十里岗遗址石制品微痕初步研究

Preliminary Use-wear Studies on the Stone Artifacts of Shiligang Site

本文选择对十里岗遗址发掘出土的118件石片和5件工具标本进行了低倍法显微观察。其中36件标本有明确的使用微痕,4件标本有疑似装柄痕迹。共分辨出切割、锯、刮、削和刻划5种工具的运动方式,以切割和刮为主。加工材料类型以软性和中软性物质较多,中硬性和硬性物质较少。综合工具的使用方式和加工材料,推测肉类加工和皮革处理可能是当时遗址最主要的工作任务。

This paper studies the use-wear of 118 flaks and 5 stone tools excavated in Shiligang site through the low-power method.Among these,36 specimens recognize clear working use-wear,and 4 specimens possess uncertain hafting use-wears.There are five kinds of tool motions in these tools,such as cutting,sawing,shaving,scraping and graving.Cutting and scraping are the main tool motions.For the worked material,soft and medium soft materials are more than those medium hard or hard ones.Judging from these two aspects,meat-processing and leather-processing probably were the main work-task on the site.
