 Figure S1: Representative field photos and microscopic photographs of mafic rocks in this study. Figure S2: Plot of whole-rock εNd(t) versus age (Ga) for the Boka dolerites, Lanniping gabbros, and Tong’an dikes. Figure S3: Covariations of the high field strength elements (e.g., TiO2, Th, Nb, Nd, Eu, Yb), compatible element (e.g., Ni), and large ion lithophile elements (e.g., Ba and Sr) relative to Zr contents for the Boka dolerites, Lanniping gabbros, and Tong’an dikes. Figure S4: Covariations of SiO2, TiO2, Fe2O3T, CaO, Al2O3, CaO/Al2O3, P2O5, Ni, and Cr relative to MgO contents for the Boka dolerites, Lanniping gabbros, and Tong’an dikes. Figure S5: Th/Nb versus TiO2/Yb plot for the late Mesoproterozoic mafic rocks in the southwestern Yangtze Block. Table S1: Cameca secondary ion mass spectrometry (SIMS) zircon and baddeleyite U-Pb isotopic analyses for the late Mesoproterozoic mafic rocks from the Huili-Dongchuan area, southwestern Yangtze Block. Table S2: Major-element (wt%) and trace-element (ppm) data of the late Mesoproterozoic mafic rocks from the southwestern Yangtze Block. Table S3: Sm-Nd isotopic compositions of the late Mesoproterozoic mafic rocks from the southwestern Yangtze Block.
