Geochemistry,zircon U-Pb geochronology and in-situ Hf isotope of the Maiga batholith in Coqen,Tibet:Constraints on the petrogenesis of the Early Cretaceous granitoids in the central Lhasa Terrane

The magma source and petrogenesis of the Early Cretaceous granitoids,which widely exposed in the central Lhasa Terrane,Tibet,remain unconstrained so far.A better understanding of such issues will help us to reveal the magmatic processes and mineralization setting of the Lhasa Terrane during the Cretaceous.This paper reports zircon U-Pb age,whole-rock geochemistry,Sr-Nd isotopic data and zircon Hf-isotope data from the Maiga batholith,which is...
