In this paper, the author goes into the details of the characteristics which show how the Longxi rotating-rolling tectonic is dictributed. It is believed that this tectonic is distributed among the Qinghai-Xizang massif, the Alashan massif and the Eerduos massif. It may be divided into five cycle tectonic belts. They are the Liupanshan Mountain-the Nanhuashan and the Xihuashan Mountains-the Maomaoshan Mountain, the Xiang shan Mountain, the TanShan Mountain-the Yaoshan Mountain-the Yantongshan Mountain, the Daluoshan and the Xiaoluoshan Mountains and the Qinglongshan Mountain. They congregated to the Guyuan-Baoji area and scattered Northwestward. Two sides of principal cycle surface moved in counterclockwise rotation. This tectonic was clearly shown on the satellite picture and still moves at present. Earthquakes(Ms>7)often depend on it and moves from the outer cycle belt to the inner and the magnitude of these earthquakes is getting greater and greater. The author holds that the formation of the Long ting-rolling tectonic is the result of the movement of the Qinghai-Xizang massif and the Eerduos massif.
