The relevance of the research is caused by the need to improve the efficiency of geophysical methods in the search for gold ore fields, including the use of new methods of geophysical work, electrical tomography VP particularly. Theoretical base, instrumentation, measurement, processing and field interpretation technologies have currently been developed for this method of geoelectric prospecting The main aim of the research is to estimate the informativeness of induced polarization tomography in typical physical-geological environments of Siberian gold ore fields. Objects of the research are opportunities of the electrical tomography during the exploration of different types of gold ore fields. Method of the research is the electrical tomography. Results. It has been found that in ore fields of all physical-geological types, electrical tomography can be used with sufficient assurance to evaluate the thickness and composition of overburden rocks, to locate tectonic faults, to determine the main features of the structural framework of terrigenous-sedimentary rocks in the subsurface horizons, and to make location prognosis for ore mineralization in favourable physical-geological environments. The most informative parameter determined by the data of induced polarization tomography in all types of physical-geological gold ore fields of the Siberian region is rock resistivity, whereas their polarizability is significant, provided that local sulphidization or graphitization of rocks is present.
