摘要
<正>An integrated study of petrology,whole-rock and Sr–Nd isotope compositions,combined with zircon U–Pb ages and Hf isotopes,for the Wudaoliang diorites from the Hohxil area,northern Tibet provides constraints on the genesis of intermediate magmas and insights into the origin of high-Mg# andesitic signature of the continental crust.LA-ICP-MS zircon U-Pb dating indicates that the Wudaoliang diorites were generated in
