Geochemical diagrams for the Well W117 quartz monzonites: (a) K2O versus SiO2 diagram; (b) A/NK versus A/CNK diagram73; (c) Zr versus 10000 Ga/Al diagram74; (d) P2O5 versus SiO2 diagram for granites; (e) Chondrite normalized REE patterns; and (f) Primitive mantle normalized trace element spider diagrams. Chondrite and primitive mantle normalized values based on Sun and McDonough75. Data for the coeval Northern Guangxi granitoids in the eastern part of the Jiangnan Orogenic Belt are from Li et al.2 and Yao et al.17.
