Abstract
The Lianhuashan deposit has long been regarded as a typical tungsten porphyry deposit, located in the eastern Guangdong Province, in the Southeastern Coastal Metallogenic Belt (SCMB). LA–MC–ICP–MS zircon U–Pb dating of the quartz porphyry yielded a weighted mean 206Pb/238U age of 137.3 ± 2.0 Ma, which is interpreted as the emplacement age of the quartz porphyry. Hydrothermal muscovite yielded a plateau 40Ar/39Ar age of 133.2 ± 0.9 Ma, which is consistent with the zircon U–Pb age, suggesting that the tungsten mineralization is genetically related to the quartz porphyry. Combined with previous studies, we suggest that there is a 145–135 Ma episode linking the granitic magmas with W–Sn ore systems in the SCMB. Zircon eHf (t) values of the quartz porphyry are in range of − 3.8 to 0.9, and the two-stage Hf model ages (TDM2) are 1.1–1.4 Ga, which is younger than the basement rocks in the Cathaysia Block (1.8–2.2 Ga), signifying that the quartz porphyry was predominantly derived from melting of Mesoproterozoic crust containing variable amounts of mantle components. In combination with the newly recognized coeval alkaline/bimodal magmatism and A-type granites in eastern Guangdong, we suggest that the 145–135 Ma W–Sn metallogenic event of the SCMB is related to a geodynamic setting of large-scale lithospheric extension and thinning, which can be ascribed to melting of the crust caused by mantle upwelling, triggered by the oblique subduction of the Izanagi plate.

Abstract The Taoxihu deposit (eastern Guangdong, SE China) is a newly discovered Sn polymetallic deposit. Zircon U-Pb dating yielded 141.8 ± 1.0 Ma for the Sn-bearing granite porphyry and 145.5 ± 1.6 Ma for the biotite granite batholith it intruded. The age of the granite porphyry is consistent (within error) with the molybdenite Re–Os isochron age (139.0 ± 1.1 Ma) of the Sn mineralization, indicating a temporal link between the two. Geochemical data show that the granite porphyry is weakly pera...

Abstract The recently discovered Jinkeng deposit, located in eastern Guangdong Province, SE China, is a granite-related cassiterite–sulfide-type Sn–Cu–Pb–Zn deposit in the Cathaysia Block. Zircon U–Pb dating of the biotite granite and fine-grained granite associated with the deposit yielded concordant ages of 144.7 ± 0.8 Ma and 141.1 ± 1.3 Ma, respectively. These ages are consistent, within error, with the molybdenite Re–Os isochron age of 139.3 ± 2.5 Ma for the deposit, indicating a temporal li...

Abstract The Xishan deposit, located in the western Guangdong Province in South China, is a quartz-vein type W-Sn deposit with an average Sn grade of 0.1–0.4 wt%. The deposit is temporally and spatially associated with Xishan alkali feldspar granite. The W–Sn mineralization is present mainly as veins that are hosted by the granite. In this paper we present new zircon U–Pb age, whole-rock geochemical data, Sr–Nd–Pb–Hf isotopic data and Re–Os age in order to constrain the nature and timing of magm...

Abstract The Feie'shan W-Sn deposit is in eastern Guangdong Province, which is a newly explored deposit in the southeastern coastal metallogenic belt. In order to constrain the age of mineralization in the Feie'shan W-Sn deposit, we collected molybdenites and hydrothermal biotite of the Feie'shan W-Sn deposit for dating. The tungsten mineralization is spatially associated with the biotite monzonitic granite porphyry. LA-MC-ICP-MS zircon U-Pb dating of the biotite monzonitic granite porphyry yiel...

Major and trace elements, whole rock Sr–Nd–Pb isotopes, LA–ICP–MS U–Pb zircon dating, zircon trace elements and Hf isotope data are reported for a suite of A-type granites from Yingwuling pluton in western Guangdong province, South China. Zircon U–Pb ages obtained by laser ablation–inductively coupled plasma–mass spectrometry (LA–ICP–MS) show that biotite granite and alkali feldspar granite were emplaced in 81.3 ± 0.6 Ma and 80.6 ± 0.5 Ma, respectively. Both of the two suites have the petrograph...

Abstract Zijinshan is the largest high-sulfidation epithermal Cu–Au deposit on mainland China. The primary mineralization at the deposit is characterized by pyrite, digenite and covellite. Although some Rb Sr isochron ages of the fluid inclusions in quartz and the apparent K-Ar age of the Cu-bearing alunite alteration zone have been previously interpreted as the ore-forming age, the Rb-Sr and K-Ar dating systems are usually readily reset due to their closure temperature, and thus document the la...

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...

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 Feie'shan greisen–type W–Sn deposit in the eastern Guangdong Province forms part of the Southeastern Coastal Metallogenic Belt (SCMB) in South China. Here we present zircon LA–ICP–MS U–Pb geochronology of the biotite granite which shows a weighted mean 206 Pb/ 238 U age of 134.7 ± 2.0 Ma, consistent with the zircon U–Pb, biotite 40 Ar– 39 Ar and molybdenite Re–Os ages in the previous study. The biotite granite is peraluminous and belongs to high–K calc–alkaline type. It is character...
