“…The second stage of mineralization (170-150 Ma) is the most important metallogenic period in South China, mainly in the metallogenic belt of Qinhang, forming large-scale, multitype, high-grade tungsten, tin, molybdenum, antimony, copper, zinc, gold, and silver polymetallic deposits, widely distributed in southern Jiangxi, northern Guangdong, southern Hunan, and northeast Guangxi (e.g. Mao et al, 2013;Li et al, 2018). The 120-80 Ma period was the third metallogenic period in South China (e.g.…”

The Xihuashan and Tieshanlong tungsten deposit is an important large quartz vein‐type W‐polymetallic deposit in the southern Jiangxi Province, eastern Nanling Range. Zircon U–Pb analyses of representative ore‐forming granites from the Xihuashan and Tieshanlong tungsten deposit yield ages of 146.3 ± 2.9 Ma and 146.0 ± 3.8 Ma, respectively. According to the zircon Raman spectroscopy, these granitic rocks are disturbed by different degrees of hydrothermal alteration, whereas most zircons exhibit primary oscillatory zoning and Th/U ratios in the range of magmatic zircon, which means the analysis results represent the crystallization age of metallogenetic granitic assemblages. In combination with regional geological data, it is suggested that the Late Jurassic is probably another important episode of granitic magmatism and W‐Sn mineralization in southern Jiangxi Provinces, even South China.

“…The Huangshaping polymetallic deposit is located close to Chenzhou City in the southern Hunan Province (Figure ). The South Hunan W–Mo–Cu–Pb–Zn ore belt is the most important part of the Nanling tectono‐magmatic belt in South China, which hosts complex geologic structures, experienced multiple magmatic events (Kong et al, ; Mao, Cheng, Chen, & Pirajno, ), and has a rich base‐metal and nonferrous metal mineral resources (Jiang, Li, Evans, Wu, & Cao, ; Li, Sun, et al, ; Li, Palinkaš, Watanabe, & Xi, ; Li, Wu, Evans, Jiang, & Zhou, ; Liu et al, ; Wu, Li, Algeo, Jiang, & Zhou, ). Caledonian movement resulted in metamorphism of Cambrian–Sinian sedimentary rocks and folding and uplift of the basement in South Hunan.…”

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.

Based on field geological investigation and zircon U-Pb isotope dating of granites in Guangzhou, central Guangdong, the formation age, petrogenesis and weathering characteristics of granites are discussed. The LA-ICPMS zircon U-Pb ages of Huolushan and Liuqianshan granites in central Guangdong are 159.1 ± 3.5 Ma and 156.2 ± 4.4 Ma, respectively. These granites show low crystallization temperature (~ 800 °C) and negative low ε Hf (t) values (− 9.4 and − 9.8), with two-stage model ages of 1241-1666 Ma, indicating that they were derived from partial melting of the Proterozoic crust. According to the geological and geomorphological characteristics of the granite area in central Guangdong, it is considered that lithology is the material basis of the granite landscape. Structural factors such as joints and faults are important controlling factors. The climatic and hydrological conditions in the granite area also play an important role in the formation of granite landforms.
