通化地区早元古代变质杂岩可划分为集安岩群和老岭岩群。前者遭受了一期四个阶段的进变质作用和三幕变形作用，变质达高角闪岩相；后者主要经历的是一期两个阶段的进变质作用和二幕变形作用，变质达绿片岩相。两岩群变质作用的ｐ－Ｔ－ｔ轨迹都具有逆时针演化的趋势。本区大地构造环境属被动大陆边缘与古岛屿之间内海（边缘海，性质的古拗陷带和裂陷带。
The Early Proterozoic metamorphic complex in Tonghua area can be divided into Ji’an group and Laoling group. The former suffered from a four-stage metamorphism and three-curtain deformation and metamorphosed up to the amphibolite facies. The latter experienced mainly the progressive metamorphism and the deformation of two screens in the first phase and the metamorphic uptakes phase. The p-T-t trajectories of the metamorphism of two groups of rocks all have a counter-clockwise trend. The tectonic environment in this area belongs to the inland sea between the margin of the passive continental margin and the ancient islands (marginal sea, ancient depressions and rifts).
