| 英文摘要 | The U-Pb isotope compositions of rutile, omphacite and garnet in the eclogite from the Jinheqiao area in the Southern Dabie ultrahigh-pressure metamorphic zone were analyzed. The consistent high precision U-Pb age (218 +/- 1.2) Ma of rutile in eclogite from the Dabie Mountains was obtained by two ways of isochron and common Pb correction based on the composition of omphacite. This proves that the omphacite in eclogite has a U/Pb ratio (mu = 2.8) low enough to be used for common Pb correction in the analyses of rutile. Under the rapid cooling condition (40degreesC/Ma) the closure temperature for U-Pb diffusion in rutile is about 470degreesC. Thus, this U-Pb age of rutile proves that 218 Ma should be the cooling age of eclogite at 470degreesC instead of the peak metamorpbic age. |
