isotopic age

Through an integrated analysis of the types of tectonic deformation and metamorphism, order of their formation, emplacement of plutons and isotopic age data, this paper discusses the regional distribution and formation ages of metamorphic rocks and their role and significance in the process of crustal evolution.
