Research Area
I am a metamorphic petrologist, specialized on the high-grade metamorphic rocks, such as amphibolites, granulites and eclogites. These high-grade metamorphic rocks, especially of Precambrian age, may hold significant clues about ancient collisional belts. Hence, to unravel the Precambrian tectonics, I combine metamorphic petrology, mineralogy with geochronology and geochemistry.
To understand the metamorphic evolution of the high-grade rocks with time (P-T-t path), I conduct qualitative (field and microscopical studies) and quantitative (thermodynamic modeling and conventional geothermobarometry) analyses coupled with geochronology (zircon and/or in-situ monazite U-Pb dating) and geochemistry (whole-rock, mineral chemical, trace and REE analysis). Ultimately, integrating the results of these analyses will lead to decode tectonic architecture of an ancient collisional belt of Precambrian time.
