Abstract

<p>The purpose of this study is to analyze the geothermal anomaly based on the relationship between heat flow values and geologic settings in Sout Korea. For this, a total of 247 heat flow data was constructed to spatial database and the spatial database was overlaid with 1 : 1,000,000-scale digital geologic map using GIS. As the result, the average of heat flow os 64±14 mWm-2 in South Korea. In the lithogical aspect, the area of sedimentary rock shows high heat flow of 74 mWm-2, sedimentary/volcani rock area 62 mWm-2, plutonic rock area 63 mWm-2 and metamorrphic rock area 61 mWm-2. In the geologic time sequence, the Cenozoic strata has 91 mWm-2, the Mesozoic and Paleozoic strata 65mWm-2, the Proterozoic starta 55 mWm-2 and the Archean strata 61 mWm-2.

Keywords Geothermal, Heat flow, GIS, Lithology, Geolgical time
