Abstract
One of the key stages of geological exploration is geophysical research. In general, the success of the whole complex of exploration works depends on the effectiveness of their use in most cases.Today, when fields of a very complex geological structure are being studied, the role of geophysical methods is increasingly reduced not to direct searches for ore objects, but to solving problems of searching for various indirect ore-controlling features (analysis of structural-tectonic structure, identification of zonality elements and indirect factors of mineralization control). In this regard, intensive introduction of ore magnetotelluric ore into practice is currently being implemented, which is an effective tool in solving structural mapping and forecasting problems of various types of mineral deposits, especially structurally controlled ones. For efficient use of various technologies of ore electrical reconnaissance, the problem of reconciling the results of electrical soundings with direct current and electromagnetic sounding is very topical. The methods of direct current, have increased sensitivity to objects of high resistance, and allow more correctly determine the boundaries of high-resistance bodies. The main drawback of the methods is the limited depth of research. The depth of magnetotelluric methods is limited only by the recording time at the measurement point. MT parameters have higher sensitivity to conducting objects and are not shielded by high-resistance horizons.A joint analysis of the TDIP and AMT data opens up great prospects for constructing a polarization model at great depths. The integration of two different types of sounding allows solving a wide range of geological problems, from direct search of ore bodies to the identification of indirect ore-controlling features.
