Research On The Controlled Source Audio-frequency Magnetotellurics And Its Theory Of Formation Identification

Controlled Source Audio-frequency MagnetoTellurics (CSAMT) is an electromagnetic sounding technology of direct detection of underground rock and mineral.Its characteristics are High efficiency, exploration depth range, high vertical resolution, horizontal resolution is high, Topographyis small, high-resistivity layer shielding effect is small, three-dimensional observation.The Controlled Source Audio-frequency MagnetoTellurics and its theory of formation identification is take Western Gold as a background.Concluded from the study Controlled Source Audio-frequency MagnetoTellurics to start.Design simulation of it,Including field source design, measurement methods, the best observation program.research and analysis the data,Calculated Kania resistivity.Simulation of Apparent resistivity sounding curve with the Kania resistivity by Matlab.Research and analysis Apparent resistivity sounding curve,Ground shape come,determine the location and type of ore body.Compared with the known geological data,Illustrate the application of the success and prospects of CSAMT.
