“…The Shi-Hang zone, well-known as the collision suture between the Yangtze Block and Cathaysia Block in the Neoproterozoic, is also an important granitic magmatic belt and polymetallic metallogenic belt [1][2][3]. As a significant part of the Shi-Hang zone, the W-Sn-Pb-Zn mineralization in this South Hunan possesses an obvious zoning feature from east to west: Shizhuyuan and Yaogangxian W deposits in the eastern part, Furong, Xianghualing and Furong Sn deposits in the middle part, and Huangshaping and Baoshan Pb-Zn plutons related with these large deposits have been drawn the attention of geologists, and abundant geochronological and geochemical data have been reported recently, such as Qitianling pluton (155.5 ± 1.3 Ma, associated with the Furong Sn deposit [13]), Qianlishan pluton (157 ± 2 Ma, associated with the Shizhuyuan W deposit [15]), Yaogangxian pluton (156.9 ± 0.7 Ma, associated with the Yaogangxian W deposit [11]), Huangshaping pluton (154.3 ± 1.9 Ma, associated with the Huangshaping Pb-Zn deposit [16]), and Baoshan pluton (158 ± 2 Ma, associated with the Baoshan Cu-Mo-Pb-Zn deposit [6]). These coeval granitic plutons in South Hunan, related to different metallic mineralization, have been an ideal place to probe into the magmatism and related mineralization of South China.…”

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 regional fault is the NE-trending Chenzhou-Linwu fault which controls the spatial distribution of the granitic intrusions and numerous W-Sn polymetallic deposits associated with the granitic magma activities (Figure 1b; [56,57]). Numerous granitic intrusions were emplaced in this region, most of which are Indosinian and Yanshanian pluton, and these granites are mostly peraluminous, calc-alkaline and remelted granites [12,23,27,28,58,59].…”

Abstract:The recently explored Xitian tungsten-tin (W-Sn) polymetallic ore field, located in Hunan province, South China, is one of the largest ore fields in the Nanling Range (NLR). Two major metallogenic types appeared in this ore field, skarn-and quartz vein-type. They are distributed within Longshang, Heshuxia, Shaiheling, Hejiangkou, Goudalan, and so on. Hydrothermal zircons from two altered granites yielded U-Pb ages of 152.8 ± 1.1 Ma, and 226.0 ± 2.8 Ma, respectively. Two muscovite samples from ore-bearing quartz vein yielded 40 Ar/ 39 Ar plateau ages of 156.6 ± 0.7 Ma, 149.5 ± 0.8 Ma, respectively. Combined with the geological evidence, two metallogenic events are proposed in the Xitian ore field, with skarn-type W-Sn mineralization in Late Triassic (Indosinian) and quartz vein/greisen type W-Sn mineralization in Late Jurassic (Yanshanian). The relatively low Ce/Ce* ratios and high Y/Ho ratios in zircons from two altered granites indicate that the hydrothermal fluids of two metallogenic events are characterized by low oxygen fugacities and enrichment in F. The similar chondrite-normalized patterns between the skarn and Xitian Indosinian granites and Sr-Nd-Pb isotopic compositions of wolframite suggest that the metal sources for both types W-Sn mineralization are derived from a crustal source.

“…The Xianghualing orefield is located in the northern Guangxi southern Hunan A-type granite belt [28,29]. Mineralization-related granitic intrusions in southern Hunan, e.g., the Qianlishan granite in the Shizhuyuan orefield [61] and granites in the Huangshaping deposit [36], formed during 160-150 Ma in a post-orogenic extensional and thinning tectonic environment [28,33]. The magmatic rocks originated from metasomatized Neoproterozoic volcanic-sedimentary materials [29,33] mixed with lithospheric-mantle-derived magmas [28].…”

Abstract:Although numerous W-Sn-Pb-Zn polymetallic deposits are located in southern Hunan, and In-bearing deposits are related to W-Sn-Pb-Zn polymetallic deposits, Indium mineralization in southern Hunan is poorly studied. In order to investigate the In mineralization of the Xianghualing orefield, which is a typical orefield in southern Hunan, ore bulk chemistry, microscopic observation, and electron-probe microanalysis of vein-type (type-I) and porphyry-type (type-II) Sn-Pb-Zn orebodies were studied. The In contents of the type-I orebodies varies from 0.79 to 1680 ppm (avg. 217 ppm, n = 29), and that of the type-II orebodies varies from 10 to 150 ppm (avg. 64 ppm, n = 10). Although chalcopyrite and stannite contain trace amounts of In, sphalerite is the most important In-rich mineral in the orefield. Sphalerite in type-I orebodies contains from <0.02 to 21.96 wt % In, and in type-II orebodies contains from <0.02 to 0.39 wt % In. Indium-rich chemical-zoned sphalerite contains 7 to 8 wt % In in its core and up to 21.96 wt % In in its rim. This sphalerite may be the highest In-bearing variety in Southern China. The Cd contents of the In-rich sphalerite ranges from 0.35 to 0.45 wt %, which places it in the the "Indium window" of the Cu-In-S phases. The geological and structural features of the Xianghualing orefield indicate that the In mineralization of the two types of In-bearing Sn-Pb-Zn orebodies is related to the volatile-rich, In-rich, A-type granites, and is controlled by the normal faults of magmatic-diapiric activity extensional features.
