“…The major lines of evidence for the intracontinental rift model include the occurrences of bimodal volcanic rocks, rift-related boron deposits, A-type granites, and early extensional deformation, as well as metamorphism with an anticlockwise P-T path [8,10,11]. More recently, an increasing number of studies have suggested that the JLJB was formed by arc/continent-continent collision [19][20][21][22][23][24][25][26][27][28][29][30][31] or underwent an integrated process of intracontinental rifting, emergence of a small ocean, subduction, and collision [2,[5][6][7]32]. Although progress has been made in understanding the metamorphism, magmatism, and structural deformation of the JLJB, the tectonic evolution of the belt is still not fully resolved.…”

The Jiao-Liao-Ji belt (JLJB), in the Eastern Block of the North China Craton, is a major Paleoproterozoic orogen and underwent a complicated tectonic evolution during 2.2–1.8 Ga. The Liaohe Group, an important stratigraphic unit in the JLJB, is key to understanding the complex evolution of this belt. In this paper, we present new detrital zircon U–Pb ages and Hf isotope data for meta-sedimentary rocks from the Gaixian Formation in different areas of the JLJB, in addition to compiled data for other formations of the Liaohe Group, to establish the depositional age and source of detrital materials of the group. U–Pb age results show that the age ranges of zircons from the different samples are broadly similar. The youngest zircon group is ca. 2.06 Ga, and the youngest single-grain age is ca. 2.0 Ga, constraining the depositional age of the Gaixian Formation to between 2.0 Ga and the metamorphic age of ca. 1.9 Ga. The zircon age data indicate that the provenance was primarily Archaean basement of the Nangrim Block and Paleoproterozoic volcanic rocks of the Li’eryu Formation. On the basis of the new geochronological data and results from previous studies, it is inferred that the JLJB underwent a successive process of rifting–subduction–collision, with the different formations of the Liaohe Group being deposited in different stages from rift to passive continental margin and then to active continental margin. Zircon Hf isotope data from the JLJB and adjoining Longgang and Nangrim blocks indicate that a major crustal growth event occurred at 2.9–2.5 Ga, followed by crustal growth and intense recycling of ancient crust at ca. 2.2 Ga.

“…2.1 Ga, A-type granite in the Central Orogenic belt is well documented, such as the Huangjinshan granite (2137 ± 9 Ma) of the Wutai massif (Du et al, 2013), the Dawaliang granite (2170 ± 17 Ma) of the Wutai massif (Du et al, 2018), the Nanying, Gangnan and Baiyangling granite gneisses (2080-2070 Ma) of the Fuping massif (Wang et al, 2020), the Lingyunkou granite (2080-2050 Ma) of the Hengshan massif (Zhao et al, 2011), the Chijianling-guandimiao granite gneiss (2180-2130 Ma) of the Luliang massif (Liu et al, 2021), the Tongkuangyu meta-acidic volcanic (2143 ± 11 Ma) of the Zhongtiao massif (Yang et al, 2015) and potassic granite (2194 ± 29 Ma) of the Lushan massif (Zhou et al, 2014). 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).…”

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 early Paleoproterozoic (ca. 2.2–2.1 Ga) tectonic evolution of the Jiao–Liao–Ji belt (JLJB) is a continuous hot topic and remains highly controversial. Two main tectonic regimes have been proposed for the JLJB, namely arc-related setting and intra-continental rift. Abundant ca. 2.2–2.1 Ga volcanic rocks were formed in the JLJB, especially in the Liaodong Peninsula. These ca. 2.2–2.1 Ga volcanic rocks therefore could host critical information for the evolution of the JLJB. In this study, we report a suit of ca. 2.2–2.1 Ga felsic metavolcanic rocks in the Liaodong Peninsula of the JLJB to provide new insights into the above issue. Zircon U-Pb dating reveals that the felsic metavolcanic rocks were erupted at 2185–2167 Ma. They have variable εHf(t) values (−0.70 to +9.69), high SiO2 (66.30–75.30 wt.%) and relatively low TiO2 (0.03–0.78 wt.%), tFe2O3 (0.55–5.03 wt.%), MgO (0.17–8.76 wt.%), Cr (9.16–67.30 ppm), Co (2.01–7.00 ppm) and Ni (3.90–25.70 ppm) contents with enrichments in light rare earth element (REE) and large ion lithophile element (LILE), and depletions in heavy REE and high field strength element (HFSE). Geochemical and isotopic results indicate that the felsic metavolcanic rocks were sourced from partial melting of ancient Archean TTG rocks and juvenile lower crustal materials. Combined with coeval A-type granites, bimodal volcanic rocks and the absence of typical arc magmatism, the most likely tectonic regime at ca. 2.2–2.1 Ga for the JLJB is an intra-continental rift.
