“…However, direct evidence of widespread late Archaeanearly Palaeoproterozoic basement for the SCB has not been reported. The Douling, Kongling, Phan si Pan, Yudongzi and Zhongxiang complexes, which represent the oldest rocks of the Yangtze Block, are only distributed along the northern and southern Yangtze margins (Qiu & Gao, 2000;Lan et al 2001;Zhang et al 2001Zhang et al , 2010Nam et al 2003;Zheng et al 2006;Jiao et al 2009;Gao et al 2011;Wang et al 2011Wang et al , 2018Hu et al 2013;Wu et al 2014;Nie et al 2016;Hui et al 2017).

“…Archaean-Palaeoproterozoic crystalline basement of the Yangtze Block is sporadically exposed and is represented by the Douling Complex, which has yielded ages of~2.5 Ga (Hu et al 2013;Wu et al 2014;Nie et al 2016), the Kongling Complex, yielding ages in the ranges of 3.2-2.9 Ga, 2.7-2.4 Ga and 2.1-1.8 Ga (Gao et al 1999;Qiu & Gao, 2000;Zheng et al 2006), the Phan si Pan Complex, yielding ages in the range of 2.9-2.8 Ga (Lan et al 2001;Nam et al 2003), the Yudongzi Complex, yielding ages in the range of 2.8-2.45 Ga (Zhang et al 2001(Zhang et al , 2010Wang et al 2011;Hui et al 2017), and the Zhongxiang Complex, yielding ages in the range of 2.9-2.6 Ga (Wang et al 2013a(Wang et al ,b, 2018Zhou, G.

Provenance investigation for the Cambrian–Ordovician strata from the northern margin of the western Yangtze Block: implications for locating the South China Block in Gondwana

We report new U–Pb isotopic data for detrital zircons from Cambrian–Ordovician strata on the northern margin of the western Yangtze Block, which together with published U–Pb isotopic data for coeval strata in the South China Block, provide critical constraints on the provenance of these sediments and further shed light on the early Palaeozoic position of the South China Block in the context of Gondwana. Detrital zircons in this study yield four major age peaks in the early Palaeoproterozoic, early Neoproterozoic, middle Neoproterozoic and late Neoproterozoic – early Palaeozoic. The dominant age population of 900–700 Ma matches well with magmatic ages from the nearby Panxi–Hannan Belt, which indicates that Cambrian–Ordovician sedimentary rocks in the western Yangtze Block were mainly of local derivation. However, compilations of detrital zircon ages for the Cambrian–Ordovician strata from the Cathaysia Block and the eastern Yangtze Block show that both blocks are dominated by late Mesoproterozoic- and early Neoproterozoic-aged detrital zircons, which suggests a remarkable exotic input with typical Gondwana signatures. According to the integrated detrital zircon age spectra of the Cambrian–Ordovician sedimentary rocks from the entire South China Block and palaeocurrent data, the South China Block should have been linked with North India and Western Australia within East Gondwana. Specifically, the Cathaysia Block was located adjacent to Western Australia, while the Yangtze Block was connected with North India.

“…In the Yangtze Block, the Archean rocks crop out sporadically in the Kongling TTG complex, Jinshan K-feldspar granite and Douling complex, which have been dated at 3.45-2.6 Ga (Qiu et al, 2000;Jiao et al, 2009;Gao et al, 2011;Chen et al, 2013a;Guo et al, 2014), 2655 ± 9 Ma (Wang et al, 2013a), and ca. 2.5 Ga Wu et al, 2014), respectively. The zircon grains from the Douling complex are characterized by continental crust-like Hf and O isotopes, with ε Hf (T) = −4.5 to −1.1 and ␦ 18 O = 4.8-6.9‰ .…”

“…According to the tectonic position, the Tongbai HP metamorphic terrane seems to be connected with the Douling complex. However, the new study suggests that the Douling complex is a Neoarchean (~2.5 Ga) segment metamorphosed at ~820-780 Ma and intruded by numerous diorites, granodiorites and granites at ~730-700 Ma Bader et al, 2013b;Liu and Zhang, 2013;Wu et al, 2014). Although Bader et al (2013b) identified a few Triassic zircon grains from paragneisses and intrusives, we obtained two biotite 40 Ar/ 39 Ar ages from paragneisses at 814±4 and 790±4 Ma, respectively (our unpublished data), implying a very weak influence of Early Mesozoic tectono-metamorphic event on the Douling complex.…”

The Tongbai-Hong'an orogen is located in a key tectonic position linking the Qinling orogen to the west and the Dabie-Sulu orogen to the east. Because the orogen preserves a Paleozoic accretionary orogenic system in the north and a latest PaleozoicMesozoic collisional orogenic system in the south, it may serve as an ideal place to study the tectonic evolution between the North and South China Blocks. The available literature data in the past 20 years indicate that the tectonic processes of the Tongbai-Hong'an orogen involved four stages during the Phanerozoic: (1) Early Paleozoic (490-420 Ma) oceanic subduction, arc magmatism and arc-continent collision created a new Andean-type active continental margin on the North China Block; (2) Late Paleozoic (340-310 Ma) oceanic subduction and accretion generated separated paired metamorphic belts: a medium P/T Wuguan-Guishan complex belt in the south of the Shandan-Songpa fault and a high P/T Xiongdian eclogite belt in the northern edge of the Mesozoic HP metamorphic terrane; (3) Latest Paleozoic-Early Mesozoic (255-200 Ma) continental subduction and collision formed the Tongbai HP terrane in the west and the Hong'an HP/UHP terrane in the east as a consequence of deep subduction towards the east and syn-subduction detachment/exhumation of the down-going slab; (4) Late Mesozoic (140-120 Ma) extension, voluminous magma intrusion and tectonic extrusion led to the final exhumation of the Tongbai-Hong'an-Dabie HP/UHP terrane and the wedge-shaped architecture of the terrane narrowing towards the west. However, many open questions still remain about the details of each evolutionary stage and earlier history of the orogen. Besides an extensive study directly on the Tongbai-Hong'an orogen in the future, integrated investigation on the "soft-collisional" Qinling orogen in the west and the "hard-collisional" Dabie-Sulu orogen in the east is required to establish a general tectonic model for the whole Qinling-TongbaiHong'an-Dabie-Sulu orogenic belt. oceanic subduction, accretion, continental subduction, collision, Tongbai-Hong'an orogen Citation: Liu X C, Li S Z, Jahn B M. 2015. Tectonic evolution of the Tongbai-Hong'an orogen in central China: From oceanic subduction/accretion to continent-continent collision. Science China: Earth Sciences,Orogens lying at convergent plate margins can be divided into accretionary orogens and collisional orogens (Cawood et al., 2009). Accretionary orogens form through the continuing subduction of oceanic lithosphere and can be further grouped into retreating and advancing types. The former is represented by the trench-arc-basin system of the West Pacific, and the latter by the Andean orogenic belt of the East Pacific. Collisional orogens form through continent-continent collision at the termination of oceanic subduction. The most typical example is the Alpine-Himalayan orogenic belt.
