After continuous discoveries of high-pressure and ultra-high pressure metamorphic assemblages in the Dabie-Sulu area,the issue of the Dabie-Sulu orogenic belt extending eastward to the Korean Peninsula has been paid attentions widely. The discoveries of eclogites in the Hongsoeng area,the middle-western Korean Peninsula gives rise to the debate on the tectonic affiliations of the southern massifs. Although the Rimjingang belt in the Korean peninsula has been well investigated,the relation and comparative study to the Dabie-Sulu orogenic belt are lacking of detail work. In this paper,on the basis of informations and results of our previous works,some new contrastive considerations on the correlation between the Dabie-Sulu orogenic belt in central-eastern China and Rimjingang belt in the Korean Peninsula have are provided.展开更多
