【摘要】：丹江口库区是国内发现的又一处阿舍利技术表现较为集中的区域。目前,该地区发现的旧石器旷野地点达100余处,其中经过发掘的地点有30余处。这些地点主要集中在丹江口库区规划淹没水位线以下区域,即汉江和丹江第二级和第三级阶地。为进一步探讨阿舍利技术在该地区出现的最早时间和起源方式等问题,我们对区域内第四级阶地进行了系统野外调查。新发现旧石器时代旷野地点24处,采集石制品273件,其中包括手斧、手镐和石刀等具有阿舍利技术风格的大型工具。研究表明,古人类在原料利用上具有选择性,脉石英主要用于生产中、小尺寸的石制品,而千枚岩和粗面岩主要用于加工阿舍利大型工具。不同类型石核反映了古人类在剥片策略上的多样性。加工技术方面,小型工具与大型工具共存,且不同类型的大型工具反映出较为完整的阿舍利工业器物组合面貌。
[Abstract]:Danjiangkou reservoir area is a more concentrated area of Asheli technology found in China. At present, more than 100 sites have been discovered in the Paleolithic wilderness, of which more than 30 have been excavated. These sites are mainly located below the planned submerged level in Danjiangkou reservoir area, namely the second and third terraces of Han River and Danjiang River. In order to explore the earliest time and origin mode of Asheli technique in this area, a systematic field investigation has been conducted on the fourth step of the region. Recently discovered 24 sites in the Paleolithic wilderness, collecting 273 pieces of stone, including axe, pickaxe, stone knife and other large-scale Asheli-style tools. The results show that the ancient humans were selective in the use of raw materials. Vein quartz was mainly used in the production of small-size stone products, while the 1000-rock and trachyte were mainly used in the processing of Asheley large-scale tools. Different types of stone nuclei reflect the diversity of ancient humans in stripping strategies. In processing technology, small-scale tools coexist with large-scale tools, and different types of large-scale tools reflect a relatively complete combination of Asheley industrial objects.
