Reflected and transmitted photomicrographs and cathodoluminescence (CL) images were taken of the zircon targets embedded in epoxy resin at Beijing Zirconia Navigation Technology Co., Ltd., Beijing, China. Zircon U-Pb isotopic dating was then conducted at Nanjing Normal University, Nanjing (NNU), China, and the State Key Laboratory of Continental Dynamics, Northwest University, Xi'an (SKLCD), China. Samples YAB-02, YAB-03, YAB-04, EGDB-05, and EGDB-06 were analysed at NNU using an Agilent 7700X ICP-MS system, while samples EGDB-01, EGDB-02, EGDB-03, EGDB-04, YAB-01, and YAB-05 were analysed at SKLCD using an Agilent 7500a ICP-MS system. The detailed operating process and data analysis methods were the same as those described by Yuan et al. (2004). When determining the zircon U-Pb ages, we used 206Pb/238U ages and 2σ values for zircon grains with ages younger than 1000 Ma and 207Pb/206Pb ages and 2σ values for zircon grains with ages older than 1000 Ma (Compston et al., 1992).
