摘要
2004年在丹江口库区发现并复查了43处旧石器旷野地点,共采集石制品367件。石制品包括石核、石片和石器,石器类型主要有刮削器、砍砸器、石球、手镐、手斧等。这些旷野地点分布在沿江两岸的第2、第3和第4级阶地上,时代从旧石器早期延续到晚期。各阶地的石器工业面貌较为一致,表现出以砾石及大中型石片加工而成的重型工具为主的特点。手镐、手斧等具有阿舍利技术特征的重型工具的发现,促使我们重新思考东、西方早期文化之间的异同,并为进一步探讨早期人类的迁徙、扩散和区域间的文化交流提供了重要材料。
Danjiangkou reservoir is located in the northwest of Hubei province and southwest of Henan province at the headwaters area of the Middle Route of the South-to-North Water Transfer Project. In October, 2004, the field team of IVPP conducted a survey around the margin of the reservoir that will later be submerged upon completing a new section of the dam. The present paper focuses on the study of 367 lithic artifacts collected from 43 open field sites, distributed upon different terraces along the Hanshui River and its tributary Danjiang River. Among them, 1 site was located on the forth terrace; 8 sites were located on the third terrace; 19 sites were located on the second terrace. Also 1 site was located on the third terrace of Danjiang tributary; 14 sites were located on the second terrace of this tributary. The Yunxian Man site, located on the forth terrace of Hanshui River was dated through faunal association and paleomagenetics methods at 0.83-0.87Ma BP. The deposites of the third terrace are red clay, containing cobbles and calcareous nodules. The develop of red clay in this region didn＇t reach the degree of the laterite weathering that was formed in strong weathering process of desiliceous and enriched bauxite, associated with the formation of gibbsite in Guangdong and Guangxi provinces. Instead, it corresponds roughly to the red soil weathering crust stage in southern China. Middle Pleistocene was the optimum weathering period in southern China where the northern boundary of the red soil weathering crust reached the south of the Qinling Mountain. The survey area is located in the north boundary of the red soil weathering crust, so its age should fall within the optimum period of the development of red weathering crust. The study of the loess-paleosol sequence showed that paleosol S5-S4 was an intense humid-warm stage in the Middle Pleistocene within the range of 0.7-0.4Ma BP. Because of this, we think the age of the third terrace maybe belongs to the early-to-middle Middle Pleistocene. The age of the seco
