Supplemental Material: Controls on metal fertility of dioritic intrusions in the Laiwu district, North China craton: Insights from whole-rock geochemistry and mineral compositions

Table S1: Major and trace elements geochemistry of whole-rock samples from the Fe-mineralized and barren dioritic intrusions in the Laiwu district. Table S2: Sr-Nd isotopic compositions of whole-rock samples from the Fe-mineralized and barren plutons in the Laiwu district. Table S3: Major and trace element compositions of amphibole from the Fe-mineralized and barren plutons in the Laiwu district. Table S4: U-Pb age data and trace elements of zircon from the Fe-mineralized and barren plutons in the Laiwu district. Table S5: Major and trace elements of apatite from the Fe-mineralized and barren plutons in the Laiwu district. Figure S1: Hand specimens of diorites were collected from the Kuangshan (A), Jiaoyu (B), Jinniushan (C), and Tietonggou plutons (D). Figure S2: CL images of representative zircons from the Kuangshan (A), Jiaoyu (B), Jinniushan (C), and Tietonggou diorite (D). Scale bar is 100 μm. Figure S3: U-Pb Concordia diagrams of zircons from the Kuangshan (A), Jiaoyu (B), Jinniushan (C), and Tietonggou plutons (D). The insets in each diagram are the weighted mean 206Pb/238U age. Figure S4: Selected oxide element Harker’s plots for the Fe-mineralized and barren plutons 20 in the Laiwu district.
