“…During the Mesozoic Era, the northeastern Asian continental margin was an active continental margin, characterized by a fore-arc region, island arc and retro-arc foreland basin systems (Zhang et al 2019). Subduction processes were likely responsible for uplift and exhumation of the continental margin, thus controlling drainage systems and the architecture of sedimentary basins (Zhang et al 2015;Zhou et al 2020).…”

The uplift history of northeastern Asian continental margin has been the subject of much debate. The Sanjiang Basin is an ideal area to investigate the uplift history of this margin. We present new data from sandstone petrology, whole-rock geochemistry, U–Pb geochronology and Hf isotopy of detrital zircons to trace the provenance of the basin and to unravel the uplift history of the northeastern Asian continental margin. We investigated the chemical and plagioclase indices of alteration and index of compositional variability (CIA, PIA and ICV, respectively) in samples from two formations. The geochemical proxies indicate that source rocks were subjected to an intensified weathering process. Based on the high SiO2/Al2O3 values and low K2O, we infer that the two basinal strata experienced silicification and insignificant potassium metasomatism. Sandstone petrography is indicative of low degrees of sedimentary sorting, suggesting a proximal deposition. The provenance fingerprints of light rare earth, high-field-strength and transition metal elements indicate that parts of the provenance included recycled sediments, and that first-cycle sediments were derived mainly from felsic rocks with a minor contribution from intermediate and mafic rocks. The combined detrital zircon U–Pb ages and Hf isotopic results constrain the contributions of different source terranes over time. The provenance results, in combination with seismic profile interpretations from the Sanjiang Basin, suggest that the northeastern Asian continental margin experienced at least three stages of uplift, which were driven by subduction initiation of the Paleo-Pacific Ocean during the Jurassic Period, a plate motion change during the Early Cretaceous Epoch, and a shallowing of the slab dip angle during the Late Cretaceous Epoch.

“…Regardless of the origin of the seamount chains, whether the hotspot is fixed or mobile, seamount chains are being carried along by plate motions and are eventually subducted beneath a continental/oceanic plate or accreted in the accretionary complex (e.g., Buchs et al, 2009; Buchs, Hoernle, Hauff, & Baumgartner, 2016; Cloos, 1992; Isozaki, Maruyama, & Fukuoka, 1990; Kerr, Tarney, Nivia, Marriner, & Saunders, 1998; Kerr, White, & Saunders, 2000; Lallemand & Pichon, 1987; Lu et al, 2016; Morton, Bilek, & Rowe, 2018; Park et al, 1999; Singh et al, 2011; Staudigel & Clague, 2010; Tao et al, 2020; von Huene, 2008; Wan et al, 2021; G. X. Yang, Li, Xiao, & Tong, 2015; K. J. Zhang, Yan, & Ji, 2019). Indeed, observations of seamount/oceanic plateau subduction at active margins have been documented around the world (Figure 1), such as the Ontong Java Plateau is colliding with the Solomon Islands (Mann & Taira, 2004; L. L. Wang, Dai, et al, 2022), the Cocos Ridge under Costa Rica (Vannucchi, Fisher, Bier, & Gardner, 2006; von Huene, Ranero, Weinrebe, & Hinz, 2000), the Louisville seamount chain subducted beneath the Tonga–Kermadec arc (Timm et al, 2013), and the Ogasawara Plateau is initially subducting and underplating their respective fore‐arc regions (Miura, Nakamura, Koda, Tokuyama, & Coffin, 2004).…”

“…The CAOB is generally thought to be related to the closure of the Paleo‐Asian Ocean from Early Neoproterozoic to Late Palaeozoic (Dobretsov, Buslov, & Vernikovsky, 2003; Han & Zhao, 2018; Wan, Li, Xiao, & Windley, 2018; Wilhem, Windley, & Stampfli, 2012; Xiao et al, 2009), which involved the accretion of various terrains (island arcs, accretionary prisms, seamounts, oceanic plateaus, ophiolitic mélanges, and microcontinents) to the southern margin of the Siberian Craton (Buslov et al, 2001; Buslov, Fujiwara, Iwata, & Semakov, 2004; Wan et al, 2021; Windley et al, 2007; Xiao et al, 2010; Xiao & Santosh, 2014; Xiao, Windley, Allen, & Han, 2013; G.

The effect of seamount chain subduction and accretion

Seamount chains (oceanic plateaus, submarine ridges) are unique morphologic features on the seafloor, which resulted from the motion of the lithosphere over a convective plume. Seamount chains are being carried along by plate motions, which are eventually subducted beneath continental/oceanic plates or accreted in the accretionary complex, thus causing a series of effects in the convergent margin. In this paper, we briefly review the distribution and features of the typical modern seamount chains, including Hawaiian‐Emperor and Louisville seamount chains, Cocos, Ninetyeast and Caroline ridges, and Ogasawara Plateau, and mainly focus on the effects of seamount chains subduction and accretion. The geological effects mainly include the following: (1) deformation and tectonic erosion of the overriding plate; (2) flat‐slab subduction in the convergent margin; (3) growth of continental crust through time; (4) subduction initiation of plate tectonics; (5) generation of large earthquakes; (6) magmatism of the volcanic arc; and (7) formation of porphyry copper and gold deposits. The subduction of seamount chains resulted in similar effects in the Central Asian Orogenic Belt (CAOB) which is one of the largest and longest‐lived accretionary orogens on Earth. However, there are still many aspects that need further improvements, such as identification of the seamounts in the geological record, and geodynamic effects of subducted seamount chains. A detailed study on these sides of the seamount chains will enable us to further understand the tectonic evolution and metallogenesis of the CAOB, especially in accretionary orogenesis, continental crust growth, and subduction initiation dynamics.

The Inner Mongolia Plateau is located in the north of the Late Palaeozoic Hegenshan ophiolitic mélange belt, and its Mesozoic magmatism impacts our understanding of the tectonic evolution affected by the closing of the Mongol-Okhotsk Ocean and Palaeo-Pacific Ocean. Here, we present new U-Pb ages, whole-rock geochemistry and Hf isotopes from the Late Mesozoic magmatic rocks in the Dalai area along the northeastern margin of the Inner Mongolia Plateau. The Late Jurassic rock types include medium-fine-grained phenocryst-bearing and porphyritic monzogranites as well as medium-fine-grained monzogranites with the precise age range of 167.7-159.8 Ma. The Early Cretaceous rock types consist of fine-grained biotite monzogranite and medium-fine-grained biotite monzogranite with the precise age range of 140.9-130.7 Ma. The geochemistry data show that the Late Jurassic and Early Cretaceous rocks are peraluminous granites and high-K calc-alkaline series and can be classified as A-type granite. These granites are enriched in large-ionlithophile elements such as Rb, Th and U, depleted in the highfield-strength elements such as Nb, Sr, P, and Ti. Rare earth elements have high total concentrations and present the light rare earth elements enriched with the heavy rare earth elements depleted. Zircon Hf isotopes show that εHf(t) ranges from +8.0 to +15.9 from the Late Jurassic rocks and +6.9 to +13.5 from the Early Cretaceous rocks. Our new results reveal that the Late Jurassic and the Early Cretaceous magmas were derived from partial melting of the younger lower crust, and the Early Cretaceous rocks are more strongly contaminated than the Jurassic intrusions. The Late Jurassic rocks in the Dalai area were formed from a post-collisional setting related to the closure of the Mongol-Okhotsk Ocean in the Early-Middle Jurassic. The Early Cretaceous intrusions were formed from a transition setting from post-collision to syn-collision associated with the superposition of the Mongol-Okhotsk Ocean and the Palaeo-Pacific Ocean tectonic domain.
