Abstract

We analyzed the provenance and petrographic characteristics for the rock properties from stone-lined tomb and stone chamber tomb at the Dorim-ri site of the Baekje Kingdom, located in Cheonan. The two tombs consist of 10 kinds of rocks including gneiss, diorite, and andesite. The major rock type is gneiss (54.3%), which composes the main chamber walls of the tombs. Diorite (11.3%) and andesite (10.6%) also make up a large percentage of the rocks, tending to be used to fill the space between the main chamber walls. Thus, the stones appear to have been used according to their shape and the disposition of the site, respectively. Investigation of their provenance, confirmed their source area to be near the Ipjang Reservoir, about 1 km away from the site, and their procurement was probably conducted via a waterway. This result might serve as basic data regarding the material procurement system of ancient tomb culture and for preservation measures for archaeological sites.

이 연구에서는 천안 도림리 유적 출토 백제시대 석곽묘와 석실분의 구성암석에 대한 암석기 재적 특성과 원산지를 분석하였다. 이 두 분묘는 편마암과 섬록암 및 안산암을 비롯한 총 10종의 다양한 석재로 구성되어 있다. 특히 편마암이 가장 높은 점유율(54.3%)을 보이며, 벽석의 주요 석재로 사용되었다. 또한 섬록암(11.3%)과 안산암(10.6%)은 사잇돌로 사용된 경향을 보여, 형태와 상황에 맞게 석재를 활용한 것으로 판단된다. 석재의 공급지는 유적과 약 1 km 떨어진 입장저수지 인근으로 확인되었고, 수로를 통해 조달했을 것으로 해석된다. 이 결과는 고대 분묘문화의 재료조달 체계와 유구의 보존을 위한 기초자료로 활용할 수 있을 것이다.
