ABSTRACT
In this work, three-dimensional models of electrial resistivity, seismic velocity, and density are constructed for the segment of the Earth’s interior in the region of Kuznetskii Alatau, which holds the Sorskoe endogenic copper-molybdenum deposit. By the example of joint analysis of these models it is demonstrated that the probable zones of ore formation and ore deposition are marked by the reduction in the electrical resistivity, seismic P-velocities, Vp/Vs ratio, and density.
Based on the empirical relationship linking the silica content in the rocks with seismic velocities and classification of the rocks in terms of this parameter, the three-dimensional lithological model of the study area is constructed. It can be used as a basis for direct forecasting the copper-molybdenum ore deposits in the region. In particular, the model predicts ore-bearing porphyry granites at relatively shallow depths.
