is located in Jiawan Village, Shengwan Township, Xichuan County, Henan Province. In April to May 2011 and March to April 2012, the Renmin University of China’s School of History and other units carried out rescue excavations at the Maling locality 2B, revealing 770 lithic tools from an excavation area of 1700 m2. The unearthed lithic assemblage consists of cores, flakes, bifaces, chopper cores, scrapers, etc. Most of the lithic raw materials were locally procured from ancient riverbeds, and quartzite is the predominant raw material. Direct hard hammer percussion without core preparation is the principal flaking technique. Chopper core is the main type of core. Bifaces suggest a relatively stable production system and the lithic assemblage show characteristics of the Acheulean-like industry. We suggest that the site date to the later phase of the Middle Pleistocene.
