摘　　要：首先对青藏高原分布的蛇绿岩带的地质特征进行剖析，认为这些蛇绿岩是陆内裂谷环境产出的初始洋壳而不是大陆缝合线。然后对喜马拉雅山系的构造特征及其造山体制加以讨论，认为以喜马拉雅山系作为碰撞造山的样板并无地质事实的根据，而是一种想当然的臆说，后来也得不到参验。结论：碰撞造山带在大陆是不存在的，是看不到的。The paper is divided into two parts. The first part analysed the geological characteristics of ophiolite belts distributed on the Tibetan Plateau, and concluded that these ophiolites represent the infant oceanic crust in intra-continental rift environment but not an intercontinental suture. The second part discussed the tectonic features and the mountain building mechanisms of Himalaya range, and considered the using the Himalaya mountain range as a prototype of the collisioned mountain belt has no geological basis and can not be proved by successive geological observation. The conclusion is that the so-called collisional mountain belt doesn't exist or has never been seen in contInent.
