This paper first reports a high precision U-Pb age of 218+/-1.2 Ma for rutile in coesite-bearing eclogite from Jinheqiao in the Dabie Mounteins, east-central China. This work shows that the U-Pb mineral (rutile+omphacite) isochron age of 218+/-2.5 Ma and conventional rutile U-Pb concordia age of 218+/-1.2 Ma obtained by common Pb correction based on the Pb isotopic composition of omphacite in the same eclogite sample are consistent, proving that the omphacite with low U/Pb ratio (μ=2.8) can be used for common Pb correction in U-Pb dating of rutile. Oxygen isotope analysis of rutile aliquots gave the consistent δ 1 8 O values of -6.1+/-0.1%, demonstrating oxygen isotope homogenization in the rutile of different grains as inclusion in garnet and grain in matrix. Oxygen isotope thermometry yields temperatures of 695+/-35 and 460+/-15 o C for quartz-garnet and quartz-rutile pairs, respectively. These oxygen isotopic observations suggest that the diffusion of oxygen in rutile as inclusion in garnet is not controlled by garnet. According to field-based thermochronological studies of rutile, an estimate of the T c of about 460 o C for U-Pb system in rutile under rapid cooling conditions (~20 o C/Ma) was advised. Based on this U-Pb age as well as the reported chronological data with their corresponding metamorphic and/or closure temperature, an improved T-t path has been constructed. The T-t path confirms that the UHPM rocks in South Dabie experienced a rapid cooling following the peak metamorphism before 220 Ma and a long isothermal stage from 213 to 180 Ma around 425 o C.
