摘要
作者根据最新的科研、区调成果,论述了浙西南下元古界八都群(2050～2400Ma)的建群依据、变质地层、原岩建造、构造序列、变质作用,花岗质岩浆作用,同位素年代及地质意义,认为八都群是我国东南大陆边缘已知的最古老的表壳岩系之一,是中国早前寒武纪陆台的组成部分。
According to the latest research results this paper deals with the grounds for the establishment of the Lower proterozoic Badu Group(2050-2400 Ma), division of metamorphosed strata and protolith formations, structural deformation, metamorphism and granitic magmatism, regional correlation and the geological age and significance. Tt is considered that the Badu Group is one of the oldest supracrustal rock sequences on the southeastern continental margin of China and is a component part of the Early precambrian continental platform of China.
