Abstract

Sixty-four obsidian artifacts found in the Korean Peninsula have been characterised by a study of their minor elements and Sr isotope ratio. The artifacts are from the following locations: Yondaedo Island; Yokjido Island; Sangnodaedo Island, Tongyeong, Gyeongnam; Dongsamdong, Busan; Songdo Island, Yeosu, Jeonnam; Suyanggae, Danyang, Chungbuk; Sangmuyongri, Yanggu, Gangwondo; Paektusan Mountain; Kyushu region, Japan. The study of minor elements and Sr isotope ratio recognised three distinct major groups. This result suggests that there are no correlations among the three groups whose provenances are different. But as a result of classification using Sr isotope ratio, obsidian artifacts found in the southern part of the Korean Peninsula classified two groups within C group. This research will furnish scientific datum to be able to mutual comparison of obsidians excavated from other site.
