Table S1: (STS1) Samples collected near the study area; Table S2: Sample information from the shear zone and mélange zone: Table S3: (1) U-Pb isotope dates of magmatic zircons in granitic mylonites (11HYJ02 and 11QJJ01) from the Huoshishan ophiolitic mélange and the Qijiaojing shear zone. See Figure 2 for sample locations, (2) 40Ar/39Ar step-heating results of muscovites and biotite in granitic mylonites (11QJJ01, 11HYJ02, 11HYJ01-2, 11HYJ04 and 10TZHD03) from the Hongyangjing shear zone, the Huoshishan ophiolitic mélange, and the Qijiaojing shear zone. See Figure 2 for sample locations, (3) Methods：Methods divide into analytical method-EBSD (Electron backscatter diffraction), analytical method-U-Pb age dating, analytical method- 39Ar-40Ar age dating; Table S4. the raw data of 40Ar/39Ar from Institute of Geology and Geophysics, Chinese Academy of Science (IGGCAS) are given in the Supplementary data Table S4.
