“…Others argue that the Russian Far East and NE China were geologically active continental margin related to the subduction of the paleo-Pacific plate during 130-100 Ma (Faure and Natal'in, 1992;Kiminami and Imaoka, 2013;Sun et al, 2013;Wu et al, 2011;Xu et al, 2013). The exact position of the plate boundary, whether subduction or transform, is unknown.…”

“…Age of the complexes tends to be younger toward southeast to the youngest Kiselevka-Manona complex of Albian-Cenomanian age (Zyabrev, 1996;Markevich et al, 1997). To the southeast of these complexes again, Jurassic to Early Cretaceous accretionary terrane of the Sikhote-Alin belt lies with a boundary named Amur Suture (Natal'in and Zyabrev, 1989;Faure and Natal'in, 1992). Although detailed stratigraphic study has been made only in limited areas because of poor exposure and hard access, available biostratigraphic data are presented below and in Figure 4 because they are essential for tectonic discussion.…”

Age of magmatism and tin mineralization in the Khingan-Okhotsk volcano-plutonic belt, including the Khingan, Badzhal and Komsomolsk tin fields, were reviewed in terms of tectonic history of the continental margin of East Asia. This belt consists mainly of felsic volcanic rocks and granitoids of the reduced type, being free of remarkable geomagnetic anomaly, in contrast with the northern Sikhote-Alin volcano-plutonic belt dominated by oxidized-type rocks and gold mineralization. The northern end of the Khingan-Okhotsk belt near the Sea of Okhotsk, accompanied by positive geomagnetic anomalies, may have been overprinted by magmatism of the Sikhote-Alin belt.Tin-associated magmatism in the Khingan-Okhotsk belt extending over 400 km occurred episodically in a short period (95±10 Ma) in the middle Cretaceous time, which is coeval with the accretion of the Kiselevka-Manoma complex, the youngest accretionary wedge in the eastern margin of the Khingan-Okhotsk accretionary terranes. The episodic magmatism is in contrast with the Cretaceous-Paleogene long-lasted magmatism in Sikhote-Alin, indicating the two belts are essentially different arcs, rather than juxtaposed arcs derived from a single arc. The tin-associated magmatism may have been caused by the subduction of a young and hot back-arc basin, which is inferred from oceanic plate stratigraphy of the coeval accretionary complex and its heavy mineral assemblage of immature volcanic arc provenance. The subduction of the young basin may have resulted in dominance of the reduced-type felsic magmas due to incorporation of carbonaceous sediments within the accretionary complex near the trench. Subsequently, the back-arc basin may have been closed by the oblique collision of the accretionary terranes in Sikhote-Alin, which was subjected to the Late Cretaceous to Paleogene magmatism related to another younger subduction system. These processes could have proceeded under transpressional tectonic regime due to oblique subduction of the paleo-Pacific plates under Eurasian continent.

“…Evidence from the motion trait of the Pacific Oceanic plate showed that the NE Asian continental margin had interacted with the Pacific slab at least since late Mesozoic [13,14]. In both the Junan and Qingdao regions, there also exist high-MgO peridotite xenoliths that represented the old and refractory lithospheric mantle beneath the NCB [10,12].…”

“…Previous studies considered that the newly-accreted MORB-type mantle was formed through melting and thermal decay of the convective asthenosphere or melt-peridotite interaction in an extensional regime. Nevertheless, subduction of the Pacific oceanic slab beneath the Asian continent might also be a potential cause to modify the lithospheric mantle beneath the NCB since this subduction event occurred at least before the middle to late Cretaceous [13][14][15]. Also, geochemical studies on Cenozoic basalts in the eastern NCB indicate that the melting sources for these mafic lavas contained the component of the recycled Pacific oceanic crust [16][17][18][19].…”

The North China Block (NCB) experienced extensive lithospheric thinning and subsequent mantle accretion in the Mesozoic to Cenozoic, but their mechanism remains controversial. This paper reports in situ chemical and oxygen isotope analyses on olivine xenocrysts and porphyroclastic olivines in mantle xenoliths hosted in the late Cretaceous basalts from Junan and Qingdao, the Sulu orogen. The results show that all these olivines have low  18 O values relative to normal mantle peridotite. The olivine xenocrysts and porphyroclastic olivines from Junan have Fo=87.589.8,  18 O=4.1‰-5.2‰ with an average of 4.8‰; the porphyroclastic olivines from Qingdao also have Fo=89.089.9,  18 O=4.1‰-5.2‰ with an average of 4.8‰. These peridotite xenoliths have petrological and geochemical affinities similar to newly accreted MORB-type mantle, we hence consider such low- 18 O features in the olivines to inherit from a mantle wedge that was metasomatized by melts derived from the subducted oceanic crust, which had experienced high-temperature hydrothermal alteration to acquire the low- 18 O signatures. Combined the existence of Cenozoic low- 18 O basalts and garnet pyroxenite xenoliths (relicts of recycled oceanic crust) hosted in Cenozoic basalts in the NCB, the subducted oceanic crust likely played an important role in the lithospheric evolution of the NCB during the Mesozoic to Cenozoic.
