(a) Th/Ta versus Th/Yb diagram showing the correlation between Huangling mafic dikes25, Yanbian maifc intrusions5 and Fanjingshan mafic rocks59, and Well W117 quartz monzonites. (b) Diagram of zircon saturation temperatures versus A/CNK ratios. The temperatures were estimated using zircon saturation thermometry53. The compared data for the granitoids are from Li et al.2 and Yao et al.17. (c) Barth mesonormative Qz–Ab–Or ternary diagram for the granitic rock. Contour diagram of mesonormative Qz, Ab and Or molecules of the plutonic rocks and its relationship to the pressure are after Parslow81.
