“…The Songligou gold‐telluride deposit formed at 126.6 ± 2.3 Ma, which is consistent with the intensive gold mineralization age of 135–118 Ma in the Xiaoqinling‐Xiong'ershan (Wang et al, ; Wang, Mao, Lu, & Ye, ; Han et al, ; Li et al, 2012b,c; Ren, ; Qiang, Bi, Deng, Guo, & Li, ; Tang et al, ; Tang, ; Zhai, Ye, Zhou, Meng, & Gao, ; Tian et al, ; Zhang et al, ) and 123–115 Ma in the Jiaodong districts (Li, Santosh, & Li, and its references). Thus, the Songligou gold‐telluride deposit, as a part of the Early Cretaceous large‐scale gold mineralization in east NCC, formed in an extensional tectonic setting (Liu et al, ).…”

The Songligou gold‐telluride deposit, located in Songxian County, western Henan Province, China, is one of many gold‐telluride deposits in the Xiaoqinling‐Xiong'ershan district. Gold orebodies occur within the Taihua Supergroup and are controlled by the WNW F101 Fault, and the fault was cut across by a granite porphyry dike. Common minerals in gold orebodies include quartz, chlorite, epidote, K‐feldspar, calcite, fluorite, sericite, phlogopite, bastnasite, pyrite, galena, chalcopyrite, sphalerite, tellurides, gold, bismuthinite, magnetite, and hematite, and pyrite is the dominant sulfide. Four mineralization stages are recognized, including pyrite‐quartz stage (I), quartz‐pyrite stage (II), gold‐telluride stage (III), and quartz‐calcite stage (IV). This work reports the Rb–Sr age of gold‐telluride‐bearing pyrite and zircon U–Pb age of granite porphyry, as well as S isotope data of pyrite and galena. The pyrite Rb–Sr isochron age is 126.6 ± 2.3 Ma (MSWD = 1.8), and the average zircon U–Pb age of granite porphyry is 166.8 ± 4.1 Ma (MSWD = 4.9). (87Sr/86Sr) i values of pyrite and δ34S values of sulfides vary from 0.7104 to 0.7105 and −11.84 to 0.28‰, respectively. The obtained Rb–Sr isochron age represents the ore formation age of the Songligou gold‐telluride deposit, which is much younger than the zircon U–Pb age of the granite porphyry. Strontium and S isotopes, together with the presence of bastnaesite, suggest that the ore‐forming fluid was derived from felsic magmas with input of a mantle component and subsequently interacted with the Taihua Supergroup. Tellurium was derived from metasomatized mantle and was related to the subduction of the Shangdan oceanic crust and Izanagi plate beneath the North China Craton (NCC). This deposit is a part of the Early Cretaceous large‐scale gold mineralization in east NCC and formed in an extensional tectonic setting.

“…The Huaxiong Block is a representative mineral district in EQMB that hosts various types of deposits, especially those related to the regional Mesozoic magmatic-hydrothermal activities, for example, porphyry-skarn Mo-W, epithermal Au, and orogenic Ag-Pb-Zn-Au deposits Chen, Pirajno, Qi, Li, & Wang, 2006;Chen, Ye, & Wang, 2014;Fan, Hu, Wilde, Yang, & Jin, 2011;Han et al, 2013;Han, Yao, Chen, Deng, & Ding, 2014;Mao et al, 2010). The ore genesis, sources of ore-forming fluid and material, and tectonic evolution of the metallic deposits have been well documented by previous studies (Chen et al, 2006;Chen, Pirajno, Li, Guo, & Lai, 2009;Han, Zhang, Pirajno, Wang, & Zhang, 2009;Li, Carranza, Ni, & Guo, 2012;Li, Chen, Pirajno, & Ni, 2013;Tang et al, 2013;Tian et al, 2017;Zhang, Ye, Zhou, & Meng, 2014). Over the past decades, fluorite occurs only as a gangue mineral in these ore deposits (Deng, Gong, Wang, Carranza, & Santosh, 2014;Zhang et al, 2014), yet in recent years, many economic fluorite deposits have been discovered in the Heyu district (north-eastern part of the Huaxiong Block).…”

“…The age and fluid characteristics of the Madiu fluorite deposit imply that the fluorite was deposited at the late stage of the Early Cretaceous mineralization event. The regional Early Cretaceous Mo, Au, and fluorite mineralization were probably related to the large‐scale extension or lithospheric thinning in Eastern China (Mao et al, , , 2011; Tian et al, ).…”

“…Late Mesozoic granitic batholiths and stocks are widespread in the Xiong'ershan–Waifangshan area. For instance, the Wuzhangshan batholith (157 Ma; Mao et al, ), Huashan granite batholith (142.2–131.0 Ma; Li, ; Mao et al, ), and Heyu granite batholith (150–133 Ma; Zhou, ; Gao, Zhang, et al, ; Li et al, ; Zhu, Chen, Liu, & Siebel, ; Bao et al, ) intruded into the Precambrian Taihua and Xiong'er groups and are interpreted as the products of Late Jurassic to Early Cretaceous large‐scale extension or lithospheric thinning of the North China Craton (Mao et al, , ; Mao et al, ; Tian et al, ; Zhang et al, ). The regional Mo–W, Pb–Zn–Ag, and Au mineralization are spatio‐temporal related with granitic intrusions and are associated with the Early Cretaceous tectono‐magmatic event (Deng, Chen, et al, ; Mao et al, ).…”

“…The Machaoying Fault is interpreted as a subduction zone, which formed during the Mesozoic intracontinental collision between the Yangtze and North China cratons and experienced multiple stages of movement (Cao et al, 2015;Chen & Fu, 1992;Hu, 1988;Zhang, Zhang, Han, & Zhang, 2006). The Machaoying Fault is over 200 km and dips 50°-70°to NNE and was reactivated in the Early Cretaceous (Han et al, 2009;Yan, Pang, Yue, & Zhang, 2005;Zhang, Zhang, Han, & Zhang, 2006 Zhou, 2008;Gao, Zhang, et al, 2010;Li et al, 2013;Zhu, Chen, Liu, & Siebel, 2013;Bao et al, 2014) intruded into the Precambrian Taihua and Xiong'er groups and are interpreted as the products of Late Jurassic to Early Cretaceous large-scale extension or lithospheric thinning of the North China Craton (Mao et al, 2002(Mao et al, , 2010Mao et al, 2011;Tian et al, 2017;Zhang et al, 2018).

The Heyu fluorite ore district is newly discovered in the East Qinling metallogenic belt (EQMB), central China. In this district, the large Madiu fluorite deposit contains five Mesozoic granite‐hosted orebodies. The deposit may have formed at shallow depth and occurred as continuous veins controlled by a series of N‐S‐ or NE‐trending, steeply dipping faults. The fluorite mineralization can be divided into two stages (I and II). Fluid inclusions in stage I fluorite homogenized at 132.2°C to 342.5°C (peak at 170°C–210°C) with salinities of 0.18 to 4.43 wt% NaCl equiv, whilst those in stage II fluorite homogenized at 122.2°C to 305.7°C (peak at 130°C–170°C) and salinities of 0.18 to 3.71 wt% NaCl equiv. Raman spectroscopic analysis of the fluid inclusions reveals that they comprise predominantly H2O. The rare earth element (REE) characteristics indicate that the deposit is of hydrothermal origin. The δ18OH2O (−8.8‰ to −0.5‰) and δDH2O (−69.0‰ to −61.9‰) values show a subhorizontal trend, suggesting that the oxygen isotopic compositions were modified by fluid–rock interactions. Fluid inclusion and stable isotopic data suggest that the ore‐forming fluids belong to a meteoric water‐sourced, medium–low temperature, and low salinity NaCl–H2O system. Initial fluorite 87Sr/86Sr ratios (0.708879–0.709682) resemble those of the Heyu batholith. The water–rock reaction, which leached Ca from the host rock and increased the fluid pH, was likely causative to the ore precipitation. Geochemical and mineralization features suggest that the Madiu fluorite deposit is best classified as a fault‐controlled hydrothermal vein‐type fluorite deposit. The Sm–Nd isochron age of 118.9 ± 7.8 Ma and its regional age correlation suggest that the fluorite mineralization occurred under regional extension or lithospheric thinning setting and that the fluorite mineralization was an important component of the Early Cretaceous mineralization event in the EQMB.

Triassic alkaline magmatism and mineralization in the Xiong'ershan area, East Qinling, China

et al. 2018

View full text Add to dashboard Cite

The Qinling orogenic belt is a complex subduction-accretion-collision orogen that welded the North China Craton and the Yangtze Craton during the final continental collision in the Triassic. The Xiong'ershan area, located in east Qinling, exposes a typical Triassic syenite pluton and several contemporaneous Mo, Au, and Cu deposits. The aegirine-augite syenites and syenites from the Mogou pluton are characterized by alkalic to peralkalic (total alkali Na 2 O + K 2 O = 13.95-14.63 wt.%, CaO = 0.06-2.87 wt.%), and shoshonitic features (K 2 O = 11.86-14.34 wt.%). Zircon LA-ICP-MS U-Pb dating of the aegirine-augite syenite and syenite yield emplacement ages of 232.5 ± 0.6 and 221.8 ± 0.7 Ma, indicating multiple pulses of magmatism. Evidence from zircon Hf isotopes; occurrence of mafic microgranular enclaves; heterogeneous peralkaline composition; and wide ranges of MgO, Ni, and other trace elements suggest that the parental magma was mainly sourced from partial melting of Archean to Paleoproterozoic crustal sources, mixed with juvenile mantle-derived mafic magmas. The Mogou pluton was probably emplaced in the tectonic transition from syn-collision to post-collision settings and accompanying slab break-off process, from the commencement of collision at approximately 245 Ma and post-collisional extension at approximately 210 Ma. Gold, molybdenum, and copper deposits formed during the interval of 255-208 Ma, and the close temporal and spatial relationship between these Triassic polymetallic deposits and the Mogou alkaline pluton invokes a genetic linkage. The heat source for magmatismand related metallogeny is correlated to a hot upwelling asthenospheric mantle that caused partial melting of the Archean to Paleoproterozoic crustal basement, resulting in magma mixing between the two end-members.
