| 英文摘要 | The zircons from gneisses in high and ultrahigh-pressure (HP-UHP) metamorphic zones of the Dabie Mountains have been investigated by using Laser Raman microprobe analysis, cathodoluminescence (CL) images, U-Pb ages and trace elements measured by LA-ICP-MS. Most of the FWHMs (full widths at half-maxmum) of 1008cm(-1) band of zircons are less than 20cm(-1) suggesting that zircons are well crystallized to moderately damaged. The early inherited zircons from gneisses bad undergone significant annealing and recrystallization during the HP-UHP metamorphic event. The a-doses that zircons suffered are probably accumulated from about 200Ma, indicating that HP-UHP metamorphic rocks have been exhumed to the Surface of the earth at this time. The magmatic events of Cretaceous age in North Dabie may exert little effect on the HP-UHP rocks, which most of FWHMs and frequencies of zircons in Dabie Moutains fall into the natural radiation damage trend (RDT), indicating completely recrystalization of zircons during the HP-UHP metamorphic event. |
