摘　　要：江西婺源地区中元古代变质岩类型以浅变质的板岩、千枚岩、变余火山-碎屑岩及变火山熔岩和变质较深的构造片岩组成。根据岩石化学特征、变质作用类型和地质构造活动,恢复其原岩为一套泥质沉积和火山岩。中元古代地层发生区域变质的主要时间为晋宁期。The type of metamorphic rocks in wuyuan area of jiangxi province is composed of shallow metamorphic slate, phyllite rocks, and variable volcano-clastic rocks, as well as deep tectonic schist. According to the petrochemistry character, metamorphism type and geological structure activity, the original rock was restored as a set of mud sediments and volcanic rocks. The main time of the metamorphism in the mesoproterozoic stratum is the jinning period.
