本文是对2007年发掘获得的水洞沟第12地点石核类石制品的系统分析,研究对象包括锤击石核46件、砸击石核82件、细石核95件。通过对石核的尺寸、技术特征分析发现,锤击石核是细石核的预制阶段;砸击技术的开发对象多是以燧石为代表的优质石料,尺寸小,不适于锤击及间接剥片技术的应用;细石叶技术是该遗址的核心剥片技术,其中以楔形石核的打制技术最成体系。这种以细石叶技术为主体的文化现象,在旧石器时代晚期末段的中国北方地区具有普遍性,是人类在气候波动的条件下实现适应生存的重要技术保证。
This paper is a systematic analysis of the cores unearthed from the Shuidonggou Locality 12 in 2007, which includes 46 traditional flake technological cores, 82 bipolar cores, and 95 microcores. Based on the sizes and technological characters of the cores, it is reasonable to say that the flake cores are preparations of microcores. Bipolar technology is mainly used for working on smaller sizes or good quality raw materials represented by chert, which may not be suitable for direct/indirect flake technology. Microblade technology is key to this site with wedge-shaped microcores the most systematic. The phenomenon of microblade technology in North China during the Late Upper Paleolithic was widespread, and was the technologicalsupport for hunter-gatherers to subsist in the climatic fluctuations during the end of Pleistocene.
