摘 要: 中国东部及邻区中、新生代大陆边缘的性质,国内外学者论述颇多,众说不一。作者认为它是复合型大陆边缘,其基本特征是:由多个古陆块古陆缘复合,裂解的大陆边缘与增生的大陆边缘复合,安第斯型大陆边缘与阿尔卑斯型大陆边缘复合。还探讨了这一复合型大陆边缘形成的区域构造背景和形成机制。 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.
