고흥군 과역 서측 해안의 지형과 지질

Abstract

The purpose of this study is to provide a basic data for evaluation of the geoheritage values and the learning materials of earth science education for elementary and middle school students by the survey of geomorphology and geology at the western coast of Gwayeok, Goheung-gun. Also, relationships between the main learning contents in geology units of science class in 2015 curriculum and geomorphology and geology of study area were analysed. The results of this study are as follows. First, the coast of study area is about 180m in length, and composed of sea cliff, wave cut platform, gravel & sand beach and mud flat. The rocks exposed in outcrops of study area were conglomerate, sandstone, mudstone(shale) and tuff. And, it were observed that stratification, graded bedding, cross bedding, intrusion structure, fault, tafoni and spherical weathering and so on. Dykes is about 2m ∼ 5m in width, and is acidic to intermediate in composition. Fault observed in study area is normal fault of about 30cm to 40cm in displacement. Specially, it was showed that horst, relatively rising rock block formed by both side faults. Second, geology units of science in 2015 curriculum are “Change of earth surface”in 3rd grade, “stratum and fossil”, “volcano and earthquake”in 4th grade of elementary school and “change of solid earth”in 1st grade of middle school. it was comprehended that geomorphology and geology distributed in study area as mentioned above is very relevant to learning contents(coastal terrain, sedimentary rocks, fault, weathering phenomenon of tafoni and spherical weathering) in geology units of science class in 2015 curriculum. This study area are to be recommended as geological field trip course for elementary and middle school students inhabited in Goheung-gun, Bosung-gun and Suncheon-city from the perspective of accessibility. Development of programs for outdoor activity by school level is needed to use this area as a geological field trip course.
