Abstract:: Based on the chemical composition and REE data of MORB-type amphibolites from South Liaohe Group in east part of Dandong-Kuandian District, it is proved that there have been a paleoocean basin between Langlin and Longgang Archaeozoic massifs. The discovery of ocean-born gabbroes, diabases and pyroxenites is definite clues to look for more remained pieces of paleoophiolites in this region.
Key words:: paleoophiolites; South Liaohe Group; Dandong-Kuandian
