SEISMO-TECTONOPHYSICAL MODEL OF THE UPPER LITHOSPHERE

Abstract

The objective of combined seismometric and tectonophysical investigations is to construct the dynamic models of the lithosphere from the study of its deformation elements and to research stress and deformation relationships to wave fields and seismic boundary distributions. Seismo-tectonophysical models bear information about the structure of the lithosphere and the processes forming it. The basis of tectonophysical analyses of seismometric data is notions concerning the anomalous stress state of rock massifs caused by the action of tectonic forces and transference of matter.In the present seismo-tectonophysical model of the lithosphere, a numerous seismic boundaries are attributed to tectonic fractures. Their distribution density in the section depends on the deformation and strength properties of the rock massif. Inversion seismic layers coincide spatially with zones of weakened strength where the tectonic fractures are concentrated.
