Reconstruction of pressure-temperature-time (P-T-t) paths and thermal regimes are essential for inferring tectono-metamorphic processes involved in the formation of metamorphic terranes. However, the P-T information, especially the prograde evolution is generally preserved incompletely due to the fast intra-or inter-grains diffusion under high-temperatures. It may result in different P-T path styles (e.g., clockwise or counter-clockwise), consequently leading to variable interpretations on the related petrogenetic processes.
