GEOPHYSICAL APPLICATIONS OF THE RESULTS OF A PT-STUDY OF ELASTIC PROPERTIES OF ROCKS

Abstract

The study of samples from collections from one of the geological provinces of the Ukrainian shield that formed under different pressures and temperatures revealed a clear-cut connection between distribution features of elastic characteristics of a number of minerals and their geostructural nature. We found that rock elastic parameters may serve as a diagnostic indicator of the presence of a fault-block structure near the zone of a deep fault confining considerable inhomogeneities in stress and heat field distributions. The analysis of all geologo-geophysical information and the results of a PT-study of physical parameters of the rocks along a section of the deep seismic sounding profile served as a basis for the development of the method and a version of the velocity profile in the upper lithosphere that would undoubtedly complement seismic data.
