Abstract

The social demands to conserve the geological outcrops with important scientific values are increasing. Accordingly public programs such as national geopark are recently established. In this study, outcrops with geological values in the Dusong Peninsula geosite of the Busan National Geopark are investigated in details with a discussion in the aspects of geoheritage values. The Dusong Peninsula is located in the late Cretaceous Dadaepo Basin interpreted as an intra-arc pull-apart basin extended in the Cretaceous Yucheon Subbasin. In this area, a number of noticeable geological records, such as andesitic sills, lower Dadaepo Formation, paleo-seismites, clastic dikes, compound calcrete deposits, syn-depositional normal faults, and unconformity between basin-fill and basements, are observed. Considering their unique geological significance, the strategic plans for their conservation and management should be urgently provided.

최근 지질학적 중요성을 가진 지질노두의 보존에 대한 사회적 인식이 확산됨에 따라 지질공원과 같은 다양한 제도적 장치가 마련되고 있으며, 지질노두들의 올바르고 체계적인 보존을 위한 지질학자들의 노력이 요구되고 있다. 이번 연구에서는 부산국가지질공원의 두송반도 지질명소에 분포하는 노두들을 대상으로 상세한 야외조사를 실시하고, 지질학적 중요성을 가지는 노두를 선별하여 이들에 대한 지질유산적 가치에 대해 논의하였다. 백악기말 유천소분지 내에 만들어진 당겨열림형 구조분지인 다대포분지 내에 위치하는 두송반도에는 안산암질 암상, 하부다대포층, 고지진암, 쇄설성암맥, 캘크리트복합층, 퇴적동시성 정단층, 분지기반암과의 부정합 등의 과학적 가치가 높은 지질노두들이 분포한다. 이들 노두들은 제각각 발달상태의 대표성, 전형성, 희소성 등에서 중요한 지질학적 의미를 지니고 있어 지질유산적 가치가 높으므로, 노두의 보호와 훼손방지를 위한 지속적인 보존 관리방안이 마련되어야 할 것이다.
