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.
