Fig. 5. (A) Euler deconvolution technique are applied by using the residual gravity- (Fig. 4A) to obtain preliminary information on the 3D distribution of source points in the study area. The deep mass points greater than the mean depth (4,500 m), are mainly clustered in the western parts of the Dongducheon fault line marked with ①, while the eastern part of the Pocheon fault marked with ② is expected to be less than 4,000 m deep. Residual anomalies along the W-E profile (B) (refer to Fig. A for the location of the profile) ranges from –2.0 mGal to 6.0 mGal. The maximum source depth along the profile (D) are compared to the rock types (C).
