“…Traditionally, these micro‐blocks were considered as micro‐continental massifs with Precambrian basements according to a suite of amphibolite‐facies metamorphic rocks, so‐called the Xinghuadukou “Group,” of which all the lithologic formations were referred to be Neoproterozoic age (Heilongjiang Bureau of Geology and Mineral Resources, ; Inner Mongolia Bureau of Geology and Mineral Resources, ). However, recent geochronological studies on this “group” have revealed that these rocks are associated metaigneous and metasedimentary rock units with various formation ages ranging from the Late Palaeoproterozoic to Early Cambrian and a relatively uniform metamorphic age similar to 500 Ma (Biao, Li, He, Zhou, & Ma, ; Ge et al, ; Miao et al, ; Sun, Ren, Zhao, Ji, & Geng, ; Wu, Chen, Chen, & Zeng, ; Xu et al, ; Zhou, Wilde, Zhang, Ren, & Zheng, ). Currently, it is called the Xinghuadukou Complex.…”

“…However, study on the Xinghuadukou Complex is limited. Almost all available data are from the metamorphic supracrustal rocks (khondalite series defined by Zhou, Wilde, Zhang, Zhao, et al, ) of this complex (Ge et al, ; Miao et al, ; Wu et al, ; Xu et al, ; Zhou, Wilde, Zhang, Ren, & Zheng, ). The only reliable SHRIMP and LA‐ICP‐MS zircon U–Pb dating for the orthogneiss of this complex was reported from the Hanjiayuanzi area, which yielded Late Palaeoproterozoic ages, similar to 1.8 Ga (Sun, Ren, et al, ).…”

This study reports new LA‐ICP‐MS U–Pb zircon ages from the Xinghuadukou Complex from the Erguna Block, NE China. A suite of the Palaeoproterozoic orthogneiss and a suite of the Vendian to Cambrian paragneiss are recognized with the co‐magmatic age of 2,464 ± 26 Ma and the maximum depositional age of 561 ± 10 Ma for their igneous and sedimentary protolith, respectively. The trace element geochemical analysis suggests a strong arc affinity for our orthogneiss, characterized by the enriched LREE and LILE, the elevated incompatible and fluid‐mobile elements and the depleted yet negligible fractionated HREE and HFSE. By comparing our samples with a suite of Cenozoic mantle‐derived granitoids from Hokkaido and a suite of Mesozoic active continental margin volcanics from NE China, it is suggested that the igneous protolith of our near Archaean orthogneiss formed in an arc environment and probably derived from the prior arc crust. The trace element features of the paragneiss highly resemble that of the orthogneiss, showing arc affinity, which suggests an arc basin environment for the sedimentary protolith of our Vendian to Cambrian paragneiss. Based on the synthesized evidence from the Xinghuadukou Complex, a new tectonic scenario is proposed that the basement of the Erguna Block might be forged by the accretion and collision of multi‐episodic igneous arcs and their correlated arc basins, which was probably lasting through the Proterozoic and followed by the Pan‐African period high‐grade metamorphism. The consolidated Erguna Block was later involved into the CAOB tectonic domain, modified and disrupted with the assembly of NE China.

“…This area records evidence for several regional tectonic events, including the collision between the Songnen and Bulieya–Jiamusi massifs (Neoproterozoic–Early Cambrian), the Xing'an and Erguna massifs (Early Palaeozoic), the Songnen and Xing'an massifs (Late Palaeozoic), and the North China Plate and the Mongolian Xing'an Massif (Late Palaeozoic; She et al, ; Zhang et al, ; Zhou, Simon, Wilde, Ren, & Zheng, ). The intrusive rocks in this area have complex petrogenesis and geochemical characteristics and have therefore been the subject of numerous studies (e.g., Ge et al, ; Jia, Wei, Gong, & Zhao, ; Liu et al, ; Ouyang, Mao, Zhou, & Su, ; Zheng, Zhang, & Xu, ).…”

The occurrence of igneous rocks within the Wenkutu area, northeastern China, allows the Late Palaeozoic–Mesozoic geodynamic setting of the Great Xing'an Range to be investigated. Here, we present petrographic, geochemical, and geochronological data for intrusive rocks within the Wenkutu area. Zircon U–Pb geochronology reveals that magmatism occurred during the Early Carboniferous (ca. 334 Ma), Early Permian (ca. 296 Ma), Middle Jurassic (ca. 170 Ma), and Early Cretaceous (ca. 130 Ma). The Early Carboniferous intrusive rocks are intermediate–mafic, metaluminous, and medium‐K calc‐alkaline, have low SiO2 (49.57–55.00 wt.%) and high MgO (3.00–4.77 wt.%), Cr (average 60.64 ppm), and Ni (average 24.73 ppm) contents, and high Mg# (average 45.1) values. These features, together with their significant depletion in Nb, Ta, and Ti, and their enriched Sr–Nd isotopic compositions, suggest that these Early Carboniferous rocks were derived from the mantle and subsequently contaminated by crustal material. The Early Permian, Middle Jurassic, and Early Cretaceous intrusive rocks are intermediate–acidic, peraluminous, and high‐K calc‐alkaline, enriched in light rare‐earth elements, Rb, Th, U, K, P, and Hf, relatively depleted in heavy rare‐earth elements, Nb, Ta, and Ti, and have Eu/Eu* values of 0.05–0.86. These features indicate that the rocks were derived by the partial melting of lower crust. Our results, together with those of previous studies, suggest that the Late Palaeozoic intrusive rocks formed during collision between the Songnen and Xing'an massifs. The Early Permian intrusive rocks formed during the transition from an orogenic to a non‐orogenic environment. The Middle Jurassic intrusive rocks formed during the closure of the Mongol–Okhotsk Ocean (MOO) and were emplaced along the western part of the suture zone. The Early Cretaceous intrusive rocks formed during non‐orogenic extension and were related to the final closure of the MOO or to rollback of the Palaeo‐Pacific Plate.

“…This area has experienced large‐scale tectonic movements, such as the collisions between the Songnen and Bulieya–Jiamusi massifs, the Xing'an and Eergu'Na massifs, and the Songnen and Xing'an massifs; collision of the Northern China Plate with the Mongolia Xing'an Massif; subduction of the Mongolia Okhotsk Ocean; and oblique subduction of the paleo‐Pacific Plate and subduction of the Pacific Plate (She et al, ; Zhang et al, ; Zhou, Simon, Wilde, Ren, & Zheng, ). The volcanic rocks in the area are complex in terms of their tectonic origins and geochemical characteristics and have therefore been the subject of numerous studies (e.g., Ge et al, ; Jia, Wei, Gong, & Zhao, ; Liu et al, ; Ouyang, Mao, Zhou, & Su, ; Zheng, Zhang, & Xu, ).…”

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.
