Eight aspects related to the study of Early Precambrian metamorphic stratigraphy are dealt with in this paper: general situation of the study; complexity of the stratigraphy and difficulties of the study; thoughts and methods of the study; division of rock suite, rock group and complex rock; researches on important regional discordances; types and characteristics of protolith and recovery of palaeoenvironment; correct differentiation of the metamorphic strata, TTG rock system and other metamorphic plutonic rocks; determination of the ages of the metamorphic strata. In addition, three suggestions are put forward for future work.
