扬子克拉通北方边缘约500 km长的NE向江南钨矿带形成于140-150 Ma，总资源量约6.0 Mt WO 3。大多数矿床为与花岗岩有关的斑岩/脉型和夕卡岩型。该带西南部的竹溪、石门寺和石围洞三个大型W系是最重要的。这些矿床亲和力降低，与钛铁矿系列S型花岗岩有关。北东部许多规模较小的钨钼矿床具有氧化亲合性，与磁铁矿系列I型花岗岩有关。根据地质特征、岩浆形成温度、岩石和黑云母成分、Sr-Nd-Hf同位素数据和微量元素模拟，我们提出了一个由幔源基性岩浆侵入引起的地壳部分熔融形成的大的、还原的W型花岗质岩浆，随后内部岩浆演化的模式。相比之下，氧化程度更高的W-Mo相关花岗质岩浆是由地壳熔体和幔源镁铁质岩浆在热区的岩床混合形成的，岩浆演化程度较低。该模型解释了江南带同时代大型W矿床和小型W-Mo矿床的成矿特征，揭示了尽管总体地球动力学条件相同，但岩浆源区和相应的氧化态是导致还原型和氧化型钨系统之间存在显著规模差异的主要控制因素。
The 500 km-long NE-trending Jiangnan tungsten belt formed at 140–150 Ma at the northern margin of the Yangtze craton and has a total resource of approximately 6.0 Mt WO3. Most deposits are of granite-related porphyry/vein-style and skarn type. The three large W systems at Zhuxi, Shimensi and Shiweidong in the southwestern part of the belt are the most important. These deposits have reduced affinity and are related to ilmenite-series S-type granites. The many smaller W-Mo deposits in the northeastern part of the belt have oxidized affinity and are related to magnetite-series I-type granites. Based on geological features, magma formation temperatures, bulk-rock and biotite compositions, Sr-Nd-Hf isotope data and trace element modeling, we propose a model in which large, reduced W-related granitic magmas formed by crustal partial melting induced by intrusion of mantle-derived mafic magmas, followed by internal magmatic evolution. In contrast, the more oxidized W-Mo-related granitic magmas formed by hybridization of crustal melts and sills of mantle-derived mafic magma in hot zones, with minor magmatic evolution. This model explains the metallogenic features of the coeval large W and small W-Mo deposits in the Jiangnan belt and reveals that the magma source and corresponding oxidation state are the main controls on the significant size difference between the reduced and oxidized tungsten systems, although the general geodynamic situation is the same.
