英文摘要	Cathodoluminescence (CL) imaging and ion microprobe (SHRIMP) U-Pb dating were carried out for zircons from eclogites in the North Qilian Mountains. The results show weighted mean ages of 463 +/- 6 Ma and 468 +/- 13 Ma for two samples, respectively. These ages are the earliest record of Caledonian high-pressure metamorphism in the North Qilian Mountains, and they may represent the timing of eclogite-facies metamorphism when the oceanic crust was subducted to mantle depths in this orogenic belt.; Multidisciplinary Sciences; SCI(E); 43; ARTICLE; 8; 848-852; 49
