Mesozoic large magmatic events and mineralization in SE China: oblique subduction of the Pacific plate

High Oxygen Fugacity and Slab Melting Linked to Cu Mineralization: Evidence from Dexing Porphyry Copper Deposits, Southeastern China

“…This is compatible with recent models that attribute the Jurassic large-scale igneous event and associated mineralization in southeastern China to plate subduction (Zhou and Li 2000;Wang et al 2011b). On the basis of the drifting direction of the Pacific Plate (Sun et al 2007a;Wang et al 2011b) and the Dexing and LYRB magmatic activity period, we locate the subduction zone to the northeast of the South China block. Previous authors have proposed that southeastern China became an active continental margin in the Jurassic or even earlier (Maruyama 1997;Zhou and Li 2000;Scotese 2002;Sun et al 2007a).…”

Qian'echong low-F porphyry Mo deposits in the Dabie Mountains, central China

“…It is a reliable geothermometer and also a good recorder of oxygen fugacity (Ballard et al, 2002;Bolhar et al, 2008;Liang et al, 2006;Wang et al, 2011a;Wang et al, 2011b).…”

Mesozoic large scale magmatism and mineralization in South China: Preface

“…The Dexing porphyry CuMo-Au and Xiang-Gan Pb-Zn-Ag deposit regions are located between the Nanling and Lower Yangtze River belts (Hua et al, 2005b;Li and Sasaki, 2007;Li et al, 2007a;Wang et al, 2006b;Wang et al, 2011b;Zaw et al, 2007), which are analogous to subduction related mineralization belts in South America ( Fig. 1) (Mlynarczyk and Williams-Jones, 2005;Wang et al, 2011b). Most of these deposits are closely associated with a large igneous event in South China that started in the Jurassic and ended in the Cretaceous .…”

“…1), the Nanling W-Sn, Nb-Ta, HREE belt in the south (Chen et al, 1992;Guo et al, 2011;Hsu, 1943;Hu et al, 2009;Hua et al, 2005a;Mao et al, 2007), the Lower Yangtze River Cu-polymetallic, iron oxide copper gold belt in the north (Deng et al, 2011;Mao et al, 2006;Pan and Dong, 1999;Sun et al, 2003;Yang and Lee, 2011; and the Xiang-Qian-Gui Sb belt in the west (Peng et al, 2003;Wu, 1993;Yang et al, 2006;Zaw et al, 2007). The Dexing porphyry CuMo-Au and Xiang-Gan Pb-Zn-Ag deposit regions are located between the Nanling and Lower Yangtze River belts (Hua et al, 2005b;Li and Sasaki, 2007;Li et al, 2007a;Wang et al, 2006b;Wang et al, 2011b;Zaw et al, 2007), which are analogous to subduction related mineralization belts in South America ( Fig. 1) (Mlynarczyk and Williams-Jones, 2005;Wang et al, 2011b).…”
