Abstract: The present paper deals, on the basis of plenty of the data from the field observations and laboratory studies, with the types and characteristics of the Early Palaeozoic sedimentary suites on the North China platform with the aid of the basic theory and method of the sedimentary suites. Eight types of the sedimentary suites and two types of sedimentary suite series have been distinguished in the light of the paragenetic associations of the rocks, and two types of stratigraphic framework and geometry have been recognized in the inner and marginal regions of the platform. The evolution of the North China platform in the Early Palaeozoic may be divided into four stages which not only reflect the sedimentary and tectonic history, but also are of theoretical value for the study of the Palaeozoic strata on the platform.
