This paper analyses the relationship of important tectonic motions to magmatic response events in Qinghai Tibet Area. The results show that with the migration of tectonic motion from north to south, and the development of different Tethys stages also show the same changes; meanwhile, the evolutions of magmatic response events are from ultrabasic/basic to acid, alkaline, and eventually, these events are characterized by the occurrence of high potassium igneous rocks series in opistho Tethys stage. After undergoing the tectonic motions and butt jointing of south north continent in Tethys stages, the collision between continent and continent in Upper Cretaceous period and Eocene epoch, the formation of plateau rudiment in Oligocene epoch and Miocene epoch, and the intra continental deformation of rapid uplifting since Pliocene epoch, the geomorphic landscape of "high massive flattish" Qinghai Tibet Area is formed.
