Abstract

It was estimated that wooden warehouses excavated from Bongseon-ri site in Seocheon were built around the 5th century according to the soil layers and construction methods of earthen structures. In order to identify the exact date, three wooden materials (BSMG 01, 06, and 12) from wooden warehouses were analyzed through radiocarbon dating using wiggle match. The outermost ring of BSMG 01 produced a radiocarbon date (95.4% confidence interval) of AD 431~551, BSMG 06 produced a date of AD 460~570, and BSMG 12 produced dates of either AD 240~430 or AD 490~510. The common age of the three wooden materials was identified as AD 490-510 and coincided with the original estimated archaeological age. Therefore, this study proved the accuracy of radiocarbon dating using wiggle match.

서천 봉선리 유적에서 출토된 목곽고의 제작 연대는 출토된 토층 및 토축부의 축조방법으로 5세기 전후로 추정되었다. 정확한 연대를 확인하고자 목곽부재 3점에 대해 위글매치를 이용한 방사성탄소연대분석을 실시하였다. 목곽부재 1(BSMG 01)의 최외각 연륜은 95.4% 신뢰구간에서 AD 431~551년, 목곽부재 2(BSMG 06)는 AD 460~570년으로 확인되었고 목곽부재 3(BSMG 12)은 AD 240~430년 또는 AD 490~510년으로 산출되었다. 목부재 3점의 공통 연대는 AD 490~510년으로 고고학적으로 추정된 연대와 일치하였으며, 위글매치를 이용한 방사성탄소연대측정의 정확성을 입증할 수 있었다.
