Fig. 3. The complete Bouguer anomaly map (A) over the research area has a mean value of approximately –5.0 mGal and a range from –25.0 to 20.0 mGal. The higher Bouguer gravity anomalies relative to the mean value (–5.0 mGal) are generally observed to the west along the coast. The anomalies lower than the mean value (–5 mGal) reveal along the Chugaryoung fault system, where the Jurrasic Grantite are mainly exposed. ① – ⑦ : Fault lines (see Fig. 2 for the identifications). (B) The regional gravity anomalies are calculated using a wavelength of 20 km.
