“…We have shown that early Mesozoic magmatism in central southern Jilin Province can be identified based on three stages: Middle Triassic (~246 Ma), Late Triassic (~219–220 Ma), and Early Jurassic (~172–194 Ma). The occurrence of these events is supported by previous and independent studies throughout the NE China as well as the NCC northern margin (Tang et al, , and reference therein; Wu et al, ; Xu, Pie, et al, ; Xu, Wang, et al, ; Zhang et al, , and reference therein).…”

“…Early–Middle Triassic igneous rocks are widespread within the eastern end of the NCC northern margin and include mafic to felsic volcanic and intrusive rocks (Cao et al, ; Li et al, ; Wang, Xu, et al, ; Yang et al, ; Zhang et al, , , ) that form an E–W trending belt (Tang et al, ; Zhang et al, ). In contrast, only minor Early–Middle Triassic granitoids occur along the eastern segment of the CAOB, mainly distributed in Yanbian Area (Tang et al, , and references therein; Wu et al, , and references therein; Yang et al, ; Yang, Wu, Liu, et al, ; Yang, Wu, Wilde, et al, ; Zhang et al, , and references therein). A Late Triassic magmatic event is supported by abundant Late Triassic igneous rocks in eastern NE China (Tang et al, ; Wu et al, ; Xu, Pei, et al, ; Xu, Wang, et al, , and references therein) as well as the Middle–Late Triassic granitoids and alkaline complexes along the northern margin of the NCC (Cao et al, ; Wu et al, ; Yang et al, ; Zhang et al, ).…”

“…Similarly, Early Jurassic magmatic event in central Jilin Province are supported by the other studies that reported widespread Early Jurassic igneous rocks throughout the eastern NE China as well as the in Korean Peninsula (Kim et al, , and references therein; Liu, Zhang, et al, ; Tang et al, , and references therein; Wu, Han, et al, , Wu et al, ; Xu, Pei, et al, ; Xu, Wang, et al, ; Zhang et al, , and references therein). In addition, Early Jurassic igneous rocks occur within the NCC, mainly in the Yanshan belt (Zhang et al, , and references therein) and, to a lesser extent, in northeastern Liaoning Province (Wu et al, ; Yang, Wu, Liu, et al, ).…”

“…NE China represents the eastern section of the Central Asian Orogenic Belt as well as the eastern margin of Eurasia (Figure a). This region records not only the final closure of the Paleo‐Asian Ocean but also the subduction of the Paleo‐Pacific Plate beneath Eurasia in Late Paleozoic–early Mesozoic (Xiao et al, ; Wilde, , and references therein; Liu, Liu, et al, ; Ryu & Lee, ; Tang et al, ).…”

When the Paleo‐Asian Ocean closed and the Paleo‐Pacific subduction started in NE China remains controversial. To constrain these key issues, we carried out zircon U‐Pb‐Hf isotopic and whole‐rock geochemical studies of Early Mesozoic igneous rocks in central southern Jilin Province, NE China. Early Mesozoic igneous rocks in region were formed at three stages: the middle Triassic (246 Ma), the late Triassic (219–220 Ma), and the early Jurassic (172–194 Ma). Middle Triassic trachyandesites in southern Jilin Province were solely generated through partial melting of ancient lower crust of the North China Craton (NCC), implying ongoing southward subduction of Paleo‐Asian Ocean Plate beneath the NCC at this time. Late Triassic trachyandesites in southern Jilin Province were derived from the magma mixing/mingling of the NCC lithospheric mantle and juvenile eastern Central Asian Orogenic Belt crustal sources. Late Triassic hornblende gabbros in central Jilin Province were derived from depleted lithospheric mantle previously metasomatized by subduction‐related fluids. Coeval adakitic granodiorites were likely produced through the partial melting of thickened juvenile lower crust. Spatially, these rocks occurred on both sides of the Solonker‐Xra‐Moron‐Changchun Suture Zone and record N–S directed extension accompanied by the final closure of the Paleo‐Asian Ocean. Early Jurassic andesites were produced through mixing/mingling between partial melts derived from eastern Central Asian Orogenic Belt lithospheric mantle and ancient NCC crust. In contrast, Early Jurassic felsic rocks, including A‐type granites, were derived from the partial melting of Neoproterozoic accreted lower crust, jointly implying an extensional setting as the result of the initial subduction from Paleo‐Pacific Plate at this time.

Timing and evolution of Mesozoic volcanism in the central Great Xing'an Range, northeastern China

et al. 2018

In this paper, we report on LA‐ICP‐MS zircon U–Pb dates of 14 Mesozoic volcanic rocks from the central Great Xing'an Range (CGXR). These data are integrated with the temporal and spatial distribution of local magmatism‐related Mesozoic mineralization, in an effort to develop an understanding of the geodynamic evolution of the region. Periodic magmatic events in the GXR date from ~1,703 through ~145 Ma. Mesozoic volcanism in the CGXR can be subdivided into three episodes: Triassic (250–205 Ma), Early–Middle Jurassic (182–165 Ma), and Late Jurassic–Early Cretaceous (155–115 Ma). A revision of the previously defined volcanic sequence is offered using a combination of our zircon U–Pb ages and published Mesozoic geological and geophysical evidence from northeast China. We propose that (a) Early–Middle Triassic volcanism in the CGXR resulted from subduction of the Paleo‐Asian oceanic plate; (b) Late Triassic volcanism was related to subduction of the Mongol–Okhotsk oceanic plate (especially near the Erguna Block) and subsequent extension after the closure of the Paleo‐Asian Ocean; (c) Early–Middle Jurassic volcanism was mainly controlled by the southward subduction of the Mongol–Okhotsk oceanic plate; (d) Late Jurassic–initial Early Cretaceous magmatism was initiated by closure of the Mongol–Okhotsk Ocean; and (e) late Early Cretaceous volcanism was induced following the final closure of the Mongol–Okhotsk Ocean and rollback of the Paleo‐Pacific oceanic plate.

In this study, we present new U–Pb zircon ages and whole‐rock major and trace element data for the late Carboniferous–Middle Jurassic intrusive rocks in the Helong area, NE China. These data constrain the timing of tectonic transition from the Paleo‐Asian oceanic regime to the circum‐Pacific regime. U–Pb zircon dating indicates that the late Carboniferous–Middle Jurassic magmatic events in the Helong area can be subdivided into late Carboniferous, middle Permian, Early–Middle Triassic, Late Triassic, Early Jurassic, and early Middle Jurassic. The late Carboniferous granodiorites and middle Permian monzogranites belong to the calc‐alkaline series and have an affinity to I‐type granitoids, suggesting that they formed in a typical Andean‐type continental arc setting due to the southward subduction of the Paleo‐Asian oceanic plate beneath the NCC. The Middle Triassic granodiorites and monzogranites in the Helong area exhibit an affinity to adakitic rocks with their parental magma derived by the partial melting of thickened lower continental crust. The Late Triassic I‐type monzogranites and coeval ultramafic–mafic rocks constitute a bimodal igneous rock association, together with coeval A‐type granites and rhyolites, signifying an extensional environment. Combined with the absence of 240‐ to 225‐Ma sedimentation, the study area experienced a change from Early–Middle Triassic compression to Late Triassic extension related to the final closure of the Paleo‐Asian Ocean. The Early–early Middle Jurassic gabbros, diorites, granodiorites, and monzogranites are calc‐alkaline in nature and enriched in LREE and LILE but depleted in HREE and HFSE. Combined with the spatial variations in K contents of Early Jurassic igneous rocks in NE China from the continental margin to intracontinental region, and the presence of an Early Jurassic accretionary complex, we suggest that Early–early Middle Jurassic magmatism in the Helong area formed in an active continental margin setting related to the subduction of the Paleo‐Pacific Plate beneath Eurasia. We conclude that the tectonic transition from the Paleo‐Asian oceanic regime to the circum‐Pacific regime occurred in the Late Triassic–Early Jurassic.
