“…In addition, soil bacterial and fungal communities have been shown to exhibit large and significant differences in the stability of certain environmental conditions [30,31]. As mentioned above, curious about the variations of microbial communities in different rock surface soils under the volcanic extreme environment, we studied the variations of microbial communities in different rock surface soils of the Wulanhada Quaternary volcano [32]. This present study intended to further (1) identify the variations of microbial community structure in surface soils of different volcanic rocks, (2) explore major members of the fungal and bacterial communities that inhabit rocky surface soils in volcanic extreme environments, and (3) investigate the influence of various environmental factors on soil microbial communities.…”

“…The Central Asian Orogenic Belt between the North China Plate and the Siberian Plate has an extremely complex evolutionary history, characterized by multi-stage proliferation and suture (Şengör et al, 1993). Therefore, the northern margin of the North China Plate This suggests that the formation background may be related to the subduction of the Paleo-Asian Ocean into the North China Plate in the Early Palaeozoic (Jian et al, 2008;Shi et al, 2004Shi et al, , 2014Zhao, 2010;Zhou, 2012). In this study, the zircon U-Pb ages of Xiaoyingzi and Dongzi granodiorites are 419.4 and 424.5 Ma, respectively, and they were formed in the Late Silurian.…”

“…In the Rb‐(Yb + Ta) and Y‐Nb diagrams (Figure 11a,b), Xiaoyingzi and Dongzi granodiorites and other early Palaeozoic magmatic intrusive bodies in the adjacent area are projected in the volcanic arc granite region, suggesting that the magma may be contributed by subduction plate melting, and the tectonic environment of the granites is classified as active continental margin. This suggests that the formation background may be related to the subduction of the Paleo‐Asian Ocean into the North China Plate in the Early Palaeozoic (Jian et al, 2008; Shi et al, 2004, 2014; Zhao, 2010; Zhou, 2012). In this study, the zircon U–Pb ages of Xiaoyingzi and Dongzi granodiorites are 419.4 and 424.5 Ma, respectively, and they were formed in the Late Silurian.…”

The Shaolang River metallogenic belt in Inner Mongolia is one of the main lead‐zinc polymetallic belt on the northern margin of the North China Plate. The granodiorites, which are closely coexisting with lead‐zinc veins in deposit, are extensively developed. Previous geochronological research results show that the dikes and veins in the metallogenic belt belong to the products of magmatic hydrothermal activity in the middle Yanshanian, so the genesis of the metallogenic belt deposit is generally considered to be a hydrothermal vein type deposit related to sub‐volcanic dikes. We obtained zircon LA‐ICP‐MS U–Pb ages and Hf isotopic compositions of granodiorites, which are widely distributed in the deposit and were considered to be closely connected with the genesis of the deposits. The zircon U–Pb ages are 419.4 ± 1.4 Ma and 424.5 ± 4.1 Ma for the granodiorites, respectively, and they formed in the late Silurian. The geological and geochemical data indicate that the granodiorites are consistent with the geochemical characteristics of typical adakite. All εHf(t) values of the granodiorites are minus, on the zircon Hf isotope age diagram, εHf(t) are below the evolution curve of chondrite. The two‐stage model ages (tDM2) are 2.45 ~ 2.79 Ga and 1.87 ~ 2.29 Ga, respectively, showing rock‐forming materials mainly derived from the Paleoproterozoic and earlier crustal partial melting, and there may have been mantle‐derived magma underplating of the lower crust. Combining with the previous regional research, it is concluded that the granodiorites were formed during the extinction of the island arc under the background of subduction of the Paleo‐Asian Ocean and North China Craton. Because of the 125 ~ 170 Ma metallogenic age, we concluded that the granodiorites in the ore areas have no obvious relationship with the deposit genesis. However, it provided the advantageous space for the formation of the lead‐zinc veins, it can be regarded as an important prospecting indicator in metallogenic belt.

“…The Phanerozoic intrusions in the Zhusileng–Hangwula Belt were generated during the middle–late Devonian (399–373 Ma), late Carboniferous–middle Permian (325–263 Ma) and middle–late Triassic (250–216 Ma), including gabbro, diorite, granodiorite, granite and monzogranite (Fig. 1c; Wang et al 2002; Li, 2006; Han et al 2010; Dang et al 2011; Chen, 2015; Zhang et al 2017; Liu et al 2018a; Shi et al 2018; Chen et al 2019; Li et al 2020; Song et al 2020; Deng et al 2022b, 2023, b; Fei et al 2019; Zhao et al 2020).…”

As the southernmost part of the central segment of the Central Asian Orogenic Belt, the northern Alxa area is characterized by abundant Permian magmatism and records key information on the geological evolution of the Palaeo-Asian Ocean. This study reports new zircon U–Pb and Lu–Hf isotopic and whole-rock geochemical data of the early Permian (285–286 Ma) Huisentala gabbro and Huodonghaer diorites from the Zhusileng–Hangwula Belt in the northern Alxa area. The gabbro is characterized by high Al, Ca, Mg# and light rare-earth elements, and low K, P and high field strength elements (e.g., Ti, Nb and Ta). Furthermore, the gabbro shows heterogeneous zircon ϵHf(t) value (−2.5 to +2.6). The Huodonghaer diorites show high MgO (3.46–6.32 wt%), Mg# (49–58), Sr (408–617 ppm) and Ba (223–419 ppm), and low FeOT/MgO (1.27–1.83) and TiO2 (0.48–0.90 wt%), with geochemical features similar to the high-Mg andesite/diorite. They show radiogenic zircon ϵHf(t) values of +1.2 to +4.9 and high Th/Nb ratios. These features suggest that the Huisentala gabbro and the Huodonghaer diorites were derived from the partial melting of mantle peridotite that was metasomatized by subduction-related fluids and by subducted sediment-derived melts, respectively.
