한반도의 ‘아라야(荒屋)형새기개’ 기초 연구

Abstract

In the Late Upper Paleolithic period, a pressure technique appeared, whichshows development of tool making and a blade replacing technique whentheir blades of tools were blunt or damaged. That is, at that time, smallamount of raw materials were used to effectively maintain blades of tools. Microlithic and burin are representative remains of the Late UpperPaleolithic period, which was demonstrated in Araya Site of Japan. Inparticular, as it has been recognized that forms and techniques of Araya Sitewere distinctive, a formal name of ‘the Araya-type Burin was given to them. There are reports that this Araya-type burin was excavated from NortheastAsian areas such as Siberia and China and its distribution range is vast. Alsoin Korea, the Araya-type burin was excavated. 41 pieces of artefacts from 8Sites including Sangmuryongri, Yanggu were excavated. They were distributed over the central and southern part of Korea. Inparticular, they were mainly found in places where obsidian main part wasexcavated. 41 pieces of Araya-type burin were mainly made of obsidian, shaleand others(hornfels, rhyolite and Cmu₁) and are roughly categorized intoobsidian-type and rhyolite-type. It indicates that obsidian cluster of stoneartefacts was excavated from Araya-type burin and they are closely relatedeach other. Meanwhile, to closely examine the artefacts, microlithic-related stoneartefacts were excavated from all the sites, which is an evidence that burinand microlithic were used in the same period and place. In particular, Araya-type burin is characteristics by its unique technique. Itis composed of three stages of making blank, retouching platform and blade making. When the tools were blunt or damaged, the replacement processrepeated, which shows that the process was a distinctive method to use toolswith the economic concept of the Late Upper Paleolithic period.
