“…As mentioned above, proximal W-Mo mineralization has close spatial and temporal relationships with granite porphyry rather than with quartz porphyry and felsite (e.g. Ma et al 2007;Yao et al 2007;Lei et al 2010;Qi et al 2012;Ding et al 2018a, b;Zhu et al 2021), suggesting that granite porphyry might be one of the sulphur sources for W −Mo mineralization in the Huangshaping deposit.…”

The Huangshaping deposit is unique in southern Hunan Province, China, as it hosts economic reserves of both W–Mo and Pb–Zn mineralization, which are usually associated with granite and granodiorite porphyry in this area, respectively. This study reports results of in situ LA-MC-ICP-MS sulphur isotopic composition analyses conducted on sulphides from both W–Mo and Pb–Zn mineralization from the Huangshaping deposit with the aim of constraining ore genesis for this deposit. All samples from the proximal W–Mo mineralization have relatively uniform and high δ34S values (8.7 ‰ to 16.0 ‰), close to the range for carbonate sediments in this deposit (13.8 ‰ to 18.1 ‰). These patterns suggest that the granite porphyry in this deposit was the sulphur source for W–Mo mineralization, and that the assimilation of evaporite from the carbonate sediments led to the high δ34S values of the granite porphyry. Sulphides from the Pb–Zn mineralization have δ34S values (2.2 ‰ to 10.3 ‰) lower than those of the W–Mo mineralization, and generally increase in this paragenetic order, with the lowest δ34S values being similar to those of the basement (3.8 ‰ to 7.7 ‰). These patterns indicate that the original sulphur for the Pb–Zn mineralization was most likely derived from the basement, with input of sulphur from the carbonate sediments increasing during the evolution of ore-forming fluids. On the basis of the measured sulphur isotopic compositions, it is suggested that the ore-forming materials for the W–Mo mineralization were derived from the granite porphyry, whereas ore-forming materials extracted from the basement dominated the Pb–Zn mineralization.

“…During the Jurassic, a large-scale lithospheric extension resulted in granitic magmatism and intrusion, and the accumulation of ore-forming materials finally contributed to mineralization in the QHMB [39][40][41][42]. The mineralization is represented by Cu polymetallic deposits (e.g., Tongshanling, Dexing, and Baoshan) [8,12,17,[21][22][23], W (Sn) polymetallic deposits (e.g., Xianghualing and Shizhuyuan) [12,[18][19][20][24][25][26]43], and Cu and W (Sn) polymetallic deposits (e.g., Huangshaping) [27][28][29][30][31][32], which are porphyry-, skarn-, and hydrothermal-type deposits. The contemporaneous granitoids generally have weakly peraluminous and high-K calc-alkaline compositions, except for the high-Mg characteristics of granodiorite porphyry in Dexing [8,12,17].…”

“…Typical examples of the I-type granitoids include the granodiorite porphyry in the Baoshan Cu polymetallic deposit [17][18][19][20] and the granodiorite in the Tongshanling Cu polymetallic deposit [8,12,[21][22][23], while the A-type granitoids are represented by alkali-feldspar granites in the Xianghualing Sn (W) polymetallic deposit [18][19][20] and biotite granites in the Shizhuyuan W (Sn) polymetallic deposit [12,[24][25][26]. In addition, Aand I-type granitoids can be present within a single deposit and are related to different mineralization types, such as granite porphyry and quartz porphyry in the Huangshaping Cu-Sn-W deposit [27][28][29][30][31][32]. Therefore, the ore-forming granites of the Cu and W deposits in the QHMB have different geochemical characteristics, such as differentiation index formation temperature, and oxygen fugacity.…”

Geochronology, Whole-Rock Geochemistry, and Sr–Nd–Hf Isotopes of Granitoids in the Tongshanling Ore Field, South China: Insights into Cu and W Metallogenic Specificity

The Qin-Hang Metallogenic Belt (QHMB), an important metallogenic belt in South China, hosts Cu and W–Sn polymetallic deposits. The Tongshanling ore field in the QHMB is characterized by the coexistence of Cu- and W-bearing polymetallic deposits, which are related to granodiorite and granite porphyry. This study examined whole-rock geochemistry, geochronology, and Sr–Nd–Hf isotopes to determine the genetic relationship between diverse ore-related granitoids (i.e., granodiorite and granite porphyry) and Cu–W metallogeny in the Tongshanling ore field. Zircon LA-ICP-MS U–Pb dating shows that the granodiorite and granite porphyry in the Tongshanling ore field were emplaced at 163.7 ± 0.4 Ma to 154.7 ± 0.6 Ma and 161.1 ± 0.3 Ma, respectively. Geochemically, the granodiorites are classified as oxidized I-type, while the highly evolved granite porphyry is reduced A-type. The Lu–Hf isotopic composition of the granodiorites is characterized by εHf(t) values ranging from –10.49 to –4.99 (average = –7.17), with corresponding TDMC ages ranging from 1524 to 1877 Ma (average = 1682 Ma). In contrast, the granite porphyry has higher εHf(t) values (–3.60 to –1.58, average = –2.78) and younger TDMC (1310–1438 Ma, average = 1387 Ma). The εNd(t) values of granodiorite are −8.06 to −7.37 and the two-stage model ages (TDM2) are 1543–1598 Ma, while the granite porphyry has higher εNd(t) values (−3.0 to −3.4) and younger TDM2 ages (1195–1223 Ma). The results show that the granodiorite and granite porphyry were formed from partial melting of different Mesoproterozoic basement rocks under varying degrees of crust–mantle interaction. Granite porphyry underwent well-recorded fractional crystallization. Compared to the Cu-forming granodiorite, the W-forming granite porphyry has a higher differentiation index, higher crystallization temperatures of zircon (average = 708 °C versus 631 °C), and lower oxygen fugacity (median ΔFMQ = –2.21 versus –1.77).

“…In the natural hydrothermal system, REE concentrations are usually low in hydrothermal fluids [55][56][57]. Precipitation of scheelite results in a strong REE fraction, and the REE patterns of scheelite are highly sensitive to the dynamics of the hydrothermal system [14,58]. Therefore, MREEs in the early ore-forming fluid are incorporated into scheelite and the precipitation of MREEs-rich scheelite significantly alters the composition of the hydrothermal fluid and produce a MREEs-depleted fluid, which results in the subsequent formation of REE-flat even MREE-impoverish scheelite.…”

In situ analyses of trace elements and rare-earth elements (REEs) were performed by use of laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS) on scheelite samples from the Yingzuihongshan tungsten deposit in western Inner Mongolia Autonomous Region, China. The contents of trace elements Nb, Ta and Mo of scheelite indicate that the ore-forming fluid is magmatic hydrotherm and is exsolved from highly fractionated granitic melt. The scheelite has high REE contents and ∑REE values, and a very inhomogeneous distribution of REEs exists in different scheelite grains or even in one scheelite grain. The cathodoluminescence (CL) images of scheelite grains display well-developed zoning or fine oscillatory zoning. Development of zoning is closely related to the variable contents of REEs, and the darkness of shade of CL images are mainly determined by ∑REE values, but they have no correlation with the distribution patterns of REEs. The chondrite-normalized REE distribution patterns of scheelite are classified as the middle REEs (MREEs)-enriched type, except for a strong negative Eu-anomaly, which could be a REE-flat type and or a MREEs-depleted type. Trace element composition of scheelites from the Yinzuihongshan tungsten deposit reflect that the ore-forming materials mainly came from the crust and the ore-forming fluids are dominantly derived from the granitic magma in an oxidizing environment, in which very dynamic conditions of the hydrothermal system prevailed during precipitation of scheelite. On the basis of the above understanding and field geological featured, we considered that the Yingzuihongshan tungsten deposit is the quartz-vein-hosted tungsten type that is genetically associated with monzonitic granite.
