Using remote sensing (RS) data, the major active faults of the eastern margin of Altai Mountains——the Hovd Fault and the Har-Nuur Fault, are studied, the detailed rupture character is analyzed from a viewpoint of topographic features, and the fault geometry and kinematics characteristics are revealed.

Research on formation period for vertical seal of fractures companied and derived by Surennuoer fault;

Vertical sealing formation period of water leakage path remained by Surennuoer fault and its research significance;

Study on spatial distribution of lateral seal ability of Surennuoer fault;

Spatial distribution of lateral sealing from Shurennouer fault and its control on hydrocarbon accumulation in Hailaer basin;

Time-space distribution of vertical seal in Shurennouer Fault and its relation with oilgas accumulation;

In order to study on the evolution of vertical seal of Surennuoer fault zone ( K1 d1 ) in the north of Wuerxun Depression, the authors analyzed the pressure on the fault surface and mudstone content in the fault zone based on its development and activities.
