“…In addition, hydrothermal K‐feldspars from the granite porphyry are characterized by a pronounced lanthanide tetrad effect, correlation between the Ca/Cl/K ratios and apparent ages, high contents of Ga, Ta, Nb, U, Y, and HREE, and low concentrations of Ba, Sr, Eu and Zr. All of these features suggest that metasomatic fluids played an important role in the formation of skarn mineralization (Li, Yonezu, et al, ). Previous studies (Li et al, ) obtained δ 18 O values of 4.3–5.0‰, 8.1‰, and 8.4‰ for hydrothermal fluids for the Cu, W–Mo, and Pb–Zn ores, respectively, suggesting diverse fluid sources.…”

“…However, this interpretation has been challenged by recent field investigations and geochemical studies that reclassified the Pb-Zn-(Ag) mineralization as being of sedimentary origin, with no direct relationship to Jurassic magmatism (Xi, Dai, & Liu, 2009;Zhu, Wang, Wang, Cheng, & Fu, 2012). Furthermore, fluid inclusion microthermometry yielded diverse results for different types of ores in the deposit (Huang et al, 2013), and Re-Os, Rb-Sr, 40 Ar-39 Ar, and hydrothermal zircon U-Pb dating of ore minerals suggested distinct ore-formation ages (~180-140 Ma; Jiang, Liu, Wu, et al, 2018;Li et al, 2014a;Li, Huang, Wang, & Wang, 2016;Li, Yonezu, Watanabe, & Tindell, 2017;Lu, Fu, Cheng, & Ma, 2015;Yao et al, 2007;Zhu et al, 2012). All of these results imply a complicated genesis for the Huangshaping deposit.…”

The Huangshaping world‐class W–Mo–Cu–Pb–Zn deposit formed during Jurassic intra‐continental extension in the central Nanling region (South Hunan), South China. In order to assess the role of fluids in ore genesis and the origin of polymetallic mineralization, three types of mineralized porphyries (quartz porphyry, granophyre, and granite porphyry) were studied. The multi‐method approach included whole‐rock Sr–Nd isotopic geochemistry and determination of the trace element content and gaseous and aqueous composition of ore minerals from the three stages of intrusion and ore emplacement. Geochemical results show that the Sr–Nd isotopes in these altered porphyries were strongly affected by fluid metasomatism. The 87Sr/86Sr and 147Sm/144Nd ratios for the quartz porphyry and granophyre range from 0.72894 to 0.83093 and 0.1524 to 0.2080, respectively, whereas higher and considerably more variable ratios were determined for the granite porphyry (0.90396 to 1.51943 and 0.2391 to 0.2914). These observations imply that granite porphyry‐associated W–Mo mineralization underwent more intensive fluid–rock interaction. The relatively low REE concentrations and high abundances of CH4 and H2 in the Cu ores associated with the quartz porphyry unambiguously suggest a deep‐sourced magmatic fluid for the Cu mineralization. The high REE concentrations, pronounced negative Eu anomalies, M‐type tetrad effects, and high CO2, H2O, and Ca2+ contents of the W–Mo ores associated with the granite porphyry imply that the W–Mo polymetallic mineralization was formed in a relatively oxidizing, high‐temperature environment with strong metasomatism. In contrast, the slightly negative Eu anomalies, W‐type tetrad effects, low CH4, and high F− and Cl− concentrations of the Pb–Zn ores indicate involvement of a sediment‐derived basinal brine and reducing mineralization conditions. Collectively, a three‐stage genetic model is proposed for the Huangshaping polymetallic deposit. Corresponding to initiation, development, and cessation of Jurassic intra‐continental extension, magmatic water, metasomatized fluids, and basinal brines played key sequential roles in Cu, W–Mo, and Pb–Zn mineralization.

“…Most of the W–Sn polymetallic deposits are located in the central Nanling Range, an area of ~6,600 km 2 in Hunan and Jiangxi provinces (Feng et al, ; Hu et al, ; Yuan et al, ). These deposits are typically enriched in W, Sn, Mo, Bi, Pb, Zn, Cu, Ag, Nb, and Ta, and in some areas, Pb and Zn are the dominant metals (Huang, Peng, Yang, Zhang, & Xu, ; Li, Yonezu, et al, ; Peng et al, ; Quan et al, ).

The Dengfuxian and Xitian ore fields, located in the central Nanling Range of South China, are characterized by multi‐stage W–Sn polymetallic mineralization. In this study, whole‐rock and zircon compositions in altered granites from four typical deposits in these ore fields (i.e., Dalong Pb–Zn, Xiangdong W, Gaolong fluorite, and Shaiheling Sn–Pb–Zn) were studied to constrain their fluid chemistry and mineralization history. Compared to unaltered granites at Dengfuxian and Xitian, these fluid‐altered granites are characterized by more variable SiO2 (64.2–78.4%) and lower TiO2 (0.02–0.12%), CaO (0.25–1.2%), and Na2O (0.31–2.6%) concentrations, lower ΣREE (87–156 ppm), and higher Zr/Hf (11.1–31.6) and Y/Ho (31.1–53.4) ratios, suggesting intense F‐rich fluid metasomatism. Zircon cathodoluminescence (CL), transmitted light and back‐scattered electron (BSE) imaging, laser ablation multi‐collector inductively coupled plasma mass spectrometry (LA‐MC‐ICP‐MS) trace‐element analysis, U–Pb dating, and Hf isotopes revealed a sequence of three W–Sn polymetallic mineralization stages: a Triassic stage (~220 Ma), a Jurassic stage (~150 Ma), and a Cretaceous stage (~80 Ma). The Triassic episode was associated with a highly fractionated granitic magma derived from the lower crust and contaminated by basement rocks; the magmatic fluid was affected by a high 176Hf/177Hf component from the ~770‐Ma basement and probably precipitated under high F and high fO2 conditions. The Jurassic episode was related to mantle–crust interaction and resulted in large‐scale W–Sn mineralization at decreased fO2. The Cretaceous episode was marked by Sn mineralization in a lithospheric extensional setting. We infer that basement rocks were the major source of metals for the world‐class W–Sn ore deposits in the Nanling Range of South China. This study also demonstrates that whole‐rock geochemistry of hydrothermally altered granites in combination with Lu–Hf isotopic, U–Pb dating, and trace element analyses of magmatic and hydrothermal zircons can be a useful approach to recognition of multi‐stage magmatic and mineralization processes.
