Since the 18th century, many geologists have been working hard to research the geologic movements. They have conducted a great deal of exploration in the field and studied the manner of the tectonic moving mechanics. Their great contribution is the important crystal of geologic development made by mankind. But the manner of geologic movements and its dynamics are under exploration. We can't explain it completely. In this paper the writer will prove the force of moving magma which is an important source of the erogenic movement. The tectonic moving force are of many centres and are not unified. The tidal force, the rotation of the Earth, the continental drift and the plate tectonics etc. originated from the unified. The location of the magma generating may be confined by the quantity of radial materials, by the depth of radial material concentration and by the degree of the fault zone developing. Where the radial materials greatly concentrated is the area of high temperature and high pressure and of strong expanding force. Owing to this expanding force the Earth crust may uplift, but this strong pressure will be reduced if it goes through the fault zone and so the materials in this area may melt into magma. If the magma intrudes into the earth crust where there are not many faults, it may cause epeirogenesis, and on the contrary it may form orogenic zone-upheaval region that expands and compresses the surrounding parent rocks. Because the orogenic zone is the earthquake zone, the volcanic zone, the upheaval region of expanding and compressing the surrounding parent rock, we can conclude in one word: the orogenic zones are the swell scars in the earth crust. The above conclusion can be proved by all information we collected about the orogenic zones in China. Because the orogenic zones are upheaval regions with great bodies and with large heights, and involve many large igneous rock bodies, and are folded, faulted and metamorphosed strongly, and have many overthrusts or unsymmetric folds on its both sides, falling to the outside of orogenic zone, and further from the orogenic zone, these structures may weaken step by step.
