摘　　要：This paper reports geochemistry （major and trace elements）, zircon U-Pb and Lu-Hf isotope studies of leucogranite, granodiorite and clinopyroxene-bearing diorite from the Zengga intrusive body, eastern Gangdese batholith, Tibet. Massive granodiorite is mainly composed of fine- and medium-grained plagioclase （65 modal %）,This paper reports geochemistry （major and trace elements）, zircon U-Pb and Lu-Hf isotope studies of leucogranite, granodiorite and clinopyroxene-bearing diorite from the Zengga intrusive body, eastern Gangdese batholith, Tibet.
