Abstract: The implication of tectonic cycle in terms of plate tectonics theory is totally different from the one in early knowledge, which laid stress on uncomformity. The picture of tectonics evolution that emerges from the orogeny history study of the Phanerozoic Tethyside system and Precambrian block in Asia is one of a harmony. The continent crust demonstrated an original character of plate tectonics in the earth's early stage. The co-orogeny and post-orogeny deforming show a continuous character. Large-scale strike-slip faults play significant roles in course of tectonic evolution, since they regulate the gradual tectonic progress, and which is identified obviously in Northwest China and Tethyside system. Examining the matter from the view of global tectonics, the concept of orogenic episode is unavailable. The orogeny event, such as Caledonian, Hercynian, and Alpine cycle can't be viewed as a dependent phase in geological succession, since the latter is a continuous one.

Key words: tectonic cycle, homogeneous deforming, plate tectonics, the Tethyside, strike-slip faults
