| 英文摘要 | Early investigations on the eclogits across Dabie Mountains identified the eclogites as medium-temperature eclogits, and no other types of eclogites exist. This study discoveries that the eclogites from Leizhuang across Tongcheng area belong to the low-temperature and high-pressure eclogites on the basis of the field trip, petrology and minerals chemistry analysis, thermodynamic appraise. The analysis from the P-T evolution of eclogites distinguish 5 metamorphic stages and show a "hairpin-type" P-T path with increasing temperature (hiring retro-metamorphism. The arrange of I-stage are T = 390 similar to 411 degrees C and P = 0.89 similar to 1.40GPa; II-stage are T = 527 similar to 544 degrees C and P = 1.95 similar to 2.34GPa, which is the peak metamorphism and indicate the most depth of slab subduction; III, IV and V-stage are T = 501 similar to 519 degrees C and P = 1.74 similar to 2.14 GPa, T = 630 degrees C and P = 1.22 GPa; T = 350 degrees C and P = 0.20GPa respectively. A trend of increasing temperature with depressing pressure is confirmed during retro-metamorphism from Ill-stage to IV-stage. The increasing temperature results from the sensitivity of low-temperature eclogite to the temperature variation, the, plentiful supplement of hot from the North Dabie dome and the gradient recovery, when the exhumed eclogitie slab resorts at the some depth of crust. |
