신안군 하태도 일대의 지형 및 지질경관 특성

Abstract

The purpose of this study is to investigate the characteristics of geomorphological and geological landscapes distributed in the Hataedo Area, Shinan-gun, Korea and to provide basic resources for geoscience education and geotourism. For the purpose of this study, geological surveying was carried out in the beach and rocky coast of the study area. The results of this study are as follows. According to the classification from the National Institute of Ecology(2019) and the categorization of the Korea Environment Institute(2003), geomorphological and geological landscapes distributed in the Hataedo area are classified into eight types and fourteen types, respectively. The eight types of geomorphological landscapes categorized by the National Institute of Ecology(2019) are sea cliffs, wave-cut platforms, notches, marine tafoni, marine potholes, gravel & sand beaches and mud flats. Similarly, the Korea Environment Institute (2003) classifies that rocky coasts, sea cliffs and wave-cut platforms as the general geomorphology of the study area. Stratifications, cross bedding, concretions, joints, dykes, volcanic rocks, conglomerates, sandstone, and shale in the study area are classified as general geological features. Characteristically, looking at the southern ocean from the forest road along the southern mountain ridge of Hataedong-ri, the view of several islands, large and small, at a glance is fine. A variety of geomorphological and geological landscapes distributed in the Hataedo area are worthy of material for geotourism and geoscience education. Jeollanam-do has been carrying out the project “ Making an island attractive to visitors” since 2015 to preserve ecosystems, landscapes, culture and the history of island belonging to Jeollanam-do; it also aims to unify the inhabitants of island with common goal in mind. As of 2020, 16 islands out of the total in Jeollanam-do have been designated as “ an island attractive to visitors”. The geomorphological and geological landscapes of Hataedo investigated and classified in the study could be used as base materials for assessment in order to be selected as an island for the project “ Making an island attractive to visitors”that Jeollanam-do has been conducting.
