LA-ICP-MS zircon dating, geochemistry, petrogenesis and tectonic implications of the Dapingliang Neoproterozoic granites at Kuluketage block, NW China

► Neoproterozoic magmatism and mineralisation with emplacement age of the Dapingliang granites constrained between ca. 816 and 826 Ma. ► The Dapingliang granites maybe formed by partial melting of K-rich basalt of the lower crust during a period of transition from crustal compression to extension. ► A post-collisional granite belt derived from lower crust in the Kuluketage block was determined.
