“…These changes in subduction represent an external factor and the dynamic background for the destruction of the NCC. The internal factor for the destruction of the NCC was the exchange of material and energy between the deep and shallow levels (Zheng & Dai, 2018). In addition to magmatic activity, the timing of ductile extensional metamorphic core complexes in North China tends to become younger from northwest to southeast (Wang et al, 2012).…”

The North China craton (NCC) was dominated by tectonic extension from late Cretaceous to Cenozoic, yet seismic studies on the relationship between crust extension and lithospheric mantle deformation are scarce. Here we present a three dimensional radially anisotropic model of NCC derived from wave-equation traveltime tomography to address this issue. We find a prominent low S-wave velocity anomaly at lithospheric mantle depths beneath the Taihang Mountains, which extends eastward with a gradually decreasing amplitude. The horizontally elongated low-velocity anomaly is also featured by a distinctive positive radial anisotropy (VSH>VSV). Combining geodetic and other seismic measurements, we speculate the presence of a horizontal mantle flow beneath central and eastern NCC, which led to the extension of the overlying crust. We suggest that the rollback of Western Pacific slab likely played a pivotal role in generating the horizontal mantle flow at lithospheric depth beneath the central and eastern NCC.

“…The southeastern YE Basin is controlled by the northwestward subduction of the western Pacific Plate (Chen, 1994; Niu, 2014; Zheng & Dai, 2018), with the stagnant Paleo‐Pacific slab remaining at 400–600 km depth (Figure 11) (Zheng & Dai, 2018), causing upwelling and northward migration of the basin. The northern YE Basin is controlled by the southward movement of the Siberian Craton (Chen, 1994), which blocks the northward movement of the YE Basin (Figure 11).…”

The Chagan Depression in the Yingen-Ejinaqi Basin, located at the intersection of the Paleo-Asian Ocean and the Tethys Ocean domains is an important region to gain insights on terrestrial heat flow, lithospheric thermal structure and deep geodynamic processes. Here, we compute terrestrial heat flow values in the Chagan Depression using a large set of system steady-state temperature data from four representative wells and rock thermal conductivity. We also estimate the "thermal" lithospheric thickness, mantle heat flow, ratio of mantle heat flow to surface heat flow and Moho temperature to evaluate the regional tectonic framework and deep dynamics. The results show that the heat flow in the Chagan Depression ranges from 66.5 to 69.8 mW/ m 2 , with an average value of 68.3 ± 1.2 mW/m 2. The Chagan Depression is characterized by a thin "thermal" lithosphere, high mantle heat flow, and high Moho temperature, corresponding to the lithospheric thermal structure of "cold mantle and hot crust" type. We correlate the formation of the Yingen-Ejinaqi Basin to the Early Cretaceous and Cenozoic subduction of the western Pacific Plate and the Cenozoic multiple extrusions. Our results provide new insights into the thermal structure and dynamics of the lithospheric evolution in central China.

“…(a) There is a well-developed, NNE-trending magmatic belt with both plutonic and volcanic suites, which show progressive younging in age from the west to the east . This eastward-younging, Early Jurassic magmatic system has been widely interpreted as the manifestation of the WNW-directed subduction of the palaeo-Pacific Plate beneath the Asian continent (Wu et al 2007;Yu et al 2012;Zhou et al 2014;Qin et al 2016;Xu et al 2017;Tang et al 2018;Zheng & Dai, 2018). (b) The Early Jurassic plutonic rocks display significant changes in their geochemical characteristics and isotopic fingerprints.…”

Geochemistry and geochronology of OIB-type, Early Jurassic magmatism in the Zhangguangcai range, NE China, as a result of continental back-arc extension

The Zhangguangcai Range in the Xing’an Mongolian Orogenic Belt, NE China, contains Early Jurassic (c. 188 Ma) Dabaizigou (DBZG) porphyritic dolerite. Compared with other island-arc mafic rocks, the DBZG dolerite is characterized by high trace-element contents, relatively weak Nb and Ta enrichments, and no Zr, Hf or Ti depletions, similar to OIB-type rocks. Analysed rocks have (87Sr/86Sr)i ratios of 0.7033–0.7044, relatively uniform positive ɛNd(t) values of 2.3–3.2 and positive ɛHf(t) values of 8.5–17.1. Trace-element and isotopic modelling indicates that the DBZG mafic rocks were generated by partial melting of asthenospheric mantle under garnet- to spinel-facies conditions. The occurrence of OIB-like mafic intrusion suggests significant upwelling of the asthenosphere in response to lithospheric attenuation caused by continental rifting. These processes occurred in an incipient continental back-arc environment in the upper plate of a palaeo-Pacific slab subducting W–NW beneath East Asia.
