This supporting material contains one text file (Texts S1), five supplementary tables (Table S1-S5), and three supplementary figures (Figure S1-S3). Text S1 describes the analytical methods employed in this paper. Table S1 presents the U-Pb analytical results of 342 detrital zircons from the six sandstone samples (K23-12, SJ-1, SJ-7-1, SJ-19, K24, and SJ-28). Table S2 lists the zircon U-Pb analytical results of the four volcanic rock samples (SJ-2, SJ-26, 13D1-6, and 13T3-3). Tables S3 presents the in-situ Lu-Hf isotopic analyses of 245 detrital zircons (<400 Ma) from the six sandstone samples. Compiled data are presented in Tables S4 and S5, which contain 153 radiometric ages of >300 Ma intermediate-felsic magmatic rocks (Table S4) and 566 Lu-Hf isotopes of crystallized and inherited zircons from the magmatic rocks (Table S5) in the Junggar and Yemaquan blocks. Figure S1 shows thecathodoluminescence (CL) images of representative zircon grains (a, b) andTh/U ratios versus U-Pb ages of zircons from the rocks in this study. Figure S2 displays the detrital zircon age distribution for individual sandstone sample used in this study.Figure S3 shows the spatial distribution (a) and the geochemical plots (b and c) of the Carboniferous rift and arc magmatic rocks in the Junggar and Yemaquan blocks.
