“…Previous researchers have concluded that the Late Mesozoic (Jurassic-Cretaceous) volcanic rocks, which are widely distributed in NE China, including the Great Xing'an Range, can be divided into three major volcanism stages: Early Jurassic (193-174 Ma, peak at 182 Ma), Late Jurassic-early Early Cretaceous (163-136 Ma, peak at 139 Ma), and late Early Cretaceous (136-106 Ma, peak at 128 Ma) (Ji et al, 2019). The Early Jurassic volcanic rocks are mainly distributed close to the southern margin of the Mongol-Okhotsk Suture Belt and are considered to be formed in an active continental margin environment, which is related to the southwards subduction of the Mongol-Okhotsk oceanic plate under the Erguna block Wang Z J et al, 2015).…”

“…In the Late Jurassic-late Early Cretaceous, the lithosphere in the region went through a setting of extensional thinning before crustal thickening due to the closure of the Mongol-Okhotsk Ocean Ji et al, 2018;. Although in the Late Mesozoic, the Paleo-Pacific plate also caused an important impact of magmatism in NE China, such as the rocks young towards the southeast in the Songliao block-Jiamusi block Ji et al, 2019), the volcanic rocks we studied in the Keyihe area and the crust-derived rock sequences distributed around them show that they are not affected by the Paleo-Pacific tectonic regime. As mentioned earlier, the Keyihe adakitic rocks have lower Mg # , Cr and higher K 2 O, Th values, indicating that they are mainly affected by the Mongol-Okhotsk tectonic regime.…”

A large amount of igneous rocks in NE China formed in an extensional setting during Late Mesozoic. However, there is still controversy about how the Mongol-Okhotsk Ocean and the Paleo-Pacific Ocean effected the lithosphere in NE China. In this paper, we carried out a comprehensive study for andesites from the Keyihe area using LA-ICP-MS zircon U-Pb dating and geochemical and Hf isotopic analysis to investigate the petrogenesis and tectonic setting of these andesites. The U-Pb dating yields an Early Cretaceous crystallization age of 128.3±0.4 Ma. Geochemically, the andesites contain high Sr (686-930 ppm) and HREE contents, low Y (11.9-19.8 ppm) and Yb (1.08-1.52 ppm) contents, and they therefore have high Sr/Y (42-63) and La/Yb (24-36) ratios, showing the characteristics of adakitic rocks. Moreover, they exhibit high K 2 O/Na 2 O ratios (0.57-0.81), low MgO contents (0.77-3.06 wt%), low Mg # value (17-49) and negative ε Hf (t) values (−1.7 to −8.5) with no negative Eu anomalies, indicating that they are not related to the oceanic plate subduction. Based on the geochemical and isotopic data provided in this paper and regional geological data, it can be concluded that the Keyihe adakitic rocks were affected by the Mongol-Okhotsk tectonic regime, forming in a transition setting from crustal thickening to regional extension thinning. They were derived from the partial melting of the thickened lower crust. The closure of the Mongol-Okhotsk Ocean may finish in early Early Cretaceous, followed by the collisional orogenic process. The southern part region of its suture belt was in a post-orogenic extensional setting in the late Early Cretaceous.

“…NE China is the easternmost part of CAOB, and it is characterized by abundant granitoid, exposed over an area of about 200,000 km 2 . For the past decade, precise geochronological work has been done in NE China, which is marked by large scale Mesozoic magmatism, forming a key part of Mesozoic magmatic belt in CAOB (Wu et al, 2002Ge et al, 2005;Cheng et al, 2006;Zhang et al, 2008Zhang et al, , 2018Wilde et al, 2010;She et al, 2012;Wang et al, 2012aWang et al, , b, 2015Wang et al, , 2019Gao et al, 2013;Shi et al, 2013Shi et al, , 2015Yu et al, 2013a, b;Li et al, 2014Li et al, , 2015aLi et al, , b, 2018aBi et al, 2015;Chen et al, 2015;Tian et al, 2015;Dong et al, 2016a;Ji et al, 2016aJi et al, , b, 2018aJi et al, , 2019He et al, 2017He et al, , 2018Xie et al, 2017;Xu et al, 2018;Yin et al, 2018). However, its geodynamic mechanism and evolution still remain controversial (Zhang et al, 2010a, b;Wu et al, 2011;She et al, 2012;Wang et al, 2012aWang et al, , b, 2015Shi et al, , 2015Xu et al, 2013a, b;Tian et al, 2015;Dong et al, 2014Dong et al, , 2016aLi et al, 2014…”

“…Unlike other areas in CAOB, NE China can be thought of as one of the important areas of eastern Asian active continental margin, and therefore it was commonly considered that the tectonic evolution of NE China was controlled by the Paleo-Pacific tectonic regime (Zhang et al, 2010a, b;Tian et al, 2015;Dong et al, 2014Dong et al, , 2016aHe et al, 2017He et al, , 2018Xie et al, 2017). In the past decade, some studies have suggested that a double-side subduction is favored for the tectonic evolution of Mongol-Okhotsk Ocean, and the Mongol-Okhotsk tectonic regime probably plays an important role in the Mesozoic magmatism and tectonic evolution in NE China (Wang et al, 2012aLi et al, 2014Li et al, , 2015aLi et al, , b, 2018aTang et al, 2014Tang et al, , 2016Ji et al, 2016aJi et al, , b, 2018aJi et al, , 2019. Therefore, and the deep geodynamic background of Mesozoic igneous rocks in NE China remains unclear.…”

“…Therefore, and the deep geodynamic background of Mesozoic igneous rocks in NE China remains unclear. NE China might have undergone combined effect of the Paleo-Pacific and Mongol-Okhotsk tectonic regimes, implying a complex tectonic evolutionary history (Zhang et al, 2010a, b;Wu et al, 2011;She et al, 2012;Wang et al, 2012aWang et al, , b, 2015Shi et al, , 2015Xu et al, 2013a, b;Tian et al, 2015;Dong et al, 2014Dong et al, , 2016aLi et al, 2014Li et al, , 2015aLi et al, , b, 2018aTang et al, 2014Tang et al, , 2016Ji et al, 2016aJi et al, , b, 2018aJi et al, , 2019He et al, 2017He et al, , 2018Xie et al, 2017). Thus, one question can be posed: which regime was predominantly responsible for the Mesozoic magmatism and tectonic evolution in NE China?…”

In this study, we present zircon U-Pb ages, whole-rock geochemical data and Hf isotopic compositions for the Meiguifeng and Arxan plutons in Xing'an Massif, Great Xing'an Range, which can provide important information in deciphering both Mesozoic magmatism and tectonic evolution of NE China. The zircon U-Pb dating results indicate that alkali feldspar granite from Meiguifeng pluton was emplaced at ~145 to 137 Ma, and granite porphyry of Arxan pluton was formed at ~129 Ma. The Meiguifeng and Arxan plutons have similar geochemical features, which are characterized by high silica, total alkalis, differentiation index, with low P 2 O 5 , CaO, MgO, TFe 2 O 3 contents. They belong to high-K calc-alkaline series, and show weakly peraluminous characteristics. The Meiguifeng and Arxan plutons are both enriched in LREEs and LILEs (e.g., Rb, Th, U and K), and depleted in HREEs and HFSEs (e.g., Nb, Ta and Ti). Combined with the petrological and geochemical features, the Meiguifeng and Arxan plutons show highly fractionated I-type granite affinity. Moreover, the Meiguifeng and Arxan plutons may share a common or similar magma source, and they were probably generated by partial melting of Neoproterozoic high-K basaltic crust. Meanwhile, plagioclase, K-feldspar, biotite, apatite, monazite, allanite and Ti-bearing phases fractionated from the magma during formation of Meiguifeng and Arxan plutons. Combined with spatial distribution and temporal evolution, we assume that the generation of Early Cretaceous Meiguifeng and Arxan plutons in Great Xing'an Range was closely related to the break-off of Mudanjiang oceanic plate. Furthermore, the Mudanjiang Ocean was probably a branch of Paleo-Pacific Ocean.

The Hailar–Tamtsag Basin (HTB), an important component of the late Mesozoic extensional basin system in Northeast (NE) China, is characterized by episodic rifting, dramatic magmatism, and thick terrestrial sediments, which provides crucial opportunities to understand late Mesozoic tectonomagmatic events in NE China. However, the previously established late Mesozoic chronostratigraphic framework in the basin remains problematic due to limited isotopic chronological constraints. Here, we present 28 new zircon U–Pb ages for the volcanic rocks from the HTB, which allow us to establish a refined chronostratigraphic framework for the late Mesozoic terrestrial strata. Newly calibrated results indicate that the depositional ages of the Tamulangou and Tongbomiao formations are constrained to ca. 157–148 and ca. 142–137 Ma, respectively; the depositional ages of the Lower Nantun and Upper Nantun members are constrained to ca. 131–120 and ca. 117–111 Ma, respectively. Combining these results with previous studies on sedimentation, structural deformation, and magmatism, the Late Jurassic–Early Cretaceous tectonostratigraphic evolution of the HTB is reconstructed, and three major phases of intracontinental deformation are identified. The HTB experienced extensional deformation in the Late Jurassic due to the break‐off of the subducted oceanic slab of the Mongol–Okhotsk Ocean and subsequent gravitational collapse of orogenically thickened crust following the closure of the ocean basin. Then, in the latest Jurassic–earliest Cretaceous, the evolution of the HTB was dominated by compressional deformation related to flat‐slab subduction of the Paleo‐Pacific Plate. During the Early Cretaceous, an extensional regime resumed in the HTB in response to rollback of the subducting Paleo‐Pacific Plate.
