  • 국내에서는 자연 환경에서 발견되는 각종 지질 및 지형경관자원을 주 대상으로 내재적 가치를 이해시키고 자연보존을 촉진하는 지질관광에 대한 체계적이고 일관된 연구가 크게 부족한 실정이다. 본 연구는 관광지질학 활성화를 목적으로 지질관광 대상지역의 다양성 제고를 촉진하고 국립공원관리공단에서 제공하는 자연해설 프로그램의 다양화를 배가하기 위하여, 태안해안국립공원에 부존하는 지질 및 지형경관자원의 유형 및 분포상황을 조사하여 활용방안을 제시하는데 있다. 조사대상지역인 태안해안국립공원을 구성하는 지질 및 지형경관자원의 개체수 및 유형을 살펴보면, 총212개로서 해안지형$\rightarrow$풍화지형의 순서로 분포되어 있음을 알 수 있다. 상기 조사 자료는 지질학 및 지형학 전문가로 구성된 전문가집단과의 심도 있는 선별과정을 거쳐 일반대중에게 흥미와 과학의 이해를 돕는 지질관광 대상지역으로서 적극적으로 활용할 수 있을 것으로 사료된다. 아울러, 수요자 지향형의 지질관광대상지역 개발 활성화를 위해서는 지질 관광지역 방문객의 인구통계적 특성, 지질관광 대상지역에서의 방문객 행동특성, 지질관광대상지별 방문객 성별에 따른 방문객 행동성향비교 및 지질관광 프로그램 및 이벤트 개발을 위한 분석 등의 모니터링이 수반되어야 할 것이다. 그리고 지질관광 대상물에 대한 풍화도 평가 및 보존기술개발 등 지질공학적인 부분과 환경과학적 측면이 병행된 연구 노력이 이루어질 때 관광지질학의 활성화가 결실을 거둘 것으로 판단된다.

  • In this study, geomorphological and geological research has been carried out to estimate the possibility of ancient port location near Hwaseong Dangseong. Geomorphological characteristics around Eunsupo were analyzed through comparison of past and present topographic maps and field survey. Grain size, age dating, and geochemical analysis on surface sediments and borehole sediments were performed. Through the geomorphological characteristics analysis, it was interpreted that Eunsupo area was submerged in seawater especially at high tide in the past, and that ships could approach to the inside of the area through the tidal channel which were developed in the area. It is also assumed that ships were anchored at a low elevation point in the area. The paleo-environmental change in the area was analyzed based on the classification of sedimentary environment using grain size distribution of surface and borehole sediments and geochemical analysis. It was confirmed that the geomorphological interpretation for the possibility of ancient port location coincided well with the paleo-environmental change interpreted through sediment analysis. This study is a basic study for estimating ancient port location, and it is expected that more accurate paleo-environmental changes will be restored through detailed geomorphological survey and additional borehole analysis in the future research.

  • Geopark refers to a single boundary area consisting of a collection of geosites and geotrails, which includes ecological, historical and cultural elements based on geological and geomorphological resources. To ensure the continued development and conservation of existing listed geoparks, it is necessary to carry out an environmental sensitivity analysis of the geopark components by utilizing spatial information from various scales. The objectives of this study are to analyze the environmental sensitivity in Cheongsong UNESCO global geopark in relation with slope disaster using GIS and to understand its spatial distribution in connection with geosites and geotrails. Two types of spatial database were constructed; geosites and geotrails in Cheongsong UNESCO global geopark and spatial data to perform environmental sensitivity. Potential soil loss and slope stability were analyzed to derive environmental sensitivity related to slope hazard. The results showed relatively high environmental sensitivity along the drainage network of Cheongsong UNESCO global geopark. Zonal statistics analysis was conducted for further detailed distribution of environmental sensitivity based on buffer zones of geosites and geotrails. Majority of geological sites, geological trails, Jeolgol gorge~Jusan Pond section in hiking trails, and Dalgi Mineral Spring Site~Artistic Genius Republic of Korea(Jangnankki gonghwaguk) section in road areas show relatively high slope hazard sensitivity within buffer zones.

  • The objective of this study was two fold: firstly, we analyzed how the Geoparks have been run since the first one had been designated on December 31th, 2015. We then investigated how visitors' geographical and geological recognitions on the parks have changes. We visited geosites and investigated how well these sites accorded with the conditions for running Geoparks. In addition, scenery pictures and hashtags uploaded in Instagram between 2015 and 2016 were collected in order to analyze visitors preferences on the geosites along the, Hantan Imjingang River Geopark. Results showed that the hotspots were Bidulginang Waterall, Art Valley, and Jaein Waterfall. Compared to the ratio of geographical and geological references in 2015, the hashtags in all of these three geosites increased. The increases were as much as 3% in Bidulginang Falls, 0.6% in Art Valley, and 5% in Jaein Falls. In labelling the geographical and geological terms in Bidulginang Falls and Jaein Falls, the most frequently mentioned hashtags was "columnar joint", followed by "natural monument", "Geopark", and "basalt canyon". This study includes the study of visitors recognition which is one of the most important, but somehow neglected factor for the geopark's management.

  • This study documents the distribution of (active) faults around the southern part of the Yangsan Fault and the Moryang Fault and the middle part of the Dongrae Fault. For this objective, we extracted lineaments and fault-related landforms by analyzing aerial photos and digital elevation models and with the result of fieldwork on fault-relating features of the Quaternary landforms. Geomorphological techniques for active fault study are not only preliminary but also essential methods because, in general, an active fault can be defined only with fault-deformed Quaternary sediments when there is no way to detect precise timing of faulting. Therefore, geomorphological interpretation in active fault research is necessary to determine the extent, direction, termination and timing of fault. This study addresses the results of such geomorphological analysis and geomorphic markers for tracing the active faults in the study area. It is plan to investigate with geophysical and geological techniques the sites referred in this study.

  • There has been a lot of controversy over the claim that ancient characters were engraved on a stone plane collected near the Samsin Mountain in Hadong-gun, and that it was used as an altar based on the contents on the stone. The importance of the role of geoscience in prehistoric petroglyph research was presented through analysis and comparison with representative domestic petroglyphs. First, by examining the geological formation process of the collected stone objects, it proved that prehistoric actions were not applied. Second, as a result of comparative analysis from the viewpoints of human geography and topography with representative petroglyphs in Korea, it is unreasonable to argue that the stone was made for an altar. Third, it is considered that among the ancient characters under debate, the straight line indicates a cleavage of carbonate minerals, and the curved shape results from the growth of lichens. Finally, we propose that reproducing the lines found on the stone was impossible by using ancient techniques, and that there was no trace of any artificial actions applied to the spots considered to be curved characters. As shown in such research cases, the results of petroglyph research will have high reliability, if research by experts in each field continues after the geoscientific basis is secured. In this respect, the contribution of Earth science to cultural assets and archeology is expected to increase in the future.

  • This study analyzed the characteristics of the grain size distribution of the sediments obtained from the flooding in Ibang-myeon, Changnyeong-gun, which was caused by the collapse of a embarkment on the Nakdong River on August 9, 2020. As a results, it was found that the mean grain size decreases and the sorting becomes poorer as the distance from the embarkment collapse point increases. This is attributed to the fact that the transport energy of the river decreases when flooding occurs, ensuring that coarse-grained sediments are deposited first. Further, as the transport energy further reduces and becomes dispersed, the sorting for the fine-grained sediments becomes poor. Considering the characteristics of spatial distribution, sediments along the farm road showed the properties of floodplain deposits that transport to natural levee and back swamp due to river flooding. On the other hand, sediments along the irrigation ditch exhibited the properties of the deposits that are carried by the flow backward of ditch from the river after the collapse of the embarkment. The results of this study are significant because characteristics of flood sediments were elucidated for major rivers where flooding rarely occurs due to the recently built artificial structures. In addition, by applying the grain size distribution characteristics of present river flood sediments, it will be able to contribute to clarifying the sedimentary environments of the paleo river flood deposits.

  • Samples from two boreholes of coastal dune field at Jangho-ri coast, Gochang was studied. These were analyzed by grain size analysis geochemical analysis, and the application of OSL dating method to understand the development during the Holocene. The boreholes SB8 and SB9 were classified into three different sedimentary layers by their mean grain size and geochemical characteristics. The results revealed that the upper sand layer is equivalent to the present coastal dune layer, which developed since 1,200 years ago; the silt layer in the middle to the dune slack or lagoon sedimentation layer, which developed between 1,200 and 6,000 years ago; and the sand layer at the bottom to the paleo coastal dune that developed between 6,000 and 7,000 years ago. It was proposed that the forming material of current coastal dune was supplied from the sandy flat in coastal area, while the middle silt layer was supplied from the weathered soil of a bed rock by the comparison with material of surrounding area. In the case of coastal dune, concentrated layer of sands were identified which were buried about 300 and 1,200 years ago, which is identified as the little ice age. This study confirmed the development of Jangho-ri coastal dunes after Holocene Climate Optimum period, and it is likely to assist in the understanding of coastal dunes development.

  • 본 연구는 지라정보시스템과 원격탐사자료를 이용한 거시적 관찰과 현지답사를 통해 조선시대의 왕릉 분포지에 대해 형태적 특성과 외부 환경적 특성을 분석한 것이다. 조선시대 왕릉은 주로 호상편마암과 화강암 지질에 위치하며, 봉분은 남사면과 동사면에 주로 위치한다. 해발고도는 150미터에서 200미터 사이에 분포한다. 논리적인 풍수이론을 검증한 결과라기 보단 위성영상에 나타날 왕릉을 분석하여 현재 시점에서 입지를 관찰하게 되어 정확한 입지 요인을 도출하기는 한계가 있었다. 배산임수의 임(臨)이 얼마나 가까워야 하는지를 수량화 하는 것 자체가 매우 어려운 작업이고 지리정보분석의 결과로 평균 600미터 정도 떨어져 있는 하천은 의미가 없을 수 있다. 또한 광릉의 경우에서 보듯 상세한 지형지물의 관찰의 결과 왕릉은 인위적 훼손과 자연적 풍화와 침식에 오랫동안 노출되고 있었다. 사면분석과 경사분석 등의 지리정보 분석과 더불어 야외조사를 통해 지형형성과정을 관찰한 내용은 왕릉의 관리와 복원에 사용될 것이다.
