“…A‐type granite is not only restricted to the Central Orogenic belt, but also occurs in the other parts of the North China craton, such as the Hupiyu monzogranitic gneiss (2180–2150 Ma), the Simenzi granite (2163–2180 Ma), the Muniu monzogranitic (2168 ± 30 Ma) of Liaoji area in the Jiao‐Liao‐Ji orogenic belt (Chen, Yang, et al, 2021; Chen, Zhu, et al, 2021; Liu, Tian, et al, 2020; Zhu et al, 2019), the Chang'e granite (2193–2171 Ma), the Muniushan monzogranitic (ca. 2110 Ma) and Jingqishan granite (2123–2088 Ma) of the Jiaobei area in the Jiao‐Liao‐Ji orogenic belt (Cheng et al, 2017; Lan et al, 2015; Zhang, Liu, Xu, et al, 2022), and the Shimenshan granite (2096 ± 9 Ma) and Fengyang granite gneiss (2096 ± 8 Ma) of the Wuhe Group of the Anhui area of the Jiao‐Liao‐Ji orogenic belt (Wang, Liu, Zhang, Zhao, Wang, & Song, 2017). The extensive distribution of A‐type granites in the North China craton suggests that the craton experienced an extensional event at ca.…”

Tectono‐thermal records older than ca. 1.8 Ga in the North China craton have been poorly resolved given that they have been strongly overprinted by younger events, despite being key to understanding the tectonic evolution of the craton. We report results of monazite Th–U–Pb isochron geochronology via electron probe microanalysis on the Zanhuang massif in the North China craton, to determine its detailed Precambrian tectono‐thermal history. Results suggest that the ca. 2.1 Ga tectono‐thermal event can be divided into distinct ca. 2.17 Ga and ca. 2.10 Ga stages, reflecting metamorphism related to retroarc regional extension of the North China craton. Similarly, the previously established ca. 1.8 Ga metamorphic event can be divided into distinct ca. 1.88 Ga and ca. 1.79 Ma stages. Through a detailed summary and comparison, we interpret that the ca. 1.88 Ga monazite age reflects the timing of peak metamorphism, which was followed by ca. 1.79 Ga retrogression.

“…The JLJB has experienced multiple stages of metamorphic-deformational and magmatictectonic events [9,[14][15][16][17]19,20,34,36,37,49,54]. These events have made reconstructing the tectonic evolution of the JLJB extremely challenging.…”

“…While it is widely accepted that the JLJB was formed by the collision between the Longgang and Nangrim blocks, ongoing debates exist about the belt's tectonic nature (rift versus collision models; e.g., [6,11,12]). A comprehensive understanding of the Paleoproterozoic sedimentation, metamorphism and magmatism is key to resolving this controversy [9,[13][14][15][16][17][18][19][20]. The widely exposed meta-igneous and metasedimentary rocks (schist, gneiss, marble, felsic gneiss, granulite and amphibolite) of the Ji'an Group, as well as the related voluminous granites (gneissic granite and porphyritic granite), provide evidence of multiple metamorphic-deformational and magmatic-tectonic events, which could serve as strong constraints on the tectonic evolution of the JLJB.…”

Tectonic Evolution of the JLJB, North China Craton, Revisited: Constraints from Metamorphism, Geochemistry and Geochronology of the Ji’an Group and Related Granites

et al. 2023

The Jiao-Liao-Ji Belt (JLJB) is the most representative Paleoproterozoic orogenic belt in the North China Craton (NCC). The sedimentation, metamorphism and magmatism of the Ji’an Group and associated granites provide significant insights into the tectonic evolution of the JLJB. In this study, we have synthesized published geochemistry and geochronology data on metasedimentary, metavolcanic and igneous rocks. According to the available data, the protoliths of the metasedimentary rocks are sets of shale, wacke, arkose, quartz sandstone and carbonate, while the protoliths of the metavolcanic rocks are calc-alkaline basalt, basaltic andesite, andesite, dacite and rhyolite. The rock assemblages indicate a transformation of the tectonic environment from a passive margin to an active continental margin following the onset of plate convergence and subduction. The A2-type gneissic granite (Qianzhuogou pluton) is formed in a subsequent back-arc basin extension setting at 2.20–2.14 Ga. The Ji’an Group was finally deposited in an active continental margin during the closure of a back-arc basin at 2.14–2.0 Ga. Then, the sediments were involved in a continent–arc–continent collision between the Longgang and Nangrim blocks at ~1.95 Ga. This process was accompanied by HP granulite-facies metamorphism at ~1.90 Ga. The subsequent exhumation and regional extension resulted in decompression melting during 1.90–1.86 Ga, producing metamorphism with an isothermal decompression clockwise P–T path. The resulting metapelites are characterized by perthite + sillimanite, and mafic granulites are characterized by orthopyroxene + clinopyroxene. The S-type porphyritic granite (Shuangcha pluton) is formed during the crustal anatexis. Meanwhile, extensive anatexis produced significant heating and triggered prograde to peak metamorphism with an anticlockwise P–T path. Cordierite-bearing symplectites around the garnet in the metapelites indicate a superposed isobaric cooling metamorphism. The ages of monazites and anatectic zircons suggest that the post-exhumation cooling occurred at 1.86–1.80 Ga. The Paleoproterozoic magmatism, sedimentation and metamorphism suggest a process of subduction back-arc basin extension and closure, collision and exhumation for the tectonic evolution of the JLJB.
