|Peculiarities of Ozerninsk rift structure deep structure on the data of complex geological interpretation of geophysical fields|
|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.
