“…After the earliest Early Cretaceous compression event, strong extension and magmatic activity occurred in eastern China. A series of metamorphic core complexes, extensional domes and rift basins developed in the central and eastern part of the North China Craton (Zhu R. X. et al, 2020;Zhu et al, 2021). Previous studies on Hefei Basin , Yishu Graben (Zhang et al, 2003;, Linglong extensional dome (Wu et al, 2020) and a series of metamorphic core complexes in North China Craton (Zhu et al, 2021) indicate that the regional principal extensional stress direction during the Early Cretaceous was NWW-SEE to NW-SE.…”

“…During the middle to late Mesozoic, a large-scale lithospheric thinning event occurred in the eastern part of the North China Craton, resulting in the development of a large number of metamorphic core complexes, rift basins and intense magmatic activities Zhu R. X. et al, 2012;Zhu et al, 2015). Controlled by the subduction of the Paleo-Pacific Plate in the western Pacific region during the Mesozoic, a large number of NNE-to NEtrending tectonic traces were superimposed and developed on the continental margin of East Asia (Xu et al, 1987;Zhang et al, 2018;Zhu et al, 2018;Zhang et al, 2020;Zhu et al, 2021).…”

The Qianyingzi Coal Mine is located in the west of the Suxian Mining District of the Huaibei Coalfield, eastern China. The study on structural development patterns and genetic mechanisms in this mine lays an important foundation for safe and efficiently underground mining, and is also the key to understanding the regional tectonic evolution. In this study, based on the analysis of three-dimensional seismic, drilling and underground measured data and regional tectonic correlation, the structures, evolution history and dynamic background of the Qianyingzi Coal Mine are discussed. The Carboniferous-Permian coal measure strata in the mine are generally a gentle syncline with a NNE-trending axis, and cut by a series of faults. The faults developed in this mine are mainly medium- and small-sized with a throw of less than 20 m, and the number of reverse faults is significantly greater than that of normal faults. The strikes of reverse and normal faults are both mainly NE, followed by NNE and nearly N‒S. According to the characteristics of structural geometry, tectonic association, fault property and cross-cutting relation, the structural deformation of coal measure strata in the Qianyingzi Coal Mine can be divided into five stages, and the corresponding tectonic stress fields are NWW‒SEE compressive stress, nearly E‒W compressive stress, NW‒SE compressive stress, nearly E‒W and NW‒SE extensional stresses, respectively. It developed the Fengjia Syncline with a NNE-trending axis in the first stage and nearly N‒S-striking reverse faults in the second stage, which were the results of foreland deformation and subsequent continent-continent collision during the convergence of the North China Craton and South China Plate in the Indosinian period. The NNE-striking reverse sinistral faults and NE-striking reverse faults developed in the third stage is related to the rapid oblique subduction of the Izanagi Plate toward the East Asian continental margin at the beginning of the Early Cretaceous in the western Pacific region. Later, the fourth and fifth stages of the nearly N‒S- and NE-SW-striking normal faults were developed under the backarc extensional background in eastern China during the Early Cretaceous. These new results can be used to guide the rational arrangement for underground mining and also provide a new understanding for regional tectonic evolution of the Huaibei Coalfield.

“…Lode gold deposits are spatially associated with long-lived deep transcrustal faults and formed by large-scale fluid migration during the transition of tectonic settings from a compressional to an extensional stress regime (Bierlein and Crowe, 2000). For instance, Neoarchean lode gold deposits in the Yilgarn craton are distributed in the >100-km-long Boulder-Lefroy shear zone (Weinberg et al, 2005), and those in the Jiaodong district of the NCC occur near the transcrustal Tanlu fault (Zeng et al, 2001;Deng et al, 2020a;Zhu et al, 2021). The second or third order fault systems may control the occurrence of orebodies, whereas the specific locations such as brittle-ductile transition, jogs of second order faults, transforms of fault strikes and offsets of faults are preferential to the precipitation of Au from ore-Figure 1 Global distribution of large orogenic gold deposits with gold reserves over 70 tonnes, modified after Goldfarb et al (2005) and Goldfarb (2021).…”

Lode gold deposits are among the most economically important types of gold deposits in the world. Globally, they formed mainly in three time intervals, 2.8 to 2.5 Ga, 2.1 to 1.8 Ga, and 700 Ma to the present. Sources of ore-forming fluids and other components are of critical importance in a better understanding of the genesis and the geodynamic controls of these deposits. Although ore-forming fluids were mostly derived from devolatization of sedimentary and/or volcanic sequences during greenschist to amphibolite facies metamorphism associated with orogenic deformation, magmatic hydrothermal fluids have been increasingly shown to be important in many gold deposits in various regions. In this review paper, we summarize the major features of lode gold deposits, possible sources of ore-forming fluids, and mechanisms of gold mineralization. While we acknowledge the critical role of metamorphically derived fluids in the genesis of such deposits worldwide, we emphasize that mantle-or basaltic magma-derived fluids may have been much more important than commonly thought. We use the Liaodong peninsula of the North China Craton as an example to demonstrate the significance of mantle-derived fluids. Integrating earlier studies and new data, we show that some of the late Mesozoic lode gold deposits in the North China Craton may have formed from magmatic hydrothermal fluids due to the extension and partial melting of the hydrated, metasomatized subcontinental lithosphere mantle, as best exemplified by the Wulong gold deposit.

“…The NCC consists of Eastern and Western Blocks divided by Trans‐North China Orogen (central orogen) (Zhao et al., 2005) (Figure 1a). The Eastern Block underwent tectonic reactivation (Griffin et al., 1998; Menzies et al., 1993; Xu, 2001) through regional extension between 120 and 130 Ma (Liu et al., 2021; Zhu et al., 2021). This was accompanied by the replacement of ancient lithospheric mantle of the NCC by the present new lithospheric mantle which is thinner and hotter (Wu et al., 2019).…”

The word craton (old kratogen) introduced by Leopold Kober in 1936 indicates interior parts of the continent that are strong and stable. Nowadays cratons are considered ancient stable lithospheric tectonic units that are generally devoid of Phanerozoic magmatic processes, tectonic deformations, and earthquakes (Sengor, 1999). Nevertheless, growing studies have documented that some cratons considered to be stable have experienced episodic rejuvenation events throughout their history (Holdsworth et al., 2001;Lee et al., 2011;Wu et al., 2019). Therefore, rejuvenation of cratons could be considered to be a regular process. Then the rejuvenation of cratons and its associated processes, most probably, play an important role in continental evolution. Imaging and characterizing this process would result in singular new knowledge which contributes to the understanding of the formation and evolution of Earth. The rejuvenation of the cratons (the stable and strong core of the continents) involves: thinning of the lithosphere; increase in crustal and upper mantle temperature gradient; magmatic intrusions; changes in the composition; and, also, tectonic deformation (
