青藏高原冬给措纳湖畔新发现的细石器及其同周边地区的技术关系

青海玛多冬给措纳湖畔新发现的海拔超过4000 m的全新世中期细石器对于我们认识青藏高原细石器乃至中国全新世的细石器的技术特点与分布格局提供了新的材料,其典型器物组合包括楔形细石核、柱形细石核、端刮器和锯齿刃器等。青藏高原全新世早中期的细石器组合中楔形细石核-柱形细石核-锥形细石核的技术传统是相对稳定的,但缺乏典型船形细石核和小型两面器等华北地区旧石器晚期细石器组合中常见的重要石器类型。通过进一步比对显示,青藏高原全新世早中期细石器的直接来源可能并非直承华北旧石器晚期的细石器传统,而与青藏高原邻近地区(我国西北地区、西南西区)全新世早中期的细石器工业具有更为密切的联系。

A new microblade assemblage from Dongjicuona Lakeside in the Qinghai-Tibet Plateau and its technological relationship with adjacent areas

The new find of a microblade assemblage from the Dongjicuona Lakeside in Qinghai Province above 4000 m elevation, which is dated to the Middle Holocene, provides new materials concerning the technological characteristics and distribution patterns of the microblade industry in the Qinghai-Tibet Plateau and even the whole of China during the Holocene. The lithic assemblage includes wedge-shaped microblade cores, cylindrical microblade cores, end-scrapers and denticulates. Overall, the wedge-shaped, cylindrical and conical microblade core assemblage was relatively common in Qinghai-Tibet Plateau during the Early and Middle Holocene, while the boat-shaped microblade core and biface which were common in North China during Upper Paleolithic were absent. Comparative study shows that the microblade industry of the Qinghai-Tibet Plateau during the Early and Middle Holocene may not directly originate from the North China, but instead this region had close contact with the microblade industry of the adjacent areas (Northwest and Southwest of China) during the Early and Middle Holocene.
