内蒙古地域辽阔，全区跨越了西伯利亚、华北、哈萨克斯坦、塔里木四大板块。受多期构造运动影响，地质构造环境极其复杂。历年来关于华北板块、西伯利亚板块缝合带界限的位置，始终是地质工作者讨论的热点。笔者从地球物理学的角度，分析了华北板块与西伯利亚板块缝合带之地球物理场（重磁场）特征，认为西拉木伦河断裂带应是华北板块与西伯利亚板块的终极缝合带。

Inner Mongolia has vast territory and, according to the theory of plate tectonics, strides across Siberian, North China, Ka-zakhstan and Tarim plates. Its tectonic environment is extremely complex in that it has experienced multi-period structural movements in geological history. For years, the boundary between North China and Siberian plates has been a discussion hotspot among geologists. Based on an analysis of the geophysical gravity and magnetic field characteristics of the suture zone, the authors hold that Xar Moron River fault zone should be the ultimate suture zone between North China and Siberia plates. The results obtained by the authors provide geophysical evidence for the determination of the ultimate suture zone between the two large plates.
