Fig. 4. A residual anomaly map of the research area (A), which is calculated by subtracting the regional gravity field (Fig. 3B) from the Bouguer gravity field (Fig. 3A). The residual anomalies reflect the gravity effects of the crustal rocks much better than Bouguer anomalies (Fig. 3A). The dip curvature map (B) shows anticipated fault lines with a NE-SW direction (red dotted lines with aF2, aF5, aF8 and aF9) and a N-S direction (red dotted lines with aF1, aF3, aF4 and aF6). ① − ⑦ : Fault (see Fig. 2 for the identifications).
