Abstract
Abstract The world-class Dongpo orefield, located in the Nanling Range, South China, is famous for its large-scale accumulation of W–Sn–Mo–Bi–Pb–Zn–Ag deposits, which includes the giant Shizhuyuan W-Sn-Mo-Bi, Jinchuantang Sn-Bi, Yejiwei Sn-Cu and Congshuban Pb-Zn-Ag deposits. The polymetallic mineralization around the Qianlishan pluton exhibits systematic zoning and comprises proximal W–Sn–Mo–Bi skarn-greisen and distal Pb–Zn–Ag veins. However, the timing and genetic link of its proximal skarn-greisen W–Sn–Mo–Bi and distal vein-type Pb–Zn–Ag mineralization are not well constrained. Here, we present systematic geochronological data to constrain the geochronological framework and genetic model of the giant Dongpo orefield. The muscovite 40 Ar– 39 Ar age of the greisen-type ore in the Shizhuyuan W–Sn–Mo–Bi deposit is 151 ± 1 Ma, which is consistent with the formation of the skarn-type ore and the Qianlishan pluton, thus indicating that they are genetically related and both formed contemporaneously at ∼151 Ma. The large-scale accumulation of W–Sn–Mo–Bi in the Shizhuyuan deposit may have occurred in a short duration of ∼1 Ma. The muscovite 40 Ar– 39 Ar ages (155.5 ± 1.1 and 156.8 ± 1.1 Ma) and molybdenite Re–Os age (153.8 ± 4.2 Ma) of the Ma’naoshan W–Sn–Fe–Mn–Pb–Zn deposit, as well as the zircon U–Pb age (152.7 ± 0.9 Ma) of the Yejiwei Sn–Cu deposit in the Dongpo orefield, are consistent with the age of the Qianlishan pluton, thus indicating that the proximal skarn-greisen W–Sn–Mo–Bi mineralization in the Dongpo orefield is genetically related to the Qianlishan pluton. In addition, the Rb–Sr dating of sphalerite indicates that the vein-type Pb–Zn–Ag mineralization in the Congshuban area formed at 152 ± 2 Ma, which is consistent with the LA–MC–ICP–MS zircon U–Pb age (156–155 Ma) of the equigranular biotite granite, indicating that the distal vein-type Pb–Zn–Ag mineralization is genetically associated with the Qianlishan equigranular biotite granite. By integrating the high-precision geochronological data of this study with those of previous studies, the new genetic model of the large-scale accumulation of W–Sn–Mo–Bi–Pb–Zn–Ag in the Dongpo orefield suggests that the proximal skarn-greisen W–Sn–Mo–Bi and distal vein Pb–Zn–Ag mineralization in the Dongpo orefield are genetically related to the Qianlishan pluton and that the mineralization type is mainly controlled by the characteristics of the wall rock.

The Shizhuyuan polymetallic deposit is located in the central part of the Nanling region, southeastern China, and consists of proximal W–Sn–Mo–Bi skarns and greisens and distal Pb–Zn–Ag veins. The sulfides and sulfosalts in the distal veins formed in three distinct stages: (1) an early stage of pyrite and arsenopyrite, (2) a middle stage of sphalerite and chalcopyrite, and (3) a late stage of galena, Ag-, Sn-, and Bi-bearing sulfides and sulfosalts, and pyrrhotite. Combined sulfide and sulfosalt...

Abstract The Qin–Hang intra-continental porphyry–skarn Cu polymetallic belt (QHMB) is among the economically important metallogenic belts in South China. The significant differences in the size and metal assemblage of the Jurassic magmatic–hydrothermal ore deposits in this belt remain as an enigma. Here we employ zircon U–Pb and Hf–O isotopes of the Tongshanling and Baoshan Cu–Pb–Zn deposits in the central part of the QHMB to investigate the contrasting metallogenic architecture. Our SIMS zircon...

Abstract In South China, the Yangtze and Cathaysia blocks were welded together along the Jiangnan Fold Belt during Neoproterozoic time (∼830 Ma). Large-scale mineralization in these two blocks occurred from Proterozoic to Cenozoic, making the region one of the most important polymetallic metallogenic provinces in the world. Of particular importance are world-class deposits of iron-oxide copper gold (IOCG), sediment-hosted Mn-P-Al-(Ni, Mo, PGE), syenite-carbonatite-related REE, felsic intrusion-r...

Abstract South China hosts the most abundant and largest tungsten (W) deposits in the world, being a famous W metallogenic region. Located at the eastern part of the South China Block, which was formed by amalgamation of the Yangtze and Cathaysia Blocks during the Neoproterozoic, these W deposits were mainly formed during the Mesozoic. The W mineralization is dominanted by greisen, quartz-vein, skarn, and porphyry types, all of which are genetically related to the evolution of highly fractionate...

Abstract The Late Mesozoic Qianlishan granitic complex in the western Nanling Range, South China is associated with the Shizhuyuan giant W–Sn–Mo–Bi polymetallic deposit. It mainly consists of three phases of intrusions, P-1 porphyritic biotite granite, P-2 equigranular biotite granite and P-3 granite porphyry. All three phases of granite contain quartz, plagioclase, K-feldspar and Fe-rich biotite. They have geochemical affinities of A-type granites, e.g., high FeO T /(FeO T + MgO) ratios (0.84–0...

The Qianlishan is a well-known granitic pluton directly related to the super large W-Sn-Mo-Bi polymetallic Shizhuyuan deposit in southeast China. The pluton is composed of three intrusive phases: the first phase of microfine-grained porphyritic biotite granite, the second phase of fine-grained porphyritic biotite granite, and the third phase of medium-grained equigranular zinnwaldite granite. SIMS zircon U-Pb dating yields precise ages for three phases; they are 154.5 and 152.3 Ma, 153.4 and 152...

Abstract The Jiepailing deposit, located in southern Hunan Province, China, is a giant Sn–Be–F deposit in the Nanling W–Sn province. The Sn–Be–F mineralization is spatially associated with the Jiepailing granite porphyry. LA-MC-ICP-MS zircon U–Pb dating of the Jiepailing granite porphyry yielded a weighted mean 206 Pb/ 238 U age of 90.5 ± 0.9 Ma (MSWD = 0.32), which is interpreted as the emplacement age of the granite porphyry. Hydrothermal muscovite yields a plateau 40 Ar/ 39 Ar age of 92.1 ± 0...

Abstract The Yangtze Block has a Paleoproterozoic and Archean basement and was traditionally thought to have been cratonized after the Neoproterozoic. Recent studies reveal that the southwestern part is remarkably different from other parts of the block. Major Fe–Cu deposits are present in the southwestern part where they form the Kangdian IOCG metallogenic province in southern China and northern Vietnam. Large Fe–Cu deposits include Lala and Xikuangshan to the north, Yinachang in the center, Da...

Abstract Many composite granite plutons occur in South China, accompanied by large-scale polymetallic mineralization. Each composite pluton is composed of main-phase granite and late-stage highly differentiated granite. Traditionally, the highly differentiated granite is thought to be residual melt of the former via fractionation, and ore-forming materials and fluids are from granite magma itself. We propose a different model for the origin of the granites and related mineralization, based on pe...

Abstract The giant Shizhuyuan W–Sn–Mo–Bi–Pb–Zn polymetallic skarn-type deposit, which lies in the world-famous Nanling W–Sn metallogenic belt, has a close affinity with the Qianlishan granite complex. Previous studies focused on the Qianlishan granitoids rather than relevant skarns, where the evolutionary processes of skarn-forming fluids, mineralized fluids and sources of metals are debated. This study carried out systematic EPMA and LA-ICPMS zircon U–Pb dating, major- and trace-element and Lu–...

Abstract The Pingtan deposit in southwestern Hunan Province is a newly-discovered, large-sized W-(Mo) deposit. This deposit is situated in the northwestern part of the Miao’ershan granite batholith, western Nanling Range. The tungsten mineralization is mainly hosted in biotite monzogranite, and the alteration related to mineralization is controlled by a NE-trending fault zone. In this paper, we present new molybdenite Re–Os and zircon U–Pb ages, zircon Lu–Hf isotope and REE geochemical data, aim...

Abstract The Xihuashan tungsten ore deposit in the central Nanling region, South China is a vein-type hydrothermal deposit associated with the Late Jurassic granitoids that were previously thought to be the products of crustal anatexis alone. In this study, we use helium (He) and argon (Ar) isotopes of fluid inclusions entrapped in pyrite and arsenopyrite to determine the origin of the ore-forming fluids. The 3 He/ 4 He ratios of the crushed fluid inclusions vary from 0.15 to 1.16 Ra, with a mea...

Hydrogen peroxide (H2O2) is a strong oxidizer that causes non-selective oxidation of sulfide minerals, and its influence on bismuth sulfide ores is not well-documented. In this study, H2O2 was proposed as an alternative bismuthinite depressant, and its effect on a Mo-Bi-containing ore was intensively investigated by batch flotation tests. Results showed that the addition of H2O2 significantly destabilized the froth phase, thus decreasing the solids and water recovery. The recovery of bismuth in ...
