Two-stage magmatic events of the early Paleozoic in the eastern Hexi Corridor Belt, NW China: petrogenesis and tectonic implications

The petrogenesis and geodynamic implications of the early Paleozoic magmatic events in the eastern Hexi Corridor Belt, NW China, remain poorly constrained. In this study, we present high-quality zircon U–Pb ages as well as geochemical and zircon Lu–Hf isotopic data for three early Paleozoic intrusive rocks from the Mafuxiazi area in the eastern Hexi Corridor Belt. The LA-ICP-MS U–Pb dating results suggest that there are two stages of magmatic...
