It is shown that one of the most perspective for identification of large-scale endogenous deposits of uranium is the extended zone of the southern frame of the East Siberian plate. With use of the developed earlier evolutionary and geological model of a large-scale uranium rudogenez a number of the concrete areas recommended for carrying out the advancing expected and geological, auditing and search works is allocated. Key words: uranium, mineral resources, rudogenetichesky models, rudoperspektivny areas, forecast, searches. Р. 3-15 |

(Geoelectromagnetic Research Centre IPE RAS) // goidinaa@mail.ru CONSTRUCTION OF THE THREE-DIMENSIONAL CLASTER PETROPHYSICAL MODELS OF GEOLOGICAL MEDIUM BASED ON THE GEOPHYSICAL DATA COLLECTED ALONG REFERENCE PROFILES 3D models of specific electrical resistivity and seismic velocities of the Teelin part of the Altai-Sayan folded area are built based on the geophysical data collected along the reference profiles. It is shown that application of the neural network classification based on the Kohonen self-organizing maps enables to construct a 3D claster petrophysical model of the study area. It is found that the geometry of the anomalous zones in the coordinates’ space is determined by seismic velocities (mainly, by Vs) while the rocks properties and lithology are determined from other geophysical data. The locations of the fracture zones attributed to the Shapshalskii and Kurtushibinskii faulted areas as well as partially melted zones are determined. Keywords: geophysical data, joint analysis, claster petrophysical model, reference profiles, three-dimensional medium. Р. 41-45 |
