The role of collisional tectonics in the metallogeny of the Central Andean tin belt

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

“…Remarkably, the distribution of mineralization belts in SE China is analogous to metallogenic belts in South America (Sillitoe 1972a(Sillitoe , 1972bMlynarczyk and Williams-Jones 2005) (Figure 2B). South America hosts a succession of roughly parallel, N-S-trending metallogenic belts, which comprise four overlapping zones from W to E: the iron deposits of the Coastal Belt; the porphyry Cu-Mo-Au deposits of the Western Cordillera; the polymetallic vein-and replacement-type Cu-Pb-Zn-Ag deposits, and sedimentary Cu deposits of the Altiplano; and finally the vein and porphyry Sn-W-(Ag) deposits of the Eastern Cordillera (Sillitoe 1976;Mlynarczyk and Williams-Jones 2005).…”

This distribution of deposit types was explained as the result of a sequential incorporation of different metal suites in magmas generated at progressively greater depths above a shallow-dipping subduction zone below the Andean orogen (Sillitoe 1972b).…”

The formation of the Dabaoshan porphyry molybdenum deposit induced by slab rollback

“…Based on the age distribution of magmatic rocks and mineralization zonations in the Late Jurassic to the Early Cretaceous in SE China, an oblique subduction model was proposed to reconcile different lines of the observations (Wang et al, 2011b). The Nanling region was taken as the furthest mineralization belt associated with the southwestward subduction of the Pacific plate in the Jurassic (Wang et al, 2011b), with mineralization belt analogs to those in the South America (Mlynarczyk and Williams-Jones, 2005).…”

Mesozoic large scale magmatism and mineralization in South China: Preface

“…Both the W-Sn and Sb deposits are located in backarc settings away from the subduction zone (Mlynarczyk and Williams-Jones, 2005;Wang et al, 2011b). Multiple plate subductions in South China (Chu et al, 2012;Hua et al, 2005b;Li et al, 2012c;Wang et al, 2007Wang et al, , 2010Wang et al, , 2012bWong et al, 2009;Zhang et al, 2012) provided multiple events that enriched W, Sb and also Sn, F etc.…”

“…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 .…”
