Abstract

<p>Figure S1: Chondrite-normalized rare earth element (REE) distribution patterns of zircon grains from Yuanmou granodiorite, gabbros, and alkaline basalts. Figure S2: Zr versus elements diagram for the Yuanmou pluton and associated dike to evaluate post-crystallization mobility of major and trace elements. Figure S3: Harker diagram of Yuanmou adakitic and mafic rocks, magmatic evolution was simulated by using the software “Magma Chamber Simulator” with recharge and fractional crystallization (RFC) processes. Figure S4: Plots of εHf(t) versus εNd(t) diagram for the Neoproterozoic adakitic rocks from the western margin of the Yangtze Block. Table S1: Concordant results of zircon U-Pb ages for the Neoproterozoic Yuanmou granodiorite pluton and its mafic microgranular enclaves (MMEs) and associated dike. Table S2: The major analysis results of plagioclases for the Yuanmou granodiorites and MMEs and the major analysis results of amphiboles and clinopyroxenes for the Yuanmou MMEs. Table S3: The major and trace element analysis results for the Neoproterozoic adakitic, alkaline mafic and sub-alkaline mafic pluton in the western margin of the Yangtze Block. Table S4: The isotope results for the Neoproterozoic mafic and adakitic pluton in the western margin of the Yangtze Block. File S1: Original file of MCS.
