“…As a part of Jurassic tectonic-magmatic activity in South China, the Laiziling and Jianfengling plutons might be formed in the same tectonic setting with other coeval granitic plutons, such as Qitianling, Guposhan, and Jiuyishan plutons [62,93,94]. However, the geodynamic mechanism triggering the extensional setting and magma activity in South China has long been in debate for decades [59,[97][98][99][100][101][102][103][104][105][106][107]. Several models have been proposed to illustrate the geodynamic mechanism, for example, westward subduction of the paleo-pacific plate, mantle plume, post-collision, and so on [97][98][99][100][101]104,105,107].…”

Two small-sized granitic plutons, outcropped in Xianghualing ore field, South Hunan (South China), have a close relationship with the super large-scale Sn-W polymetallic mineralization in this ore field. The Laiziling and Jianfengling plutons are composed of medium-to coarse-grained two-mica and coarse-grained biotite granites, respectively, and have zircon U-Pb ages of 156.4 ± 1.4 Ma and 165.2 ± 1.4 Ma, respectively. Both of the Laiziling and Jianfengling granites are characterized by extremely similar elemental and Lu-Hf isotopic compositions with high contents of SiO 2 , Al 2 O 3 , Na 2 O, K 2 O, high A/CNK ratios, negative ε Hf (t) values (ranging from −3.86 to −1.38 and from −5.44 to −3.71, respectively), and old T DMC ages (ranging from 1.30 to 1.47 Ga and from 1.32 to 1.56 Ga, respectively). These features indicate that they both belong to highly fractionated A-type granites, and were formed in an extensional setting and from the same magma chamber originated from the Paleoproterozoic metamorphic basement of South China with a certain amount of mantle-derived magma involved with temperatures of ca. 730 • C and low oxygen fugacity.

“…The most common primary sources of W are skarn and stockwork deposits related to peraluminous granites [3]. These can occur in a variety of geodynamic settings related to plates convergence, i.e., anorogenic magmatism, cordillera-type arc environments (porphyry setting), and mostly collisional setting either during onset or collapsing stages [4][5][6][7]. Although it is recognised that wolframite mineralization in stockwork is commonly associated to greisen alteration ("an assemblage of quartz plus muscovite, accompanied by varying amounts of other distinctive minerals such as fluorite, topaz and tourmaline" [8]) in underlying granites, the genetic link between wolframite mineralization and greisen fluids is still being discussed by some authors [9][10][11][12][13], in particular because wolframite is only rarely observed within the greisen itself (e.g., in the Erzgebirge [14]).…”

“…Indeed, Lecumberri-Sanchez et al [15] highlight that Fe and Mn, necessary for effective wolframite crystallization, mostly originate from the schist host rock, which would explain the fact that wolframite is commonly restricted to quartz veins located in the host rock. Nevertheless, numbers of recent studies, particularly on Asian W mineralizations, have underlined the role of greisen and propose that W, as other high field-strength elements (e.g., Nb, Ta, Sn), derive in part or totally from greisen fluids [6,[16][17][18][19]. Their greisen-related model is similar to that proposed for W deposit in Cornwall [20][21][22], where wolframite-bearing quartz veins and greisen alteration are linked by the occurrence of well-developed greisen alteration in the selvages of the mineralized veins, as well as by similar characteristics of fluid inclusions in the veins and in the greisen alteration.…”

Multiple Generations of Wolframite Mineralization in the Echassieres District (Massif Central, France)

et al. 2019

The Echassières district in central France contains complex rare-element ore deposits, whose formation is related to exotic igneous events and several hydrothermal episodes that are not entirely understood to date. Tungsten mineralization consists of three generations of wolframite, characterized by distinct Fe/Mn ratios (8.4; 3.5 and 0.3, for wolframite a, b and c, respectively), formed during three separate hydrothermal episodes related to the Variscan orogeny. Wolframite a occurs in quartz veins of the La Bosse stockwork where it crystallized before the Barrovian metamorphism that affected these veins and the host rock. After metamorphism, before intrusion of the Beauvoir and Colettes granites, wolframite b crystallized in the stockwork during massive topazification. High concentrations of wolframite c occur in the proximal quartz veins in the Mazet area, while only scant amounts are found in the La Bosse stockwork. In both settings, wolframite c precipitated from the fluid responsible for greisen alteration that massively affected the Beauvoir granite. In the La Bosse stockwork, greisen alteration is characterized by hydrothermal topaz that is texturally and chemically distinct from that precipitated during topazification. Supergene alteration responsible for kaolinization of Beauvoir and Colettes granites caused remobilization of a non-negligible amount of tungsten (W) during replacement of wolframite by W-rich goethite in all units of the Echassières district. This model for multiple W mineralizing events is novel and can prove essential in distinguishing potential economic deposits worldwide.

“…The Mesozoic is a critical period for large-scale W-Sn polymetallic mineralization in South China. The accurate dating of ore minerals and ore-related granites indicates that there are three stages (~230-210, 170-150, and 120-80 Ma) of granite magmatism and metallogenic events in South China during the Mesozoic (Mao et al, 2013;Pirajno, 2013a;Zhao et al, 2017).…”

U–Pb geochronology and Raman spectroscopy of zircons from the granites in the Xihuashan and Tieshanlong Deposit: Implications for W‐Sn mineralization in Southern Jiangxi Province, South China

et al. 2019

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.
