Abstract: There has been much discussion about the nature of Meso-Cenozoic continental margins ineastern China and its adjacent areas but divergent views exist. The authors consider them to becompound-type continental margins. Their basic features are compounding of ancient continentalmargins of several ancient continental margin and the accretionary continental margin and com-pounding of the Andean-type continental margin and the Alpine-type continental margin. The pa-per also discusses the regional tectonic setting and formation mechanism of this compoundingtype continental margin.
