The presence of a metasomatized lithospheric mantle beneath the southern margin of the NCC has also been supported by the emplacement of many intrusions, including the 245-210 Ma Mogou alkali pluton Lu, Liang, Bai, & Lu, 2013;He et al, 2016), the 225-209 Ma Huangshuian and Huanglongpu carbonatites (Stein et al, 1997;Huang, Wu, Du, & He, 1994;Huang, Hou, Yang, Li, & Xu, 2009;Du et al, 2004;Xu et al, 2011a;Cao et al, 2014;Song et al, 2015Song et al, , 2016, the ca.160 Ma Xinyang peridotitic xenolithos (Zheng, Sun, Zhou, & Robinson, 2005, Zheng et al, 2008; enriched by South China), the 129 Ma Huanglongpu diabase dikes (Zhao, Mao, Ye, Xie, & Yang, 2010), and the 122 Ma Tianqiaogou monzodiorites (Gao, Zhao, Bao, & Yang, 2014).…”

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 late Mesozoic magmatic plutons and granite porphyries in the Xiong'ershan area include the Wuzhangshan, Haoping, Jinshanmiao, Haopinggou, Heyu and Taishanmiao granite plutons and the Leimengou, Banzhusi, Qiyugou and Shiyaogou granite porphyries. Available published data have provided good constraints for the crystallization age of these plutons and granite porphyries [2,12,18,19,21,42,55,[87][88][89][90][91][92]. The late Mesozoic magmatic event in the Xiong'ershan area principally proceeded for 60 Ma, and we suggest that three main magmatic events occurred from 177-153 Ma (Wuzhangshan pluton) [89,90], 145-125 Ma (most of the plutons and granite porphyries mentioned above except for the Wuzhangshan and Taishanmiao granite plutons) [2,18,19,21,42,55,[87][88][89][90][91][92] and 125-115 Ma (Taishanmiao pluton) [12].…”

The Banzhusi granite porphyry is located in the Xiong’ershan area, East Qinling orogenic belt (EQOB). This study presents an integrated whole-rock geochemistry and zircon U-Pb-Hf-O isotope analysis of the Banzhusi granite porphyry. These rocks have metaluminous, high-K alkali-calcic and shoshonitic features and show significant enrichment in light rare earth elements (LREEs) over heavy rare earth elements (HREEs) with negative Eu anomalies. These samples are also greatly enriched in Rb, Ba, K, Pb, Th and U and depleted in Nb, Ta, P and Ti, and they mostly overlap the ranges of the Taihua Group tonalite–trondhjemite–granodiorite (TTG) gneiss. Magmatic zircons from three samples of the Banzhusi granite porphyry yield U-Pb ages of 125.1 ± 0.97 Ma, 128.1 ± 1.2 Ma and 128.2 ± 1.3 Ma. The Hf-O isotope features of zircons from the three samples are very similar (δ18Ozircon = 4.84‰ to 6.51‰, εHf(t) = −26.9 to −14.4). The co-variations of geochemical and isotopic data in these granite porphyries imply that the Banzhusi granite porphyry resulted from the mixing of the partially melted Taihua Group and mantle-derived material in a post-collisional setting from 128–125 Ma.

“…Intracontinental magmatism occurring in different tectonic settings has been attributed to several possible processes, such as deep mantle plumes, back-arc spreading, continental rifting, stagnant slab, and lithospheric thinning (e.g. Gao et al 2004Gao et al , 2014Kuritani et al 2009Kuritani et al , 2017Zhao et al 2012;Van der Meer et al 2017). This suggests that the origins of intracontinental magmatism require detailed investigations in each individual setting (Kuritani et al 2009).…”

“…In addition to the Triassic magmatism, the southern margin of the NCC in the QOB also records intensive intracontinental tectonic-magmatic activity during the Late Jurassic to Early Cretaceous, with widely exposed igneous rocks (e.g. Mao et al 2010;Zhao et al 2012;Gao et al 2014;Gao & Zhao, 2017) and many worldclass Mo-Au-Ag-Pb-Zn ore deposits (e.g. Mao et al 2002Mao et al , 2011Chen et al 2008;Tang et al 2013;Tang, 2014;Bao et al 2017;Tian et al 2017).…”

“…Late Jurassic to Early Cretaceous granites along the southern margin of the NCC have been extensively studied in the past decades, but there is still considerable uncertainty about key issues related to these magmatic rocks, such as (1) the petrogenesis of these rocks: these granites have been proposed to be derived from partial melting of ancient crystalline basement of the NCC, which mixed with mantle-derived melts (e.g. Li et al 2012;Gao et al 2014;Gao & Zhao, 2017), or from the subducted continental crust of the northern margin of the Yangtze Craton (e.g. Bao et al 2014Bao et al , 2017;…”

The Xiong’ershan area is the third largest gold-producing district in China. The Late Jurassic to Early Cretaceous magmatism in the Xiong’ershan area can be divided into two episodes: early (165–150 Ma) and late (138–113 Ma). Laser ablation – inductively coupled plasma – mass spectrometry (LA-ICP-MS) zircon U–Pb dating yields ages of 160.7 ± 0.6 Ma and 127.2 ± 1.0 Ma for the Wuzhangshan and Huashan monzogranites in the Xiong’ershan area, respectively, representing the two magmatic episodes. The Wuzhangshan monzogranites exhibit adakite-like geochemical features (e.g. high Sr/Y ratios, low Yb and Y contents). Their Sr–Nd–Hf isotopic compositions are consistent with those of the amphibolites of the Taihua Group, indicating that the Wuzhangshan monzogranites were formed from partial melting of the Taihua Group metamorphic rocks. Compared to the Wuzhangshan rocks, the Huashan monzogranites have higher MgO, Cr, Co and Ni contents, but lower Sr/Y and Fe3+/Fe2+. All the samples from the Huashan monzogranites plot in the area between the Taihua Group amphibolite rocks and the mantle rocks in the (87Sr/86Sr)t vs εNd(t) and age vs εHf(t) diagrams, suggesting that the Huashan monzogranites were probably generated by mixing of mantle-derived magmas and the Taihua Group metamorphic basement melts. The gold mineralization (136–110 Ma) is coeval with the emplacement of the late-episode magmas, implying that crustal–mantle mixed magma might be a better target for gold mineralization compared to the ancient metamorphic basement melt. The data presented in this study further indicate that the transformation of the lithosphere from thickening to thinning in the Xiong’ershan area probably occurred between ~160 Ma and ~127 Ma, and that the gold mineralization in this area was probably related to lithospheric thinning.
