“…In contrast, recent studies show that the majority of the dated volcanic rocks erupted in the Early Cretaceous, with the basal Manketouebo formation erupted in the Late Jurassic (Zhang et al, 2010 and references therein). Recently high precise age data show large range in crystallization age for the four volcanic formations, indicating that the subdivision and correlation of these volcanic strata needs to be re-evaluated (Wang et al, 2006;Ying et al, 2010;Zhang et al, 2010). According to our data and compilation in Fig.…”

“…The widespread Mesozoic volcanic rocks in the GXM were documented by numerous previous works (e.g., Wang et al, 2006;Zhang et al, 2008aZhang et al, , 2010Ying et al, 2010;Wu et al, 2011). In the southern GXM, the large-scale volcanisms in the Late Mesozoic were re-evaluated based on the systematic and high precision isotopic ages (Ying et al, 2010;Zhang et al, 2010).…”

“…The volcanic rocks in the southern GXM are mainly distributed in several discrete basins, including the Baoshi, Pingshan and Wudan basins, and have been subdivided into the Manketouebo, Manitu, Baiyingaolao and Meiletu formations (Fig. 2;IMBGMR, 1991;Ying et al, 2010;Zhang et al, 2010). The Manketouebo formation is widely distributed and mainly composed of rhyolite, dacite, volcaniclastic rock and rhyolitic tuff.…”

“…In the southern GXM, the large-scale volcanisms in the Late Mesozoic were re-evaluated based on the systematic and high precision isotopic ages (Ying et al, 2010;Zhang et al, 2010).

“…In the Great Xing'an area, the Mesozoic volcanic rocks cover an area of ca. 100,000 km 2 (Ying et al, 2010), and mainly distribute along the GXM. Numerous geological, petrological and geochronological studies were carried out on these large-scale magmatic activities (Jahn et al, 2001;Fan et al, 2003;Wu et al, 2005;Wang et al, 2006;Zhang et al, 2008aZhang et al, , 2008bZhang et al, , 2010Guo et al, 2010;Yang et al, 2013), which have not resulted in a consensus about the mechanism.…”

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.

The Role of Recycled Oceanic Crust in the Generation of Alkaline A‐Type Granites

Melting and dehydration of subducted oceanic slabs dominate element recycling within the subduction factory, but the role of recycled oceanic crust in the source of intraplate magmas is poorly understood. In situ zircon O‐Hf isotope data from two Early Cretaceous alkaline A‐type granites that are genetically related to large‐scale extension of eastern China in the Late Mesozoic (circa 125 Ma) yield low δ18O (1.8 ± 0.3‰ to 5.1 ± 0.3‰, 2σ) and positive εHf(t) (1.5 ± 1.2 to 17 ± 1.2, 2σ). This suggests the contribution of altered oceanic crust and an enriched mantle component in the source region. Elevated initial 87Sr/86Sr and 206Pb/204Pb ratios, and εHf(t) whole rock values with relatively constant εNd(t) values beyond the normal mantle array, require a component that underwent seawater interaction in the source of protolith. The geochemical data require a complex source region for the alkaline A‐type granites in NE China involving more than 40% recycled oceanic crust. This altered oceanic crust beneath the Late Mesozoic lithospheric mantle likely represents remnants of multiple subduction and collision events between microblocks from the Late Paleozoic to Early Mesozoic in northeastern China. Recycling of subducted oceanic crust represents a novel exotic source for the origin of alkaline A‐type granites in intraplate extensional settings.
