초록

경상북도 봉화군과 강원도 삼척시에 걸쳐 드러나 있는 석개재 하부 고생대 퇴적지층 임도 및 도로 단면에는 전기 고생대 약 6천만 년 동안 퇴적된 태백층군의 모든 지층들이 연속적으로 드러나 있다. 지질학 분야에서 총 38편의 국내외 학술논문이 발표되었고 세계적인 학자들이 직접 방문하기도 한 석개재 단면은 학술적으로 중요한 곳임에 틀림없으나, 문화재 지정 논의도 이루어진 바 없고 최근 국가지질공원으로 인증된 강원고생대지질공원에도 포함되지 않았다. 천연기념물 지정 기준에 따른 평가 결과 석개재 단면은 다수의 항목에 충분히 부합하지만, 인위적으로 노출된 지질 단면일 뿐 아니라 지질 노두의 멸실 위험이 낮고 경미한 노두 훼손이 단면의 가치를 저해하지 않으며 경관적 가치가 낮기 때문에 문화재 지정의 당위성은 떨어진다. 최근 보완하여 제시된 지질유산 평가기준에 따른 평가결과 석개재 단면은 학술적, 교육적, 본질적, 기능적 가치가 매우 높으며, 지질유산 등급 분류기준에 따라 국가급 보호대상 지질유산에 해당한다. 현 제도 하에서 석개재 단면은 강원고생대지질공원에 포함되어 보전 활용하는 것이 가장 바람직하다. 석개재 단면의 경우를 통해 국가지질공원 신청 인증 과정의 보완이 필요함을 알 수 있으며, 향후 중요한 지질유산이 방치되지 않도록 제도개선 뿐 아니라 지질분야 연구자들의 적극적인 노력도 필요하다.

The Seokgaejae section is located along a timber access road and a driveway across Bonghwa County, North Gyeongsang Province, and Samcheog city, Gangwon Province. Its stratigraphic column shows all of the ten strata of the lower Paleozoic Taebaek Group, Joseon Supergroup. The Seokgaejae section is proved to be scientifically important. Thirty-eight domestic/international journal papers have been published on this early Paleozoic stratigraphic site, and many distinguished researchers over the world have visited the site. However, the section has never been considered to be designated as a national natural monument and was not included in the adjacent Gangwon Paleozoic National Geopark due to management or administrative issues. Although the Seokgaejae section sufficiently satisfies many of the national natural monument criteria, designation for the natural monument may not be justified because of the facts that the outcrop was artificially exposed by road construction; the chance of destruction of the outcrop is relatively few; demage on the outcrop to some extent does not impair the intrinsic value of the section; and the geomorphological/landscape value of the section is low. The application of the recently modified geological heritage assessment model to the Seokgaejae section shows very high scores on the scientific/educational, intrinsic, and functional values. Based on the improved geological heritage grade standard, the Seokgaejae section conforms to the national-level protection criteria. It is strongly recommended to manage the Seokgaejae section as a principal geosite by including it in the Gangwon Paleozoic National Geopark. This case study on the Seokgaejae section also suggests that the process of application and endorsement of a national geopark need further improvement. As well as the improvement of the system or policy related to geological heritages, further efforts of the experts in various fields of geoscience are required in order for other geological heritages not to be neglected from now on.
