Fig. 2. The geological map of the study area shows that the Chugaryung fault system is mainly covered by Precambrian Gneiss, Jurassic Granites and Cretaceous volcanics. About 100 density measurements of igneous, metamorphic, and volcanic rocks are indicated by symbols that relate to the observed values (Park et al., 2009). The mean densities of the Granites, Volcanics and Gneiss are measured of 2.60, 2.56 and 2.67 g/cm3, respectively. ① –⑦ : Fault lines (see Fig. 2 for the identifications).
