Two granitic plutons in Central Western Kunlun Belt: Their ages and possible sources

  • Notes
  • Published:
Chinese Science Bulletin

Abstract

Geochronological and isotope studies have been carried out for two important plutons in the Central Western Kunlun Belt. U-Pb single grain zircon dating results show that the North Kudi Pluton (404 Ma) was produced near the end of Caledonian; whereas the previously labeled Hercynian Arkarz Mountain Pluton (215 Ma) is either an Indosinian pluton or a product of multiple-phase magmatism. Sm/Nd isotopic data suggest that their sources are quite heterogeneous, and continental crust played an important role during the generation of these two granitic plutons.
