%X The detailed study of metamorphism from the original North Jingangku Formation of the Wutai Group indicates three metamorphic evolutionary stages: initial tectonic burial metamorphism (M1) probably related to collision between island arc and continent, subsequent high pressure metamorphism (M2) extending 0.8~1.4GPa down to a depth of 42km from the peak metamorphism in response to crustal tectonic thickening, and isothermal decompression process (M3) as a result of rapid exhumation. A clockwise P T evolutionary path is similar to the P T t path of the typical orogenic belt.
