Abstract

Lead isotope ratios in horse-shaped bronze buckles excavated from the Songjeol-dong site in Cheongju and the mid-western region of the Korean Peninsula have been determined by thermal ionization mass spectrometry. The lead isotope ratios of the samples with data provenance were plotted in zone 3 of the South Korean galena map. The results indicated that the horse-shaped bronze buckles could be made using galena located in the same area as the archaeological site. These results can be used as basic data for comparison purposes in future studies on the manufacturing technology and provenance of bronze artifacts.

청주 송절동유적 출토 마형대구 29점의 납동위원소비 분석결과를 활용하여 납의 원료산지를 확인하고, 출토지와의 연관성을 확인하고자 하였다. 먼저 동북아시아 방연석 분포도(Mabuchi, 1985) 대입결과 대부분 중국 남부영역 내에서 매우 밀집한 분포 경향성을 나타내었으며, 한반도 납동위원소 분포도 적용결과 전라도와 충청도 지역에 해당하는 영남육괴 및 옥천변성대 지역인 Zone 3으로 확인되었다. 따라서 청주 송절동유적 출토 마형대구는 출토지와 유사한 지역에 위치한 방연석 광산에서 채취한 원료를 사용하여 제작하였을 것으로 볼 수 있다. 이와 함께 한반도 마형대구 출토 중심지역에 해당하는 중서부지역의 미호천유역 및 안성천유역 출토 마형대구 38점의 납동위원소비 분석결과와 비교하여 해당 문화권 내 마형대구 제작에 사용된 납 원료산지의 연관성 및 지역적 특성을 확인하였다. 향후 시대적 지역적 특성을 나타내는 마형대구를 대상으로 한 납동위원소비 분석결과를 축적하여 추가적인 원료산지 비교분석 연구를 통해 한반도 출토 마형대구의 납 원료산지에 대한 종합적인 정보를 얻을 수 있을 것으로 생각된다.
