A gravity and magnetic study of lithospheric architecture and structures of South China with implications for the distribution of plutons and mineral systems of the main metallogenic belts

South China is characterized by enormous volumes of igneous rocks generated multiple stages magmatism. Five large-scale metallogenic belts with many world-class deposits have been discovered, demonstrating great potential for prospecting new resources. To restrict the cognition main problems include types and metal associations deposits, factors controlling distribution different belts, targets deposits. find possible feasible solutions to solve these problems. It necessary consider from concept mineral systems. This study first converted satellite gravity into Bouguer under spherical coordinates. Then reduction-to-the pole (RTP) magnetic anomalies were obtained using a moving window geomagnetic parameters. The vertical lithospheric interfaces faults inverted interpreted according data. Based on results obtained, we discussed sources pathways five in China. Meanwhile, it identified 3D spatial intrusions qualitatively susceptibility density model, predicted sites Cu, Fe, Au, W, Sn
