“…The analytical Y o u f a n g z h u a n g F a u l t A 5 km procedure followed that described by Wang et al (2013). The samples were powdered using a tungsten carbide ball mill and were dried in an oven at 105°C for 2 h. Major element contents of samples 10TB11, 10TB13, 10TB18, and 10TB21 were analyzed by wet chemical methods according to Chinese national standard (GB/T4506-2010) at State Key Laboratory of Geological Processes and Mineral Resources (GPMR), China University of Geosciences (Wuhan).…”

“…Similar to the famous Central Asia Orogenic Belt where the Phanerozoic crustal growth mainly occurred in island arc and/or backarc settings (Kröner et al, 2007(Kröner et al, , 2013Safonova et al, 2011), the Ordovician-Silurian igneous rocks from the North Qinling-Tongbai orogen highlight the back-arc environment for the growth of continental crust in an extensional accretionary orogen and thus provide a key Shervais (1982)); (b) Ba/Nb vs. Ba/Yb diagram (Island arc basalt (IAB) trend lines are plotted using data from the South Sandwich Island IAB samples from Pearce et al (1995); back-arc basin basalt (BABB) trend lines are plotted using data from the Segment E2, East Scotia Ridge samples from Leat et al (2000)); (c) Ti/ 50-50 × Sm-V diagram (after Vermeesch (2006)). The data for the Erlangping basaltic rocks are from Wang et al (2013) and the references therein.…”

“…Wang et al, 2013). The eclogites from the Qingjiagou, Guanpo, Kanfenggou and Shijiagou areas in the North Qinling terrane have a consistent U-Pb age of 796 ± 13 Ma, 814 ± 45 Ma, 791 ± 6 Ma, 798 ± 23 and 799 ± 94 Ma on magmatic zircon cores within analytical errors (Chen and Liu, 2011;Wang et al, 2011;H. Wang et al, 2013), indicating a similar protolith age of ca.…”

“…However, the hypothesis of the first continent-continent collision needs to be supported by the coinstantaneous metamorphism of the Kuanping Group, and the Neoproterozoic E-MORB and younger detrital zircon ages obtained for metasedimentary rocks from the Kuanping Group also need to be reasonably interpreted. By contrast, in order to interpret the origin of UHP rocks in the Qinling Group, Zheng (2013a, 2013b) and Wang et al (2013b) advocated that the Qinling microcontinent was split from the SCB at ~800 Ma, and accreted to the southern margin of the NCB in the period of 490-480 Ma. During this process, the earlier oceanic subduction produced an accretionary wedge represented by the Kuanping Group in the southern margin of the NCB, and the following deep continental subduction beneath the NCB resulted in the formation of UHP rocks (Figure 3(b)).…”
