内蒙古东北部及周边地区前中生代构造发展演化史

内蒙古东北部地处西伯利亚板块南缘，南与中朝板块相邻。元古代—古生代期间历经西伯利亚板块的向南增生、地体拼贴、“中东亚洋”关闭和西伯利亚－中朝板块的对接碰撞形成统一欧亚板块等一系列构造事件，形成规模巨大的兴安－内蒙古地槽褶皱系（大陆边缘造山带）。中新生代主要受欧亚板块和太平洋板块运动的影响，表现为陆内造山作用，形成三种性质不同的叠合盆地。

THE TECTONIC EVOLUTION OF THE NORTHEAST OF NEI MONGOL AND ITS ADJACENCY IN PRE MESOZOIC ERA

The northeast of Nei Mongol is located in the fringe of the Siberia plate and adjacent to the Sino Korean plate. After accretion of the Siberia plate southwards, amalgamation of terrene, the close of the middle East Asiatic ocean, the collision of the Siberia plate with Sino Korean plate and the formation of the unitary Eurasian plate, the enormous Hinggan Mongolia geosynclinal folded system (Continental margin orogenic belt) was constituted. Under the influence of the Eurasian plate and Pacific plate movements, the interior orogeny took place and three different kinds of basins overlaid and formed the superposed basin in the northeast of Nei Mongol and its adjacency.
