Geochemistry, zircon LA-ICP-MS U-Pb ages and Hf isotopes of Hongliugou moyite from north Altyn Tagh tectonic belt

More Information
  • Hongliugou moyite outcropped in western Hongliugou-Lapeiquan complex belt belongs to high K cal-alkaline granites, characterized by SiO2>69.0%, Al2O3>13.0%, (K2O+Na2O)>7.0%, K2O/Na2O>1, 10.4, and hence this age can be regarded as the formation age of the moyite. Combined with regional geological characteristics, the authors consider that the formation of the rock was related to the subduction of the oceanic crust, with the tectonic setting being continental margin arc.
