전라남도 득량만 북측 해안에 분포하는 지질노두의 지질유산적 가치

Abstract

The aim of this study is to evaluate geoheritage values, and describe geological records in the geological outcrops distributed in the north coast of Deungnyangman, Jeollanamdo. The results of this study are listed below. Various geological records are distributed in the geological outcrops of about 1.2km coast of this study area. The area shows unconformity that involves a substantial break or gap in geological record, and meets with a fracture caused by spheroidal weathering and the intrusion of acidic and intermediate dykes in the 5 sites of this study area The explanations on geological records of this investigation are as follows. The unconformity of this study area is a nonconformity developed between sedimentary rocks and older metamorphic rock. The fault (about 2m displacement) showed in this area is mainly a normal fault developed in sedimentary rocks. The phenomenon of spheroidal weathering, which is a product of chemical weathering is developed in the outcrops of igneous and gneiss. The acidic and intermediate dykes around 3m to 5m in width are developed in the outcrops of gneiss. As for the geological records of these 5 sites, the values of academy, education, geomorphology and landscape were evaluated as excellent. This is due to the representativeness, scarcity and diversity of these geological outcrops. As this study indicates, these 5 sites have high value as geoheritages and thus, plans for the conservation and management on these geological outcrops should be provided.
