Horizontal slices of the 3D resistivity model for different depths: a 0.5 km, b 3 km, c 5 km, d 10 km, e 15 km, f 20 km, g 25 km, h 30 km, i 35 km. The RMS misfit of the 3D resistivity model is 1.03, and the number of iterations is 86. The white triangles in a represent magnetotelluric stations. The black solid lines depict active faults (Wang et al. 2017). The faults ①–⑥ are the same as those in Fig. 1b. C1–C3 represent the three conductive anomalous. Townships labeled in b include CK, Chaka; GD, Guide; SZY, Shazuyu; GH, Gonghe; HK Heka; XH, Xinghai; ML, Mangla; GN, Guinan and TD, Tongde. The magnetotelluric Profiles A1A1’ and B1B1’ in Ref. (Gao et al. 2020) is shown by the black dashed line in e. The solid arrows shown in f–h indicate the possible direction of the lower crustal channel flow, inferred from this study. WLGSZ labeled in c instead of Waliguanshan uplift belt, GHNS instead of Gonghenanshan
