Abstract

Summary

In the field of modern tectonic stresses, at the intersection of multidirectional faults and faults of different kinematic type, tensile and compression zones arise which are often contrasting in their density properties. The stretching zones should be studied for solving the problems of engineering geology, as well as for searching in an array of rocks of aquiferous areas. Geodynamic (tectonic) stress state of the upper part of the earth crust is manifested by the presence of the main normal stresses, which, as a rule, exceed geostatic stresses from the rock weight. From the perspective of hydrogeology, sections of extension are the most waterbearing; they contribute to the formation of high filtration properties at the local section of rock massif. Modern fulfillment of the complex of geophysical, geodetic, and hydrogeomechanical investigations allows to reveal zones of tension and compression at the stages of prospecting and exploration of deposits. The application of gravity prospecting methods on sections of rock massifs with a known geological structure showed the high efficiency of geophysical methods for detailing the structure of the nodes of tectonic disturbances.
