“…Basin development was associated with important magmatic activity . Furthermore, several extensional metamorphic core complexes have been documented in Transbaikalia, northern Mongolia and northern China (Sklyarov et al 1994;Davis et al 1996Davis et al , 2002Zheng et al 1996;Webb et al 1999;Darby 2003;Darby et al 2004;Liu et al 2005;Mazukabzov et al 2006;Donskaya et al 2008). On the other hand, numerous outcrops of basement in eastern Mongolia and surrounding areas have been mapped as pre-Palaeozoic to Palaeozoic in age (Yanshin 1983) on the basis of their intense deformations and high metamorphic grade (see discussions in Mazukabzov et al (2006) and Donskaya et al (2008) for Transbaikalia).…”

“…However, since the last decade, numerous outcrops of high-grade metamorphic basement have been interpreted in terms of metamorphic core complexes in Transbaikalia, northern Mongolia and north-eastern China (Sklyarov et al 1994;Davis et al 1996Davis et al , 2002Zheng et al 1996;Webb et al 1999;Darby et al 2004;Liu et al 2005;Mazukabzov et al 2006;Donskaya et al 2008). Interpretations involve deep crust exhumation during Mesozoic extensive tectonics that followed compression related to the Central Asian Orogenic Belt (Mazukabzov et al 2006;Donskaya et al 2008).…”

International audienceMesozoic rift basins locally bounding metamorphic core complexes have been recognized in Transbaikalia and northern China. Numerous basement outcrops located between these two regions, in eastern Mongolia, are considered as pre-Palaeozoic in age. One of these, the Ereendavaa Range, appears as a gneissic core marked by amphibolite-facies metamorphic conditions. The range is overlain to the NW by the unmetamorphosed Mesozoic Onon Basin. Below the basin, the upper part of the range consists of a gently NW-dipping shear zone associated with top-to-the-NW motion. The structural pattern is consistent with syn-extensional exhumation of the range. Preliminary geochronological data indicate that the shear zone is late Jurassic to early Cretaceous in age, coeval with the Onon Basin. These new data from eastern Mongolia constitute a link between Transbaikalia and northern China, indicating that NW-SE extensional Mesozoic tectonics occurred throughout the entire region

“…1b; Liu et al, 2013). Detailed studies on the coexistence of Cretaceous volcanic-sedimentary basins, low-angle normal faults, exhumed high-grade metamorphic rocks with early Cretaceous cooling ages, and widespread A-type granitoids in the lower plate of the MCC demonstrate that the crust of the Liaodong Peninsula was relatively thin and experienced exceptionally intense extension during early Cretaceous times (Liu et al, 2005. Therefore, no thickened lower crust is likely to have been present in the study area at that time; correspondingly, the melting of lower continental crust probably occurred at depths <40 km.…”

Coexisting Early Cretaceous High-Mg Andesites and Adakitic Rocks in the North China Craton: the Role of Water in Intraplate Magmatism and Cratonic Destruction

High-Mg andesites (HMAs) and adakitic rocks are purported to occur exclusively in subduction zones in the modern Earth. In the North China Craton, early Cretaceous HMAs and adakitic dacites were erupted in a continental setting, apparently unrelated to subduction given their location distal (>1000 km) to the trench at that time. Here we report petrological, mineralogical and geochemical data for these rocks with the aim of constraining their petrogenesis and elucidating the role of water in intraplate magmatism and cratonic destruction. The HMAs can be subdivided into olivine (Ol-)HMAs and clinopyroxene (Cpx-)HMAs. The former have high MgO (>9Á8 wt %) and Mg# (>71), with rare high-Fo (up to 91) olivine phenocrysts, corresponding to (near-)primary magmas that equilibrated with mantle peridotite. The latter have moderate MgO (7Á8-8Á8 wt %) and Mg# (mostly <70) and low-Fo (mostly < 83) olivine phenocrysts. The Cpx-HMAs are interpreted as magmas differentiated from the Ol-HMAs by olivine-dominated fractionation at lower-crust levels. P-T-X H2O estimations show that the primary HMAs are melts of shallow (1Á1-1Á2 GPa), hot ($1250 C) and wet (H 2 O > 3 wt %) lithospheric mantle. The coexisting adakitic dacites are hydrous (H 2 O ! 5 wt %) magmas with high SiO 2 (>63 wt %), Sr/Y ratios (!39) and Yb SN (source-normalized), low (Sm/Yb) SN , and negligible Eu anomalies. They also have unradiogenic whole-rock Nd [e Nd (t) ¼ -19 to -9] and zircon Hf [e Hf (t) ¼ -23 to -21] isotopic compositions consistent with derivation by melting of ancient lower crust at depths < 40 km. Melting may have been induced by heating and addition of H 2 O from underplated HMAs. Mixing between Cpx-HMAs and low-Mg adakitic dacites in magma chambers produced high-Mg adakitic rocks. The petrogenetic model presented here explains the occurrence of intraplate HMAs and adakitic magmas elsewhere in the North China Craton. The P-T-X H2O conditions inferred for HMA generation imply that the subcontinental lithospheric mantle beneath the craton was hot and hydrous in the early Cretaceous, which may have triggered the destruction of the cratonic root. The occurrence of young HMAs and adakitic rocks in an intraplate extensional environment also casts doubts on the common use of a similar igneous rock association as an indicator of subduction processes in Archean time.

Multiple Emplacement and Exhumation History of the Late Mesozoic Dayunshan–Mufushan Batholith in Southeast China and Its Tectonic Significance: 1. Structural Analysis and Geochronological Constraints

The South China Block (SCB) experienced a polyphase reworking by the Phanerozoic tectonothermal events. To better understand its Late Mesozoic tectonics, an integrated multidisciplinary investigation has been conducted on the Dayunshan–Mufushan composite batholith in the north‐central SCB. This batholith consists of two major intrusions that recorded distinct emplacement features. According to our structural analysis, two deformation events in relation to batholith emplacement and subsequent exhumation are identified. The early one (D1) was observed mostly at the southern border of the batholith, characterized by a top‐to‐the‐SW ductile shearing in the early‐stage intrusion and along its contact zone. This deformation, chiefly associated with the pluton emplacement at ca. 150 Ma, was probably assisted by farfield compression from the northern Yangtze foreland belt. The second but main event (D2) involved two phases: (1) ductile shearing (D2a) prominently expressed along the Dayunshan detachment fault at the western border of the batholith where the syntectonic late‐stage intrusion and minor metasedimentary basement in the footwall suffered mylonitization with top‐to‐the‐NW kinematics; and (2) subsequent brittle faulting (D2b) further exhumed the entire batholith that behaved as rift shoulder with half‐graben basins developed on its both sides. Geochronological constraints show that the crustal ductile extension occurred during 132–95 Ma. Such a Cretaceous NW–SE extensional tectonic regime, as indicated by the D2 event, has been recognized in a vast area of East Asia. This tectonism was responsible not only for the destruction of the North China craton but also for the formation of the so‐called “southeast China basin and range tectonics.”
