Pamir syntax is one of the strongly tectonic compression areas in Tibetan Plateau and a typical area of crustal shortening and thickening during continental collision(Burtman, 2000; Ducea et al., 2003; Robinson et al.,2004, 2007). The Taxkorgan alkalic complex is mainly distributed in the mid-east region of Pamir syntax and is the largest Cenozoic intrusive rock in the region.Therefore, the origin and time of Taxkorgan alkalic complex is particularly important for the lithosphere shortening and thickening, crust-mantle interaction as well as the uplift process of the plateau(Luo et al.,2003; Ke et al., 2006, 2008; Xu et al., 2017).Here, we present a new study of SHRIMP U-Pb and Ar/Ar geochronology, whole-rock major and trace elements of the Zankangou diopside syenites in Taxkorgan area, in order to constrain the petrogenesis and source region of these rocks. *
