摘要:
LA-ICPMS Zircon U-Pb Age of the Qingshui Pluton in the East Xiao Hinggan Mountains
      Using laser ablation ICP-MS (LA-ICPMS) technique,the authors obtained a zircon U-Pb age of 222±5 Ma for the Qingshui pluton in the East Xiao Hinggan Mountains. Petrological and geochemical studies indicate that this pluton is peralkaline,belon-ging to A_2 or PA type of post-orogenic setting. It is concluded that the formation of this pluton resulted from the lithospheric extension after the amalgamation of the North China craton and the Siberian craton at the end of Permian.
