“…However, in the ages of collision in the western part of Qinling show a range of 228 to 215 Ma (Dong et al, ) with subduction‐related granitoids and syn‐collisional granitoids (Dong & Santosh, ; Wang, Wang, & Zhang, ) formed later than those in the eastern part of Qinling (240 to 220 Ma, Li, Chen, Cong, et al, ; Ames et al, ; Eide, Mc Williams, & Liou, ). Therefore, the mineral deposits formed in this period might belong to both subduction and collision environments (Dong & Santosh, ; Liu et al, ; Mao et al, ; Wang et al, ).…”

“…The Xiahe, Amishan, Dewulu, and Meiwu intrusions and intermediate and acidic dykes in this region were formed in the middle Triassic. Zircon U–Pb ages between 245 and 230 Ma (Jin et al, ; Xu, Chen et al, ; Xu, Liu et al, ; Luo et al, ; Sui & Li, ; Zhang, et al, ) suggest that these rocks formed in the subduction–collision setting (Dong & Santosh, ; Liu et al, ). Granites that developed in the Xiahe and Zhiliguan area are characterized by I‐type affinity with a high‐Mg # value, suggesting the involvement of mantle‐derived components in the partial melting of deep crust within a subduction setting.…”

“…The West Qinling Orogen is one of the most important gold producing regions in China and has drawn international attention (e.g., Chen & Santosh, ; Goldfarb, Taylor, Collins, Goryachev, & Orlandini, ; Mao et al, ). Since the 1980s, more than 50 gold deposits have been discovered in the east‐trending thrust and sutural zones in West Qinling Orogen (Figure ), including some large deposits with over 50 t Au reserves such as Dashui, Manaoke, Dongbeizhai, Jianchaling, and Zhaishang Au deposits (Chen et al, ; Liu et al, ; Mao et al, ; Zhang et al, ). Interestingly, those classified into orogenic gold deposits are located in the northern SQB and along Shangdan Suture, whereas most of the Carlin‐type and Carlin‐like Au deposits occur in the southern SQB as well as along the Mianlue Suture (Chen & Santosh, ; Mao et al, ).…”

“…Detailed investigations of the individual intrusions have been carried out in geology, geochronology, and geochemistry since 1990s (e.g., Deng, Liu, Zhang, Hu, & Li, ; Jiang et al, ; Li et al, ; Li et al, ; Liu et al, ; Luo, Zhang, & Lü, ; Qin, Lai, & Li, ; Qin, Lai, Wang, & Li, ; Qin et al, ; Qin et al, ; Qin, Lai, Wang, & Li, ; Qin, Lai, Diwu, Ju, & Li, ; Sun, Li, Sun, Zhang, & Li, ; Wang et al, ; Wang, Wang et al, ; Wang, Wang, & Zhang, ; Yang et al, ; Yang, Liu et al, ; Zhang, Jin et al, ; Zhang, Xiao, Zhang, Yuan, & Jin, ; Zhu et al, ). In addition to the Early Mesozoic granitoids, the other attractive geological features in the Qinling Orogen is the extensive distribution of gold deposits (Figure ; Jin, Li, Hofstra, & Sui, ; Liu, Lui et al, ; Liu, Dai et al, ; Liu, Lui et al, ; Liu, Liao et al, ; Mao et al, ; Zeng et al, ; Yang, Deng et al, ; Yang, Liu, et al, ), which were classified as orogenic (Chen et al, ; Chen & Santosh, ; Mao et al, ), Carlin‐type (Chen, Zhang, Zhang, Pirajno, & Li, ; Yang, Zhu et al, ) and Carlin‐like (Liu, Dai et al, ; Liu, Tan, Wang, & Wei, ; Zhang, Du, Wang, & Qi, ) in view of mineralization style, alteration assemblages, and geochemical signatures. Although the Early Mesozoic granitic intrusions are widespread over the West Qinling Orogen, their petrogenesis and tectonic implications have not yet been addressed in detail, more importantly their role in gold mineralization is controversial and poorly understood.…”
