Abstract: The Liaohe Group, widely distributed in Eastern Liaoning Province, is a set of Paleoproterozoic stratiform meso-epimetamorphic rocks. There exist considerable variations in the characteristics of lithologic association in different places because of the sedimentary facies changes of the initial rocks, as well as the reformation by later metamorphism and deformation. After years of field investigation, the authors approximately divided the Liaohe Group into two districts and four phase sections. The study will hopefully solve the problems of not only the division of stratigraphic sequence and regional comparison for Liaohe Group, but also the contemporary stratigraphic correlation with adjacent areas.
