“…Thus, the major element contents show a negative correlation with the SiO 2 content (Figure a–c). In addition, with the evolution of the parent magma of the basaltic trachyandesite and trachyandesite, the Na 2 O/K 2 O and δ values gradually decrease (from 0.66 to 0.32 and from 8.32 to 2.48, respectively), which matches the patterns observed in the basaltic‐andesitic and trachyandesitic rocks elsewhere in the region (Li et al, ; Yin, Zhao, Zhao, & Zhang, ). In terms of trace and rare earth elements, in the primitive mantle‐normalized trace element spidergrams and chondrite‐normalized REE plots (Figure a,b), the basaltic‐andesitic and trachyandesitic rocks fall in the shaded area and have the same distribution pattern as the basic volcanic rocks in the Tamulangou Formation.…”

“…In addition, Ag‐rich Pb–Zn ore can often surround an independent Ag orebody (associated Ag reserves often reach the scale of large deposits) and generally contain high grades of various elements (such as Cd, Ga, Ge, In, Tl, Se, and Te; Yuan, Zhu, & Wang, ). Therefore, these deposits are of broad interest and have been studied by scholars both in China and internationally (Canet et al, ; Gantumur, Batulzii, Wang, & Zhu, ; Kovalenker, Naumov, Prokof'Ev, Jelen, & Gaber, ; Li, Liu, Xu, Li, & Zhang, ; Liu, Zhang, & Zhang, ; Mao et al, ; Nie, Li, Liu, & Ding, ; Qi, Chen, & Pirajno, ; Quan, Zhang, Wu, & Zhu, ; Shao et al, ; Shao et al, ; She et al, ; Wang, Fan, Wang, & Ma, ; Wang, Sun, & Zhong, ; Wang, Wang, Wang, & Chen, ; Wu, ; Wu, Zhao, Shao, Bao, & Wang, ; Zhang et al, ; Zhao, Xie, & Cheng, ).…”

The Derbur lead–zinc deposit is located in the Derbugan metallogenic belt in the north‐western portion of the Mesozoic Hailaer‐Genhe volcanic basin in the northern Great Xing'an Range. This deposit occurs in the Middle Jurassic intermediate–mafic volcanic rocks of the Tamulangou Formation and is spatially and temporally associated with acidic pyroclastic rocks. The host rocks are bedded trachyandesite and rhyolitic lithic‐crystal tuffs, and basaltic‐andesitic aplite veins are associated with the ore body. Because the deposit is a hypabyssal low‐temperature hydrothermal Pb–Zn deposit associated with volcanism, to determine the precise petrogenesis of the volcanic rocks, this study analysed the zircon U–Pb ages of the trachyandesite and rhyolitic lithic‐crystal tuffs, the Sr–Nd–Pb isotopic geochemistry of the trachyandesite and basaltic‐andesitic aplite, and the whole‐rock geochemistry of all three rock types. The results showed that the trachyandesite and basaltic‐andesitic aplite belong to the shoshonitic series and have similar whole‐rock and isotopic geochemical characteristics, including enrichments in large‐ion lithophile elements and light rare earth elements and depletions in high‐field‐strength elements. They also have low initial 87Sr/86Sr values of 0.705007–0.705240 and εNd(t) values of +0.6 to +1.7, with model ages (TDM) of 699–883 Ma. The ratios of 206Pb/204Pb, 207Pb/204Pb, and 208Pb/204Pb vary from 18.438 to 18.476, 15.570 to 15.577, and 38.254 to 38.320, respectively, with μ values of 9.40–9.41. In contrast, the rhyolitic lithic‐crystal tuffs are characterized by high SiO2 contents (73.44–79.48 wt.%); low Al2O3 (11.36–12.53 wt.%), TiO2 (0.14–0.18 wt.%), and K2O + Na2O (3.48–3.89 wt.%, Na2O ≤ K2O) contents; and low Mg# values (0.17–0.41), indicating that they belong to the calc–alkaline series. Additionally, they have relatively low REE contents and strong Sr depletions. LA‐ICP‐MS zircon U–Pb dating of the trachyandesite and rhyolitic lithic‐crystal tuffs indicates that their ages are 167.0 ± 2.0 Ma and 164.8 ± 1.6 Ma, respectively. We conclude that the trachyandesite and the basaltic‐andesitic aplite were derived from the partial melting of lower crustal material assimilated by a depleted lithospheric mantle that was subsequently metasomatized by subducted slab‐derived fluids. The rhyolitic lithic‐crystal tuffs likely originated from the partial melting of accreted lower crust. In summary, because the acidic volcanism was accompanied by increasingly felsic volcanism, bimodal volcanic rocks were produced. Among volcanogenic deposits, bimodal volcanic rocks are the most favourable ore‐hosting rocks, and ore‐forming materials were contributed by the magmatic system. These processes created conditions conducive to the formation of large‐scale Ag, Pb, and Zn mineralization in this area.

“…The third model states that the Mesozoic volcanic rocks in the Great Xing'an Range formed during closure of the Mongolia–Okhotsk Ocean, which resulted in stretching of the orogenic belt (Guo et al, ; Fan et al, ; Meng, ; Wang, Liu, Wang, & Song, ; Li, Liu, Xu, Li, & Zhang, ; Tang et al, ; Wang, Zhou, Zhang, Ying, & Zhang, ;Ying et al, ). Primary magma was derived from partial melting of crustal rocks in the Chaihe area of the middle Great Xing'an Range.…”

This paper reports on the petrography, geochemistry, and geochronology of late Mesozoic volcanic rocks in the Wenkutu area of the northern Great Xing'an Range, North‐east China, and discusses the formation age, petrogenesis, and tectonic environment of the Manketouebo, Manitu, Baiyingaolao, and Meiletu formations. Results of Zircon U–Pb dating show that the volcanic rocks in the Wenkutu area were formed during the Early Cretaceous (Manketouebo Formation at 145 ± 1 Ma, Manitu Formation at 141.3 ± 1.7 Ma, Baiyingaolao Formation at 128.7 ± 1.1 Ma, and Meiletu Formation at 129 ± 1 Ma). The Manketouebo, Manitu, and Baiyingaolao formations are dominated by intermediate to acid volcanic rocks that belong to the high‐K calc‐alkaline series, with Eu/Eu* values of 0.38–0.84.They are enriched in light rare earth elements (LREE) and depleted in heavy rare earth elements (HREE). The Meiletu Formation is dominated by intermediate to basic volcanic rocks, belongs to the high‐K calc‐alkaline series, has Eu/Eu* values of 0.89–0.97, and is enriched in Ba, K, Th, U, La, Ce, Sr, Nd, and Hf but relatively depleted in Nb, Ta, Zr, P, and Ti, with no obvious fractionation of LREE and HREE. Results indicate that the magma of the Manketouebo, Manitu, and Baiyingaolao formations had a crustal origin, whereas the Meiletu Formation was sourced from the mantle and subsequently contaminated by crustal materials. The late Mesozoic volcanic rocks in the study area were formed during an orogenic stage, and the compressional environment was caused by subduction of the paleo‐Pacific Plate below the Asian continental plate.

The origin and geodynamic evolution of peak Early Cretaceous magmatism in the southern Great Xing'an Range, North China, have long been controversial. Here we report new U‐Pb zircon ages (141–129 Ma) of a suite of dioritic‐granitic rocks from central Inner Mongolia, far from the sutures or plate boundaries of the Paleo‐Pacific and Mongol‐Okhotsk oceans, thus delineating an Early Cretaceous intracontinental magmatic province, which had a peak activity at 130–120 Ma. Dioritic suite including diorite, tonalite, and granodiorite shows variable zircon εHf(t) of +1.4 to + 11.8 and δ18O values of +5.7 to +6.9‰, while granitic suite consisting of monzogranite, syenogranite, and granite porphyry also records variable zircon εHf(t) of −0.9 to +15.0 and δ18O values of +6.3 to +8.1‰, suggesting crustal melting by preexisting crustal source with important recycled supracrustal components including fluids. Furthermore, these rocks show variable whole‐rock δ7Li values (−0.6 to +12.1‰), indicating fluids played an important role in magma source. We propose a deep‐sourced water‐fluxed melting scenario by ancient hydrous slabs inherited from the Paleo‐Asian Ocean that were trapped in the deep interior, thus releasing aqueous fluids to melt the lithospheric mantle and produce water‐rich mafic magmas. These mafic magmas were underplated into crust where they promoted water‐fluxed partial melting to generate the large‐scale Early Cretaceous magmatism in the southern Great Xing'an Range. Such melting due to fluxing of aqueous fluids was probably operating as a widespread process responsible for the Early Cretaceous dramatically tectonomagmatic events and evolution of continental crust in NE Asia.
