| 英文摘要 | Petrological and mineralogical data from the Jinheqiao eclogite recorded a five-stage metamorphism, with the first stage being the peak metamorphism and others the retrograded metamorphism. On the basis of the minerals compositions analysis, appropriate thermobarometries are applied to estimate P-T conditions for different metamorphic stages. The first stage: T = 797 degrees C and P = 3.50GPa; the second stage: T = 667 degrees C and P = 2.72GPa; the third stage: T = 660 degrees C and P = 1.50GPa; the fourth stage: T = 616 degrees C and P = 1.10GPa; the fifth stage: T = 450 similar to 550 degrees C and P = 0.40 similar to 0.70GPa. Combined our petrological P-T path and the geochronological T-t path published recently, a precise P-T-t path can be established, which is composed of four sections, i.e., fast decreasing of T and P -> very fast decreasing of P isothermally -> faster decreasing of T and P -> slow decreasing of T and P, and reflects four exhumation progresses form 115 kilometers depth. |
