Geochronology and geochemistry of middle Permian–Middle Triassic intrusive rocks from central–eastern Jilin Province, NE China: Constraints on the tectonic evolution of the eastern segment of the Paleo-Asian Ocean

“…The studied area experienced postcollisional extensional environment during the early stage of the late Paleozoic (Early-Middle Devonian-early Carboniferous) (Wang et al, 2015a(Wang et al, , 2015b(Wang et al, , 2015c. However, in early Permian, the northern margin of the NCC and northern accretionary belt experienced the southward subduction of the Paleo-Asian oceanic plate again .…”

“…At present, the dominant views are that final closure occurred in the Middle Devonian (Xu and Chen, 1997;Xu et al, 2015), the Late Devonian-early Carboniferous (Hong et al, 1995;Shao, 1991;Tang, 1989Tang, , 1990Zhao et al, 1996), the early-middle Permian (Feng et al, 2010;Liu et al, 2010a;Ren et al, 1980;Wang et al, 1991), the Early Triassic , the early Late Triassic (Xin et al, 2011), the middle Mesozoic (Nozaka and Liu, 2002), or the late Permian-Early Triassic Li, 1998Li, , 2006Peng et al, 2012;Sengör et al, 1993;Sun et al, 2004;Wang et al, 2015b;Wu et al, 2007;Xiao et al, 2003;Zhang et al, 2004;Zhang et al, 2009;Zhao et al, 2010). The closure style of the Paleo-Asian Ocean is also an unresolved issue; for instance, was closure a one-time or a scissor-style event Sun et al, 2004;Wang et al, 2015b;Zhang, 2014)?…”

“…An understanding of the Paleozoic relationships between these microcontinental massifs and the North China Craton (NCC) is important for furthering our knowledge of the tectonic evolution and timing of final closure of the Paleo-Asian Ocean. Although recent studies have greatly enhanced our understanding of the Paleozoic evolution of the Paleo-Asian Ocean along the western segment of the northern margin of the NCC (Li et al, 2009;Li et al, 2014c;Ma et al, 2011;Xu et al, 2014;Yang et al, 2006;Zhang et al, 2014), less research has been conducted on the Paleozoic (especially late Paleozoic) tectonic evolution of the eastern segment of the northern margin of the NCC, and the sequence of tectonic events in the area remains controversial Pei et al, 2014;Wang et al, 2015b;Wang et al, 2015c;Xu et al, 2015). Some scholars, based on analyses of sedimentary sequences and paleontological evidence, have suggested that a passive continental margin existed along what is now the eastern segment of the northern margin of the NCC during the late Paleozoic (e.g., Hsu et al, 1991;Jia et al, 2004;Li, 1998;Xu et al, 2014;Zhang et al, 2008).…”

“…NE China is located in the eastern section of the Central Asian Orogenic Belt (CAOB), which is usually called as the Xing'an-Mongolia Orogenic Belt (XMOB) in the Chinese literature Sun et al, 2004;Wang et al, 2015b). The region consists of a collage of several microcontinental massifs, which, from southeast to northwest, are the Khanka, Jiamusi, Songnen-Zhangguangcai Range, Xing'an, and Erguna massifs, all of which are separated from one another by major faults (Jahn et al, 2000;Li, 2006;Li et al, 1999;Li et al, 2014c;Sengör et al, 1993;Xie, 2000;Ye et al, 1994;Fig.…”

U–Pb ages and Hf isotopic composition of zircons and whole rock geochemistry of volcanic rocks from the Fangniugou area: Implications for early–middle Paleozoic tectonic evolution in Jilin Province, NE China

“…Third, the early Devonian Sandaogou alkaline complex of south Inner Mongolia and the late Devonian I-A-type rhyolites from Jifanggou Group of central Jilin Province formed in a post-collisional extensional environment associated with collisional events along the northern margin of the NCC during the latest early Paleozoic (Zhang et al, 2010a;Wang et al, 2015b). Fourth, the middle-late Devonian Wangjiajie Formation and Xiaosuihe Formation of central Jilin Province are composed mainly of marine clastic units and carbonate, which formed under a stable environment that related to a post-collisional extensional environment (JBGMR, 1988;Wang et al, 2015a). Fifth, the varied detrital zircon Hf isotopic compositions from the Devonian clastic rocks (e.g., Wangjiajie sandstone and Zhangjiatun rhyolitic breccias) of central Jilin Province imply two sources with ancient and juvenile features respectively (Fig.…”
