Petrogenesis of late Cenozoic basalts from Dalinor, Inner Mongolia: Implications for lateral mantle heterogeneity in eastern China

We present major element, trace element and Sr-Nd-Pb-Hf isotopic compositions of the late Cenozoic basaltic rocks from Dalinor, Inner Mongolia, on the west of the Greater Hinggan Mountain Range in Northeast Asia, and discuss the origin of mantle source heterogeneity beneath Northeast Asia. The early-stage volcanoes (EV) from Dalinor produced predominantly quartz tholeiitic and olivine tholeiitic basalts whereas the late-stage volcanoes (LV)...
