TL;DR: Zhang et al. as mentioned in this paper used zircon U-Pb dating to constrain the spatial and temporal distribution of granitoids in the area. But the results showed that granitoid emplacement dates are not as widely distributed as previously thought.
1,239 citations
TL;DR: In this article, the authors present partial results of a series of studies on the granitoids from this region, aiming to understand their role in the building of new continental crust in eastern Asia.
543 citations
TL;DR: In this article, the ages of 43 volcanic rocks from the four recognized formations (Manketouebo, Manitu, Baiyingaolao and Meiletu) in the southern Great Xing'an Range are presented.
398 citations
TL;DR: In this paper, the authors used geochemical and isotope data of three granitic plutons (Xinhuatun, Lamashan and Yiershi) to determine the proportion of mantle to crustal components in the generation of the voluminous granitoids.
351 citations
TL;DR: Zhang et al. as discussed by the authors conducted a systematic dating of volcanic rocks in the Great Xing'an Range in order to rectify the limited precise age data for the volcanic rocks, which significantly hinders understanding of the petrogenesis and geodynamic setting of these rocks.

TL;DR: In this paper, the authors proposed a model for the evolution of the North China Craton that envisages discrete Eastern and Western Blocks that developed independently during the Archean and collided along the Trans-North China Orogen during a Paleoproterozoic orogenic event.

TL;DR: In this article, Zhang et al. used zircon U-Pb SHRIMP (5 samples), laser ablation (LA) ICP-MS (22 samples), and TIMS (5 sample) dating to establish that the Early Cretaceous was a significant period of igneous activity in the Liaodong Peninsula, with a duration of about 10 Ma.

TL;DR: Using the Nd-Sr isotope tracer technique, the majority of granitoids from the Central Asian Orogenic Belt (CAOB) can be shown to contain high proportions (60 to 100%) of the mantle component in their generation as discussed by the authors.
Abstract: Abstract Asia is the world’s largest composite continent, comprising numerous old cratonic blocks and young mobile belts. During the Phanerozoic it was enlarged by successive accretion of dispersed Gondwana-derived terranes. The opening and closing of palaeo-oceans would have inevitably produced a certain amount of fresh mantle-derived juvenile crust. The Central Asian Orogenic Belt (CAOB), otherwise known as the Altaid tectonic collage, is now celebrated for its accretionary tectonics and massive juvenile crustal production in the Phanerozoic. It is composed of a variety of tectonic units, including Precambrian microcontinental blocks, ancient island arcs, ocean island, accretionary complexes, ophiolites and passive continental margins. Yet, the most outstanding feature is the vast expanse of granitic intrusions and their volcanic equivalents. Since granitoids are generated in lower-to-middle crustal conditions, they are used to probe the nature of their crustal sources, and to evaluate the relative contribution of juvenile v. recycled crust in the orogenic belts. Using the Nd-Sr isotope tracer technique, the majority of granitoids from the CAOB can be shown to contain high proportions (60 to 100%) of the mantle component in their generation. This implies an important crustal growth in continental scale during the period of 500–100 Ma. The evolution of the CAOB undoubtedly involved both lateral and vertical accretion of juvenile material. The lateral accretion implies stacking of arc complexes, accompanied by amalgamation of old microcontinental blocks. Parts of the accreted arc assemblages were later converted into granitoids via underplating of basaltic magmas. The emplacement of large volumes of post-accretionary alkaline and peralkaline granites was most likely achieved by vertical accretion through a series of processes, including underplating of basaltic magma, mixing of basaltic liquid with lower-crustal rocks, partial melting of the mixed lithologies leading to generation of granitic liquids, and followed by fractional crystallization. The recognition of vast juvenile terranes in the Canadian Cordillera, the western US, the Appalachians and the Central Asian Orogenic Belt has considerably changed our view on the growth rate of the continental crust in the Phanerozoic.

TL;DR: In this paper, the authors used the ICP-MS zircon U-Pb ages and geochemical data for the Mesozoic volcanic rocks in northeast China, with the aim of determining the tectonic settings of the volcanism and constraining the timing of the overprinting and transformations between the Paleo-Asian Ocean, Mongol-Okhotsk, and circum-Pacific Tectonic regimes.
