Abstract: To reveal the petrogenesis of Baitai granite in Jiulong area and its relationship with rare metal mineralization, petrographic, whole-rock geochemistry, LA-ICP-MS zircon U-Pb geochronology, zircon trace element geochemistry and Hf isotope geochemistry were studied in this paper. Samples from the Baitai biotite monzonitic granite are characterized by high SiO2 contents（69.01%～70.55%）, high K2O（3.86%～4.99%）, high alkali（K2O+Na2O=7.41%～8.18%）, low CaO（1.4... More
