Zircon U-Pb dating of basement gneisses in the super-large Bayan Obo REE-Fe-Nb deposit, Inner Mongolia被引量：16
《Chinese Science Bulletin》2002年第3期243-247,共5页WANG Kaiyi FAN Hongrui XIE Yihan LI Huimin 
This work was supported by the NationalNatural Sciences Foundation of China; the Science and Technology of Commission of China.
Zircon U-Pb ages have been determined for basement gneisses in the Bayan Obo REE-Fe-Nb deposit. On the U-Pb concordia diagram data of three samples yield up-per intercept ages of 1948-1917 Ma. Thus, these basement gne...
