| 摘 要： | The southern Great Xing’an Range is the most critical Sn-polymetallic metallogenic belt in northeast China. However, the tectonic setting of the Early Cretaceous magmatic-metallogenic ”flare-up“ event remains uncertain. This paper presents an integrated study on the occurrence, petrology, zircon U-Pb ages, whole-rock geochemistry, and in situ zircon Hf isotopes for Wenduerchagan granites of Xi Ujimqin Banner, central-eastern Inner Mongolia. These granites consist primarily of granite porphyry(wi...
