Abstract: | As the members of Chinese Group of the international cooperative project of "Mineral Resources, Metallogenesis,and Tectonics of Northeast Asia", the authors had the opportunity to review the recent achievement of regional geology in this area. This paper is confined to a brief discussion of the nature, composition and evolution of terranes in a part of Northeast China. Nine terranes were recognized. A splicing pattern of when and how the amalgamation of 9 terranes into one microcontient is proposed here. |
