“…Scissor-type closure of the Palaeo-Asian Ocean occurred during the Late Permian -Middle Triassic period along the Solonker-Changchun-Yanji suture zone, which led to soft collision of the North China and Siberian cratons (Li, 2006;Eizenhöfer et al 2015). Since the Mesozoic Era, the XMOB has been affected primarily by closure of the MOO and subduction of the Palaeo-Pacific Plate, leading to the widespread occurrence of Mesozoic volcanic rocks and coeval granitoid intrusions (Zhang et al 2010;Xu et al 2013;Zhou et al 2014;Yang et al 2016;Guan et al 2018;Li et al 2019;Suo et al 2019).…”

“…Basins) (Meng et al 2003;Ji et al 2019a, b). Nevertheless, the specific geodynamic processes that led to the extensional tectonic setting remain contentious, with the various schemes proposed including (1) upwelling of a mantle plume (Lin et al 1998;Ge et al 2000); (2) gravitational collapse of orogenically thickened crust after closure of the Mongol-Okhotsk Ocean (MOO) (Fan et al 2003;Meng et al 2003;Xu et al 2008;Ying et al 2010;Guan et al 2018); (3) large-scale lithospheric delamination related to subduction of the Palaeo-Pacific Plate (Wu et al 2005(Wu et al , 2011Zhang et al 2010;Li et al 2019;Suo et al 2019); and (4) rollback of the subducted Palaeo-Pacific flat slab and subsequent upwelling of asthenospheric mantle (Ji et al 2019a, b). However, regardless of the particular geodynamic processes that were involved, intense crust-mantle interactions and vertical accretion of continental crust are expected to have occurred in the GXR during the Early Cretaceous Epoch, as indicated by the upwelling of asthenospheric-mantle materials to various degrees.…”

Late Mesozoic igneous rocks are important for deciphering the Mesozoic tectonic setting of NE China. In this paper, we present whole-rock geochemical data, zircon U–Pb ages and Lu–Hf isotope data for Early Cretaceous volcanic rocks from the Tulihe area of the northern Great Xing’an Range (GXR), with the aim of evaluating the petrogenesis and genetic relationships of these rocks, inferring crust–mantle interactions and better constraining extension-related geodynamic processes in the GXR. Zircon U–Pb ages indicate that the rhyolites and trachytic volcanic rocks formed during late Early Cretaceous time (c. 130–126 Ma). Geochemically, the highly fractionated I-type rhyolites exhibit high-K calc-alkaline, metaluminous to weakly peraluminous characteristics. They are enriched in light rare earth elements (LREEs) and large-ion lithophile elements (LILEs) but depleted in high-field-strength elements (HFSEs), with their magmatic zircons ϵHf(t) values ranging from +4.1 to +9.0. These features suggest that the rhyolites were derived from the partial melting of a dominantly juvenile, K-rich basaltic lower crust. The trachytic volcanic rocks are high-K calc-alkaline series and exhibit metaluminous characteristics. They have a wide range of zircon ϵHf(t) values (−17.8 to +12.9), indicating that these trachytic volcanic rocks originated from a dominantly lithospheric-mantle source with the involvement of asthenospheric mantle materials, and subsequently underwent extensive assimilation and fractional crystallization processes. Combining our results and the spatiotemporal migration of the late Early Cretaceous magmatic events, we propose that intense Early Cretaceous crust–mantle interaction took place within the northern GXR, and possibly the whole of NE China, and that it was related to the upwelling of asthenospheric mantle induced by rollback of the Palaeo-Pacific flat-subducting slab.

Petrogenesis and tectonic implications of Late Mesozoic volcanic rocks in the northern and central Great Xing'an Range, NE China: Constraints from geochronology and geochemistry

et al. 2020

In the northern and central Great Xing'an Range, there exist widespread Late Mesozoic volcanic rocks, of which the petrogenesis and geodynamic setting remain controversial. These rocks are composed of andesite, trachyandesite, basaltic andesite, and rhyolite. This study presents new data of zircon U-Pb dating, Hf isotopic composition, and whole-rock geochemistry of the Late Jurassic intermediate-mafic volcanic rocks within the northern Great Xing'an Range. In addition, the geochronological and geochemical data for the Late Mesozoic intermediate-mafic rocks within the northern and central Great Xing'an Range are summarized for constraining the geochronological framework, petrogenesis, and geodynamic setting of the large-scale Late Mesozoic volcanism in this region. The intermediate-mafic volcanic rocks are enriched in large-ion lithophiles and light rare earth elements and are depleted in high-fieldstrength elements such as Nb, Ta, and Ti, with positive ε Hf (t) values (+0.7 to +15.4). The data indicate that the volcanic rocks were derived from the partial melting of a mantle wedge that was modified by previously subducted slab-derived fluids. These Late Mesozoic intermediate-mafic volcanic rocks record a post-collisional lithospheric extensional setting resulting from the closure of the Mongol-Okhotsk Ocean.

“…The NNE-trending GXR lies in the western segment of NE China and maintains a record of abundant magmatism since the Phanerozoic (Figure 1c) [23,33,39,55,71]. The GXR comprises various structure-rock assemblages connected with Paleozoic island-arc evolution theories, including without the limitation of shallow-sea limestones, metamorphic and volcanic sedimentary rocks, fine-grained clastic rocks, and widespread igneous intrusions [2,39], and is almost overlaid by voluminous Mesozoic magmatite [3,38,39]. The Mesozoic magmatite primarily involves the extensive allocation of the Late Jurassic-Early Cretaceous volcanics [16,17] and the Late Triassic-Middle Jurassic and Early Cretaceous granitoids (Figure 1c) [38,68,76].…”

“…Northeast (NE) China, which is well-known for its extensive distribution of Late Mesozoic igneous rocks [1][2][3][4][5][6][7][8], is situated in the eastern segment of the Central Asian Orogenic Belt and bounded by the northern part of the North China Craton, the southern part of the Siberia Craton and the western Pacific rim (Figure 1a) [9][10][11][12][13][14][15][16][17][18][19][20]. During the Late Mesozoic, this region experienced multi-stage structural superposition and tectonic reformation of the Paleo-Pacific Ocean (PPO) and Mongol-Okhotsk Ocean tectonic domains, recording multiple tectonic-thermal events of different scales by widespread intrusive rocks [13,[21][22][23][24][25][26][27].…”

Abundant Early Cretaceous magmatism is conserved in the central and southern Great Xing’an Range (GXR) and has significant geodynamic implications for the study of the Late Mesozoic tectonic framework of northeast China. In this study, we provide new high-precision U–Pb zircon geochronology, whole-rock geochemistry, and zircon Hf isotopic data for representative intrusive rocks from the northern part of the Ulanhot area to illustrate the petrogenesis types and magma source of these rocks and evaluate the tectonic setting of the central-southern GXR. Laser ablation inductively coupled plasma–mass spectrometry (LA-ICP-MS) zircon U–Pb dating showed that magmatism in the Ulanhot area (monzonite porphyry: 128.07 ± 0.62 Ma, quartz monzonite porphyry: 127.47 ± 0.36, quartz porphyry: 124.85 ± 0.34, and granite porphyry: 124.15 ± 0.31 Ma) occurred during the Early Cretaceous. Geochemically, monzonite porphyry belongs to the metaluminous and alkaline series rocks and is characterized by high Al2O3 (average 17.74 wt.%) and TiO2 (average 0.88 wt.%) and low Ni (average 4.63 ppm), Cr (average 6.69 ppm), Mg# (average 31.11), Y (average 15.16 ppm), and Yb (average 1.62 ppm) content with enrichment in Ba, K, Pb, Sr, Zr, and Hf and depletion in Ti, Nb, and Ta. The granitic rocks (e.g., quartz monzonite porphyry, quartz porphyry, and granite porphyry) pertain to the category of high-K calc-alkaline rocks and are characterized by high SiO2 content (>66 wt.%) and low MgO (average 0.69 wt.%), Mg# (average 31.49 ppm), Ni (average 2.78 ppm), and Cr (average 8.10 ppm) content, showing an affinity to I-type granite accompanied by Nb, Ta, P, and Ti depletion and negative Eu anomalies (δEu = 0.57–0.96; average 0.82). The Hf isotopic data suggest that these rocks were the product of the partial melting of juvenile crustal rocks. Notably, fractionation crystallization plays a crucial role in the process of magma emplacement. Combining our study with published ones, we proposed that the Early Cretaceous intrusive rocks in the Ulanhot area were formed in an extensional tectonic background and compactly related to the subduction of the Paleo-Pacific Ocean plate.
