摘要

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.
