| Abstract: | By analyzing the geophysical data of Lanzhou area,the unit zoning was made according to regional gravity and magnetic field,furthermore,the regional faults were distinguished by combining with the information provided by seismic exploration and electrical sounding.Through studying the relation of natural earthquakes to these faults,the typical active faults were recognized from inherited and newborn faults. |
