Tectonic switch of the north Yangtze Craton at ca. 2.0 Ga: Implications for its position in Columbia supercontinent

Tectonic affinity and geological significance of the Feidong Complex in the northeastern margin of the Yangtze Craton: Evidence from zircon U–Pb and Lu–Hf isotopes of the basement rocks

“…Previous studies have extensively investigated the distinct histories of Precambrian crustal evolution in the North China and Yangtze cratons (Deng et al, 2019; Jia et al, 2019; Li et al, 2024; Tian et al, 2022; Wan et al, 2018, 2023; Zhai et al, 2015; Zhang et al, 2013, 2022; Zhao et al, 2021; Zhao & Cawood, 2012; Zheng et al, 2013; Zhou & Zhai, 2022). The North China Craton, with a geological history dating back to ca.…”

“…Recent research has also reported magmatism at ca. 2.5 Ga in the northern margin of the Yangtze Craton, predominantly exposed in the Douling Complex (Hu et al, 2013; Wu et al, 2014), Yudongzi Complex (Chen et al, 2019; Hui et al, 2019; Zhou et al, 2018), Jiamiao Complex (Tian et al, 2022), Jinpan Complex (Zhang et al, 2022), Xishui Complex (Zhao et al, 2021) and Susong Complex (Wang et al, 2020, 2021). The magmatic rocks of this period are characterised by negative ε Hf (t) values, with corresponding two‐stage Hf model ages (T DM2 ) ranging from 2.7 to 3.7 Ga (Figure 8f).…”

“…Similarly, the widespread Paleoproterozoic rocks (ca. 2.0 Ga) were found in the northern margin of the Yangtze Craton, which also displayed negative ε Hf (t) values and two‐stage Hf model ages of 2.5–3.4 Ga (Guo et al, 2014, 2015; Han et al, 2017, 2018, 2019; Li et al, 2014; Wang et al, 2015, 2019, 2021; Wu et al, 2008, 2012; Yin et al, 2013; Xu et al, 2020; Zhang, Zheng, et al, 2020; Zhang et al, 2022; Figure 8c,f). However, there has been a scarcity of ca.…”

“…2.5 Ga) (Hu et al, 2013; Wu et al, 2014), Tongbai–Hong'an (ca. 2.46 and 2.0 Ga) (Xu et al, 2020; Zhang et al, 2022; Zhang, Gao, et al, 2020), Huangtuling (ca. 2.9–2.7 and 2.0 Ga) (Sun et al, 2008; Wu et al, 2008), Muzidian (ca.…”

“…2.70–2.65 and 2.50–2.47 Ga (Zhang, Zheng, et al, 2020), subduction–collision orogenic event at ca. 2.1–1.93 Ga during Mid–Late Paleoproterozoic (Han et al, 2017, 2018; Wang et al, 2021; Wu et al, 2012; Xu et al, 2020; Zhang et al, 2022; Zhang, Gao, et al, 2020) and subsequent extensional events at ca 1.85–1.7 Ga (Deng et al, 2017; Han et al, 2019; Hui et al, 2017; Peng et al, 2012; Xiong et al, 2009; Zhang, Gao, et al, 2020; Zhou et al, 2017). Furthermore, Neoproterozoic magmatism in the northern Yangtze Craton is known to be associated with the breakup of the Rodinia supercontinent (Cawood et al, 2018, 2020; Zhang & Zheng, 2013; Zhao et al, 2018; Zhao & Cawood, 2012).…”
