“…The results of geophysical and topographic research reveal that the destruction of the NCC occurred mainly in the east of the gravity gradient zone, while the west area still maintains the typical craton essence (Chen, 2010; Chen et al, 2006; Menzies et al, 2007; Xu, 2007; Xu et al, 2008; Zhu et al, 2011), which reflects the westward subduction of the Palaeo‐Pacific Plate beneath NE Asia. The distribution range of Stage 1, Stage 2 and Stage 3 igneous rocks indicates that Cretaceous magmatism gradually migrated eastward from the interior to the continental margin (Figure 11b; Sun, 2016; Tang et al, 2018; Wang et al, 2019), most likely as a result of the eastward drift of Eurasia caused by the continuous retreat of the Palaeo‐Pacific Plate during westward subduction (Sun, 2016; Tang et al, 2018). Moreover, the propagation of extensional fault zones through the overriding crust usually occurs in response to a slab roll‐back geodynamic mechanism (Menant et al, 2016).…”

“…The age histogram of the igneous rocks in eastern NE Asia shows that there are three peaks of magmatism, namely Stage 1 (132-104 Ma), Stage 2 (96-82 Ma) and Stage 3 (76-66 Ma) (Figure 11a; Table S4), corresponding to three different magmatism distribution trends (Figure 11b). It is not difficult to find that the mafic dikes of the above three periods were widely distributed in mainly in the east of the gravity gradient zone, while the west area still maintains the typical craton essence (Chen, 2010;Chen et al, 2006;Menzies et al, 2007;Xu, 2007;Xu et al, 2008;Zhu et al, 2011) Sun, 2016;Tang et al, 2018;Wang et al, 2019), most likely as a result of the eastward drift of Eurasia caused by the continuous retreat of the Palaeo-Pacific Plate during westward subduction (Sun, 2016;Tang et al, 2018).

We present zircon U–Pb ages, major and trace element analyses and zircon Hf isotope data on the Cretaceous mafic–felsic igneous rocks in the north‐eastern North China Craton (NCC) of NE China. These data have been used to discuss the petrogenesis of the mafic–felsic igneous rocks in order to constrain the geodynamical and magmatic evolution of the region. Zircon U–Pb dating results indicate that these igneous rocks crystallized during the Cretaceous (ca. 123–90 Ma). These mafic igneous rocks display low SiO2 contents, high MgO contents and marked enrichments in large‐ion lithophile elements (LILEs) and depletions in high‐field‐strength elements (HFSEs), combined with their εHf(t) values and La/Nb versus La/Ba diagram, suggesting they were derived from lithospheric mantle that experienced gradually increasing fluid metasomatism from 123 to 90 Ma. The felsic igneous rocks with high SiO2 values are metaluminous to weakly peraluminous and belong to the high–K calc–alkaline series. These felsic igneous rocks are all enriched in light rare earth elements (LREEs) and LILEs and relatively depleted in HFSEs, with barely negative Eu anomalies, combined with their εHf(t) values, these felsic igneous rocks were derived from partial melting of a lower crust. A synthesis of these new data with previous researches shows that the subduction and rollback of the Palaeo‐Pacific slab played a major role in the destruction of the north‐eastern NCC. The diagenetic temperatures of igneous rocks indicate that the mechanism of destruction of the NCC may be heterogeneous, most likely a thermal erosion mechanism in eastern Jilin area and a delamination mechanism in Liaodong Peninsula.

“…In the present study, the later period of Middle Triassic quartz diorites could be derived from the partial melting of a thickened lower crust accompanied by the final closure of the PAO. Remarkably, the Late Triassic magmatism consists of a suite of bimodal igneous rocks formed in a post‐orogenic extensional environment after the closure of the PAO along the Dunhua‐Mishan‐Huifahe‐Gudonghe Suture between CAOB and NCC (Figure 11, Cao et al, 2013; Wang et al, 2015; Wu et al, 2011; Xu et al, 2013; Yan et al, 1999). The Late Triassic was the peak metallogenic epoch of the copper–nickel sulphide deposit, represented by the Hongqiling super large copper–nickel sulphide deposit formed 236–208 Ma (Han et al, 2014; Hao et al, 2013; Wei et al, 2013, 2015, 2019; Wu et al, 2004; Xi et al, 2005).…”

The Hongqiling-Piaohechuan region in the east Central Asian Orogenic Belt (CAOB) is an economically important Ni-Cu sulphide mineralization region in China. It is widely accepted that these Ni-Cu sulphide deposits mainly formed during the Late Triassic period. The early Middle Triassic mafic-ultramafic plutons are therefore key in understanding the mineralization process. Here, we report the laser ablation inductively coupled plasma mass spectrometer (LA-ICP-MS) U-Pb dating of zircon and geochemical data for two Middle Triassic mafic-ultramafic plutons and one felsic pluton in central and eastern Jilin Province, NE China. The mafic-ultramafic plutons are composed of gabbronorite and olivine websterite. Zircon dating results indicate that these mafic-ultramafic plutons crystallized at 243 ± 1 to 245 ± 1 Ma in the Middle Triassic. The coeval felsic pluton is mainly quartz diorite. Zircon dating results indicate that the felsic pluton crystallized at 239.7 ± 0.63 Ma in the later period of Middle Triassic. The mafic-ultramafic plutons are low in SiO 2 (43.49-49.66 wt%), depleted in K 2 O (0.28-2.74 wt%) and Na 2 O (0.70-1.18 wt%). They have low rare earth element (REE) abundances without Eu anomalies, exhibit depletion in high-field-strength elements (HFSEs), and hold various ε Hf (t) values (À15.3 to +2.9). These findings suggest that the primary magma of mafic-ultramafic plutons was derived from the partial melting of the depleted lithospheric mantle, metasomatized by subducted-slab-derived fluids/melts. Remarkably, these mafic-ultramafic plutons have extremely high 956 ppm, respectively).The coeval quartz diorites have 59.55-64.86 wt% of SiO 2 , 3.02-4.21 wt% of K 2 O and 3.97-4.49 wt% of Na 2 O. They are enriched in light REEs (LREEs) and large-ion lithophile elements (LILEs); depleted in heavy REEs (HREEs) and HFSEs, and they have ε Hf (t) values in the range À6.4 to +2.9. Additionally, the felsic rocks exhibit adakitic-features with high Sr/Y (28.5-58.7) and (La/Yb) N (4.9-12.2) ratios, implying the thickening crustal sources of the North China Craton (NCC) and CAOB, respectively. The above findings, combined with the regional geological data, suggest that the Middle Triassic mafic-ultramafic plutons are the prelude to the large-scale Late Triassic mineralization. This was induced by the thickening event of the later period of Middle Triassic felsic rocks, accompanying the final closure of the Palaeo-Asian Ocean (PAO) in the eastern CAOB.

“…

From the Paleozoic to the Mesozoic, the GXR and adjacent areas experienced tectonic transformation and superposition of the Paleo-Asian Ocean tectonic regime, the Mongol-Okhotsk Ocean (MOO) tectonic regime, and the Paleo-Pacific Ocean (PPO) tectonic regime, accompanied by complex and multiple structures, magmatism, and mineralization (Xu et al, 2013;Wilde, 2015;Wang et al, 2019Wang et al, , 2022. The GXR is one of the essential magmatic-metallogenic belts in northeast China and offers great resource potential (Deng et al, 2019a;Chen et al, 2021).

The southern Great Xing'an Range is the most critical Sn‐polymetallic metallogenic belt in northeast China. However, the tectonic setting of the Early Cretaceous magmatic‐metallogenic “flare‐up” event remains uncertain. This paper presents an integrated study on the occurrence, petrology, zircon U–Pb ages, whole‐rock geochemistry, and in situ zircon Hf isotopes for Wenduerchagan granites of Xi Ujimqin Banner, central‐eastern Inner Mongolia. These granites consist primarily of granite porphyry (with ages of 137 ± 1 Ma and 138 ± 1 Ma) and (porphyritic) alkali feldspar granite (with an age of 141 ± 2 Ma), corresponding to the early Early Cretaceous. They are A‐type granites characterized by high silicon, alkali, and FeOT/MgO contents while being depleted of Ba, Nb, Ta, Sr, P, and Ti. They show right‐dipping trend rare‐earth element distribution characteristics with negative Eu anomalies (Eu/Eu* = 0.01–0.20) and weak heavy rare‐earth element fractionation ((Gd/Yb)N = 0.77–2.30). They demonstrate homogeneous zircon Hf isotopic compositions (positive ɛHf (t) values from +5.3 to +7.1 and young two‐stage Hf model ages of 851–742 Ma) and high zircon saturation temperatures (av. 810 °C). These geochemical characteristics indicate that Wenduerchagan granites originated from the partial melting of juvenile crust under high‐temperature and low‐pressure conditions. Wenduerchagan granites most likely formed in a post‐collisional compression‐extension transition regime caused by the closure of the Mongol‐Okhotsk Ocean, when combined with regional geology. Such a transition regime can probably be attributed to the upwelling of the asthenospheric mantle caused by the break‐off of a subducted Mongol‐Okhotsk oceanic slab. Upwelling asthenospheric mantle provided sufficient energy and favorable tectonic conditions for magmatism and mineralization of the Early Cretaceous.
