The author found a structure resulting from rotation and shearing at the northern mountain area of Sha Zaoquan in the east of Northern Mountain of Gansu province with interpretion of remote sensing images. The vortical zone and nuclear column of the structure resulting from rotation and shearing were interpreted respectively, based on curvipplonar turns of ridges and drainage system and texture of uniform blocks, and it was demonstrated by ground examination., the nature of the surface of rotation and shearing and the directic,ction of structure resulting from rotation and shearing were definited on the nature of vortical surface. The reason of the structure resulting from rotation and shearing was analyzed further on the composition of volcanic rocks and the distribution of fractures.
