본 연구는 대도심에 위치하는 야산을 지질학습장으로 활용할 수 있는가에 대한 조사이다. 이를 위해 광주광역시 서구에 위치한 높이 305 m의 금당산을 대상으로 인문 및 자연지리, 지질학적 특성, 지형요소, 경관, 야외학습을 위한 편의성 등을 검토하였다. 금당산 주변의 반경 5 km 이내에 거주하는 인구는 약 62만 명 정도이며, 이 중 학생과 교원은 약 17만 명이다. 연구지역은 강수일이 적고, 온화한 날씨가 많아 학습장으로 활용하기에 적합한 기후를 가지고 있다. 금당산에 접근하는 도로망과 대중교통도 매우 편리하다. 금당산에서는 다양한 암석과 지질구조를 관찰할 수 있다. 연구지역의 기반을 이루는 광주화강암은 중생대 쥐라기의 심성암체이다. 이 지역에는 백악기의 그래노파이어(미문상화강암)와 층상응회암, 라피리응회암, 유문암과 같은 여러 가지 화산암이 분포한다. 다양한 중성 및 산성 암맥이 절리를 따라 관입하고 있다. 금당산에는 U자형의 지형, 다양한 크기와 방향의 절리, 단층, 엽리, 나마, 토르, 단애, 그루브, 암괴류, 암괴원, 풍화층과 새프롤라이트와 같은 다양한 지형요소가 있다. 금당산 주능선에서는 무등산 전체 모습과 시가지 전경, 풍암 호수와 월드컵경기장, 일출과 석양과 같은 아름다운 경관을 감상할 수 있다. 또한 지질학과 연계할 수 있는 생태 학습 시설이나, 야외학습을 위한 편의시설이나 응급의료시설도 잘 갖추어져 있다. 결론적으로 금당산은 지질학습장으로서 매우 양호한 조건을 갖추고 있다.

Abstract

The purpose of this study is to investigate a feasibility of a small mountain as a field work site on geologicalfeatures in Earth sciences classes at all levels. Mt. Geumdang with the height of 305 meters from the sea level is locatedin the metropolitan city of Gwangju, southern part of Korea. The study reviews the human and natural geography,geological features, geomorphic resources, landscapes, and conveniences of the mountain for a possibility of meaningfulfield work. The population within the distance of 5 km from the mountain stands at about 620,000 and 170,000 of themare students and teachers. Mt. Geumdang has a warm temperature climate with low rainfall throughout the year, so itseems suitable for a field survey. Road network and public transportation system around the area are well developed andeasily accessible. Mt. Geumdang shows various rock type and geological structures. The basement rock is Gwangjugranite, which is plutonic body of the Jurassic period. Also, granophyre (micrographic granite) and various volcanic rocksdistributed as bedded tuff, lapilli tuff, and rhyolite of the Cretaceous period. Many andesitic and felsic dykes wereintruded into the rock by joint system. In Mt. Geumdang, many geomorphic resources are found such as U shapedmountain, joint, fault, lamination, gnamma, tor, cliff, groove, block stream and block field, regolith, and saprolite. It has abeautiful mountain scenery including the view of whole shape of Mt. Mudeung, panoramic view of the town, Pungamlake, World Cup stadium and sunrise and sunset. Furthermore, the area has ecologic study facilities related to geology,emergency medical and convenience facilities for field works. In conclusion, Mt. Geumdang is highly feasible forgeological field studies at all levels.
