Abstract
Abstract Numerous Late Cretaceous W–Sn deposits associated with granitic rocks were developed in the southern part of South China. However, the relationship among granitic magma, mineralization and tectonic setting remains disputed. The Yingwuling W–Sn deposit is spatially associated with K-feldspar granite and biotite granite in the southwestern part of Guangdong province, South China. LA-ICP-MS zircon U–Pb dating of K-feldspar granite, biotite granite and weathered ore-bearing granites yielded ages of ∼79 Ma, which agree well with the LA-ICP-MS cassiterite U–Pb age of 79.6 ± 0.9 Ma, indicating a close genetic link between the Yingwuling pluton and W–Sn mineralization. Geochemically, both K-feldspar granite and biotite granite show high SiO 2 , Na 2 O + K 2 O and low CaO, P 2 O 5 contents, and they belong to shoshonitic series and high-K calc-alkaline series, respectively. High Rb/Sr ratios and low Nb/Ta and Zr/Hf ratios of the Yingwuling pluton indicate strong magmatic differentiation. Compared with K-feldspar granite, biotite granite experienced a higher degree of fractional crystallization as indicated by lower Fe 2 O 3 , TiO 2 , LREE, Sr, Eu, Ba and Zr contents and higher SiO 2 , HREE, Rb, Cs and Y contents. Their Sr and Nd isotope compositions (initial 87 Sr/ 86 Sr = 0.7027 and 0.7097; e Nd (t) = −5.6 and −5.7) are less radiogenic than that of the South China basement. Thus, it is likely that some juvenile materials were involved in the formation of these granitic intrusions. This is also favored by the wide range of zircon Hf isotope values (e Hf (t) = −6.6 to 0.8), which indicates mixing processes. A-type granite affinity of the Yingwuling pluton shows that it was possibly formed in an extensional setting. Late Cretaceous W–Sn deposits constitute an EW-trending belt from Guangdong to Yunnan provinces, which was compatible with the northward subduction of the Neo-Tethys plate rather than the northwestward subduction of the Pacific plate during Late Cretaceous. Combined with previous studies on magmatic rocks and tectonic activities during Late Cretaceous in South China, this study suggests that the subduction of the Neo-Tethys plate was most possibly responsible for the Late Cretaceous Yingwuling granitic intrusion and associated W–Sn mineralization.

Abstract The Gaosong Sn–Cu deposit in the Gejiu ore district, SW China, is a large cassiterite–sulfide deposit, hosting total ore reserves of 67.4 Mt @1.3% Sn and 19.0 Mt @1.1% Cu. Two types of mineralization developed in the deposit, i.e. cassiterite-sulfide ore within the proximal skarn in contact with the Gaofengshan biotite granite, and fault-controlled stratiform-like cassiterite–iron oxide ± sulfide ore in the distal carbonate country rock. Cassiterite grains are disseminated in both ores....

Abstract The Xishan Sn–W deposit is spatially related to K-feldspar granites in the Yangchun basin, western Guangdong Province, South China. LA-ICP-MS zircon U–Pb dating for the Xishan pluton defines an emplacement age of ~ 79 Ma (78.1 ± 0.9 Ma; 79.0 ± 1.2 Ma; 79.3 ± 0.8 Ma), consistent with the mineralization age of the Xishan Sn–W deposit constrained by molybdenite Re–Os isochron age (79.4 ± 4.5 Ma) and LA-ICP-MS cassiterite U–Pb ages (78.1 ± 0.9 Ma and 79.0 ± 1.2 Ma) for the cassiterite-quart...

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...

Granite is one of the most important components of the continental crust on our Earth; it thus has been an enduring studied subject in geology. According to present knowledge, granite shows a great deal of heterogeneity in terms of its texture, structure, mineral species and geochemical compositions at different scales from small dike to large batholith. However, the reasons for these variations are not well understood although numerous interpretations have been proposed. The key point of this d...

Abstract Oxygen fugacity ( f O 2 ) is a key factor that controls the formation of porphyry Cu deposits. Porphyry Cu deposits are typically oxidized, but when and how porphyry magmas gain their high oxygen fugacity signatures, and how oxygen fugacity controls porphyry mineralization, remains obscure. To trace the origin of the high oxygen fugacity in porphyry Cu deposits, we determined trace element compositions and U-Pb ages of magmatic and inherited zircon from Dexing porphyry Cu deposit, calcu...

Abstract The Shanhu orefield, located in the northeastern Guangxi province, is an important part of W-Sn polymetallic metallogeny in the Nanling region. The Shanhu W-Sn deposit is spatially associated with the Yantianling granite. LA-ICPMS zircon U-Pb dating of the Yantianling granite yields Late Cretaceous ages of 100.9 ± 2.2 Ma and 100.8 ± 2.3 Ma. Hydrothermal muscovite 40 Ar/ 39 Ar dating yields plateau ages of 102.7 ± 1.7 Ma and 100.8 ± 0.7 Ma. This date coincides well with the LA-ICPMS zirc...

Abstract Large scale Cretaceous magmatism and SnCu mineralization occurred in an E-W-trending ore belt from southwest China to western Myanmar. We investigated the genesis of the world-class Dachang Sn-polymetallic and newly discovered Baoshan Cu deposit in Guangxi Province, southwest China, and the tectonic setting of this belt. The Dachang ore field contains a giant vein ore body (No.100) and stratiform ore bodies (No. 91 and 92). The cassiterite U-Pb age (92.5 ± 4.4 Ma) of the No. 100 ore bod...

The Yanshan Movement occurred mainly during the Middle-Late Jurassic, and gave rise to NE trending structures, magmatic events, volcanism and mineral resources. The transformation and evolution of the movement during the Middle-Late Jurassic were investigated from the rock assemblage, geochemistry, and chronology in adamellites which were exposed in the Xingcheng area, western Liaoning. Two types of adamellites were recognized—biotite adamellites with the formation age of 172–168 Ma and garnet-b...

Plate subduction is the largest natural factory that processes elements, which controls recycling and mineralization of a variety of elements. There are three major ore deposit belts in the world: the circum-Pacific, the central Asian, and the Tethys belts. All the three belts are closely associated with plate subductions, the mechanism remains obscure. We approached this problem from systematic studies on the behaviours of elements during geologic processes. This contribution summaries the rece...
