摘要：The faults are basic structural units of lithosphere. They begin to create by the cracking and moving of the rocks because of the gravitation, expansion or compression forces. Two blocks of the rocks are formed, fault walls - hanging wall and foot wall, which are moving along the fault plane. In view of the moving of the hanging wall with respect to the foot wall, we distinguish the normal fault and the reverse fault. In the projection with heights, the normal fault and the reverse fault with two profiles are shown.
