虎头梁遗址中的细石器技术

Microlithic Technology from Hutouliang Site

本文从应用目的的角度出发,对虎头梁遗址中的细石器技术进行了界定。通过数量统计、模拟计算等方法论证了虎头梁遗址中共存在着2种细石器技术,它们分别以Ⅰ型细石核和Ⅱ型细石核为代表。这两种细石器技术体现出了不同的剥片效率以及古人类在对外部环境适应方面的不同需求。Ⅰ型细石核因其相对较高的剥片效率以及构思巧妙的外部形态、加工精细的刃缘具有石核和工具的双重功能,常被古人外出时携带使用。Ⅱ型细石核则是古人类仅用来在固定地点剥制细石叶而使用的。

In the paper microlithic technology is defined on the basis of studying microlithic materials from the Hutouliang site. By means of statistical analysis and model, the author considers that there are two microlithic technologies existed in the Hutouliang site： wedge-shaped core Ⅰ and Ⅱ. In comparison, the microblade detaching efficiency of Type Ⅰ cores are higher than the Type Ⅱ cores. Type Ⅰ cores have been recognized as a multi-functional artifacts that could have been used as tools such as scraper, point, drill, as well as microcore to produce microblades. Moreover, they could also have been carried along by prehistoric hunter-gatherers as part of provisioned toolkits, whereas Type Ⅱ cores only have been used as cores to detach microblades in living areas.
