通过对丹东—宽甸东部地区南辽河群中部分岩类的分析，以ＭＯＲＢ型斜长角闪岩进一步证实了太古宙龙岗地块与狼林地块间古洋盆的存在；以大洋环境生成的层状硅质岩、辉长岩、辉绿岩、及堆晶辉石岩的发现，为在该地区继续寻找洋盆收敛、陆陆碰撞的证据——古蛇绿岩残片提供了明确的线索。
Based on the analysis of some rocks in the Nanliaohe Group in eastern Dandong-Kuandian area, the MORB-type amphibolite further confirms the existence of the paleo-oceanic basin between the Archean Longgang block and the Wolfram block. The discovery of layered siliceous rocks, gabbro, diabase, and hectorite also provide clear evidence of the convergence of the oceanic basin and the evidence of continental-continental ophiolitic collisions in the area clue.
