“…The comprehensive new age data from the ophiolites, magmatic and metamorphic rocks and sedimentary records in the southeastern CAOB support the ultimate closure of the paleo-Asian Ocean at least by the end of Permian (Zhou and Wilde, 2013;Eizenhöfer et al, 2014;Wilde, 2015;Song et al, 2015). The similarities (e.g., the water-saturated primary magmas and arc-type trace elemental and Sr-Nd-Hf isotopic compositions) between the Yanbian Permian mafic intrusions and the mafic cumulates in modern subduction zones also indicate that they were associated with the subduction of the paleo-Asian Ocean.…”

“…3d), reflecting a late Permian emplacement age for the pluton. In summary, the mafic intrusions from the Yanbian area were formed during 273-254 Ma, when the paleo-Asian Ocean was subducted toward the North China Craton (Dobretsov et al, 1995;Xiao et al, 2003Xiao et al, , 2015Li, 2006;Wilde, 2015).…”

“…Several hypotheses, including the middle Devonian (e.g., Xu et al, 2013a), between the late Devonian and early Carboniferous (e.g., Tang, 1990), or even in the late Permian to Triassic (e.g., Zhou and Wilde, 2013;Eizenhöfer et al, 2014;Wilde, 2015), have been proposed. In NE China, especially in the central Mongolia, the Permian mafic rocks show geochemical and isotopic features of N-MORBs and E-MORBs, reflecting the existence of oceanic basin at that time (Chen et al, 2012;Li et al, 2015).…”

“…Zhou and Wilde (2013) carried out a comprehensive review of the late Permian and Triassic metamorphic rocks and related igneous rocks along the Solonker-Xar Moon-Changchun-Yanji suture, and concluded that the ultimate collision between the North China Craton and the combined NE China microblocks occurred in the middle Triassic. Wilde (2015) summarized that the paleo-Asian Ocean in NE China was closed along this suture by the end of late Permian, although associated magmatic activity continued into the Triassic. Recently, Song et al (2015) compiled the age and geochemical data of the ophiolites from the Hinggan-Inner Mongolian accretionary belt, and proposed that subduction of the 'Young paleo-Asian Ocean' could last into early Triassic (ca.…”

This study presents new geochronological and geochemical data for early Paleozoic igneous rocks of the Zhangguangcai Range, northeastern China, and uses these data to further define the early Paleozoic tectonic evolution of the Songnen-Zhangguangcai Range block (SZB) and the Jiamusi block, and provide insights into crustal growth and reworking processes in these blocks of the eastern Central Asian Orogenic Belt. New zircon U-Pb data indicate widespread early Paleozoic magmatism (ca. 516, and 426 Ma) in the southeastern SZB. The ca. 516 Ma magmatism formed Na-rich tonalites that contain low concentrations of rare earth elements, are enriched in Eu and Sr, have high CaO/Al 2 O 3 and Ba/La ratios, low Rb/Sr and Rb/Ba ratios, and negative Ce anomalies and zircon ε Hf (t) values. These features suggest an origin from magmas generated by partial melting of ancient accumulated gabbroic rocks with the addition of subducted-sediment-derived fluids. The ca. 496-482 Ma magmatism formed calc-alkaline I-type biotite granodiorites and monzogranites, whereas the ca. 475-461 Ma igneous rocks include biotite monzogranites with K-rich adakitic signatures and alkali-feldspar granites. These ca. 496-461 Ma granitoids have zircon ε Hf (t) values from -0.82 to +5.44 and two-stage depleted-mantle model (T DM2 ) ages of 1490-1103 Ma, suggesting they formed from magmas generated by partial melting of heterogeneous Mesoproterozoic lower crustal material. The ca. 426 Ma Na-rich tonalites are geochemically similar to the ca. 516 Ma tonalites and also originated by partial melting of ancient gabbroic or amphibolitic rocks with the involvement of subducted-sediment-derived fluids. The geochemistry of these early Paleozoic igneous rock assemblages is indicative of formation in an active continental margin setting associated with northwestward subduction beneath the southeastern SZB. The zircon Hf isotopic compositions of these early Paleozoic igneous rocks indicate that Paleoproterozoic-Mesoproterozoic crustal material was reworked during the early Paleozoic subduction-and collision-related tectonism.

The origin and geodynamic evolution of peak Early Cretaceous magmatism in the southern Great Xing'an Range, North China, have long been controversial. Here we report new U‐Pb zircon ages (141–129 Ma) of a suite of dioritic‐granitic rocks from central Inner Mongolia, far from the sutures or plate boundaries of the Paleo‐Pacific and Mongol‐Okhotsk oceans, thus delineating an Early Cretaceous intracontinental magmatic province, which had a peak activity at 130–120 Ma. Dioritic suite including diorite, tonalite, and granodiorite shows variable zircon εHf(t) of +1.4 to + 11.8 and δ18O values of +5.7 to +6.9‰, while granitic suite consisting of monzogranite, syenogranite, and granite porphyry also records variable zircon εHf(t) of −0.9 to +15.0 and δ18O values of +6.3 to +8.1‰, suggesting crustal melting by preexisting crustal source with important recycled supracrustal components including fluids. Furthermore, these rocks show variable whole‐rock δ7Li values (−0.6 to +12.1‰), indicating fluids played an important role in magma source. We propose a deep‐sourced water‐fluxed melting scenario by ancient hydrous slabs inherited from the Paleo‐Asian Ocean that were trapped in the deep interior, thus releasing aqueous fluids to melt the lithospheric mantle and produce water‐rich mafic magmas. These mafic magmas were underplated into crust where they promoted water‐fluxed partial melting to generate the large‐scale Early Cretaceous magmatism in the southern Great Xing'an Range. Such melting due to fluxing of aqueous fluids was probably operating as a widespread process responsible for the Early Cretaceous dramatically tectonomagmatic events and evolution of continental crust in NE Asia.
