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.

Protolith zircon in high-grade metagranitoids from Queensland, Australia, partially recrystallized during granulite-grade metamorphism. We describe the zircon in detail using integrated cathodoluminescence, U–Pb isotope, trace element and electron backscatter diffraction pattern (EBSP) analyses. Primary igneous oscillatory zoning is partially modified or obliterated in areas within single crystals, but is well preserved in other areas. A variety of secondary internal structures are observed, wit...

The ore deposits of the Mesozoic age in South China can be divided into three groups, each with different metal associations and spatial distributions and each related to major magmatic events. The first event occurred in the Late Triassic (230–210 Ma), the second in the Mid–Late Jurassic (170–150 Ma), and the third in the Early–Mid Cretaceous (120–80 Ma). The Late Triassic magmatic event and associated mineralization is characterized by peraluminous granite-related W–Sn–Nb–Ta mineral deposits. ...

Abstract The Xihuashan complex intrusion in South China, which is emplaced at ca. 154 Ma, mainly comprises medium-grained porphyritic biotite granite, medium-grained biotite granite, and fine-grained two-mica granite. Medium-grained biotite and fine-grained two-mica granites are important tungsten-bearing granites and contain an unusual amount of garnet. Garnets from this intrusion are dominated by almandine and spessartine, which constitute 94% to 99% of the total molecular composition of the g...

Abstract During the Late Mesozoic, extensive magmatism and associated ore deposits were developed in the southeast Hubei Province, Middle–Lower Yangtze River metallogenic belt (MLYRB), East China. To understand the petrogenesis of the intrusions in the area, we performed in situ zircon U–Pb and Hf isotopic analyses on 14 samples from the Fengshangdong stock, and from the Echeng, Tieshan, Wangbaoshan–Jinshandian and Yangxin batholiths. Three major suites of intrusive rocks are recognized in the s...

A finite difference model of the cooling of an igneous intrusive of limited volume is developed and used to investigate the relation between igneous intrusion, the formation of liquid and vapor dominated geothermal systems, and the formation of porphyry-type ore deposits. The model takes into account the properties of pure water and accommodates the phenomena of boiling and condensation. Permeability, level of intrusion, and pluton volume are systematically varied. Pressure, temperature, and flu...

Abstract The Furong deposit, located in southern Hunan Province, China, is a newly-discovered giant tin deposit spatially associated with the A-type Qitianling granite. The petrogenetic link between the giant Furong tin deposit and the Qitianling granite batholith remains controversial because of the lack of precise dating for the tin–polymetallic mineralization. Here we report for the first time in-situ U–Pb data on cassiterite obtained by LA-MC-ICP-MS and the results are compared to ID-TIMS da...

Tin mineralization at Zaaiplaats is hosted in alkali feldspar granites of the Lebowa Granite Suite which intrude the Rashoop Granophyre Suite. From the upper contact downward, the alkali feldspar granites include the marginal pegmatite, fine-grained Lease Granite and the coarse-grained Bobbejaankop Granite. The major mineralization styles consist of subhorizontal, tabular, low-grade orebodies in the Lease Granite, a lower zone of disseminated cassiterite mineralization in the Bobbejaankop Granit...

U-Pb zircon dating by laser ablation requires a reliable matrix-matched external standard to correct for instrumental isotopic fractionation. The most commonly used reference material, the 91500 zircon from Ontario, i s almost exhausted, and GEMOC has searched for a suitable alternative zircon standard for U-Pb dating. G & J Gem Merchants (Sydney) donated a parcel of large zircon fragments (~1cm across), believed to be from E. African pegmatites. These range in colour from red to pinkish-red, ye...

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...

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 ...

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...

The Baotan tin deposit (23 Mt @ 0.43% Sn) is located in the Jiuwandashan–Yuanbaoshan area, South China. It is hosted in Neoproterozoic mafic/metasedimentary rocks and apical portions of the Pinying granite pluton. Six alteration and mineralization stages have been identified: pre-ore alteration, cassiterite greisen, cassiterite–tourmaline–quartz vein, cassiterite–quartz vein, cassiterite–sulfide vein, and post-ore quartz/calcite–quartz vein stages. Tin mineralization is mainly in the cassiterite...
