Abstract:

Magneto-Telluric method is one of the effective tools for mineral prospecting and deep structure investigation. However, with the complex geological environment, which has several adjacent anomaly sources, in many cases apparent resistivity curve is not allowed to locate the specified objects. In this article, the authors has built a procedure to transform the observed magneto-Telluric data into the differentiated one. The use of the differentiated curve instead of the apparent resistivity curve showed an improvement of the resolution and locality for both theoretical data from models and the field data. On the survey profile at the area of Southern Thanh Hoa province, where has several nearby faults, the geological structure under the profile was verified by combining the results from differentiated processing and 2D inversion of the magneto-Telluric data
