...Liuqing Jiang; Wei Li; Yunpeng Dong; Le Zhang; Li Liang; Falak Sheir Abstract We studied the zircon U–Pb ages, whole-rock geochemistry and Sr–Nd isotopic compositions of a Paleozoic gabbro–diabase–granite association in the Shangdan suture zone to constrain the petrogenesis of these intrusive rocks...

... and geochemical features may provide potential clues with which to reconstruct the corresponding thermotectonic history and are therefore helpful for our understanding of orogenic evolution. The North Qinling terrane is located between the Luonan-Luanchuan fault and the Shangdan suture zone ( Figs. 1A and 1B...

...Figure 13. Cross-section shows the structures of the Qinling Orogenic Belt. SD suture—Early Paleozoic Shangdan suture zone; ML suture—Triassic Mianlue suture zone; WT fault—Late Jurassic–Early Cretaceous Wuxi–Tiexi thrust fault; B fault—Late Triassic and Late Jurassic–Early Cretaceous Bashan arc...

...Chao Cheng; Shengsi Sun; Yunpeng Dong; Bin Zhang; Zhao Guo Abstract The Taibai granitic plutons lie between the Taibai ductile shear zone to the north and the Shangdan suture to the south. The deformation mechanism of the ductile shearing is crucial to understanding the exhumation processes...

... ; Ratschbacher et al., 2003 , 2006 ; Bader et al., 2013 ; Dong and Santosh, 2016 ; Liu et al., 2016 ; Tang et al., 2016 ). Two Paleozoic ophiolitic mélange zones, from north to south, the Erlangping and Shangdan sutures, have been revealed in the Qinling orogenic belt, constraining Paleozoic subduction...

... of Asia. This belt separates the North China and South China blocks. Extensive, thick Devonian clastic rocks, sandwiched between the Shangdan and Mianlue suture zones, are mainly infills of the Xicheng Basin and provide the principal sedimentary record of tectonism in the Qinling orogen. Devonian infills...

... comprises two sutures and three blocks ( Meng & Zhang, 1999 , 2000 ; Fig. 1 ). The Shangdan suture separates the North China Block (including the North Qinling belt) from the Qinling microplate (the South Qinling belt), and the Mianlue suture separates the Qinling microplate from the South China Block...
