The results of studying the Early Paleozoic rift structure with using a scientific-methodical approach including the means of geological-structural analysis and the different ways of geophysical information processing and interpretation are given. An analysis of some methods of solving the inverse problem of magnetometry and gravimetry is presented. It showed the high informativity of the method of selecting the particular points of a magnetic field by means of calculating an analytical signal and the method of «wavelet-transformation» of a gravitation field. Using these techniques of processing the data of survey of potential fields, with taking into consideration the parameters of well studied natural analogues, allowed to determine the deep regularities of bedding of volcanic-sedimentary deposits within the rift structure. This technique is topical for establishing the prospective petroleum accumulation zones in the districts difficult of access for seismic survey works.

Key words: Ozerninsk rift structure, deep structure, inverse sum of gravity-and magnetic survey, audio magnetotelluric sounding, Eastern Siberia.
