Abstract
Summary
The article discusses the informativeness of advanced geophysical studies, according to which the small-block structure of the geological section of the territory was identified. At the base of the geological section, are lying the Precambrian crystalline rocks, which are significantly different in the magnitude of the resistivity, from 780 to 50000 Ohm, and by the values of the velocity of refraction waves from 2.7 to 7.0 km/s.
A wide range of changes in the geophysical characteristics of the basement rocks indicates significant changes in the degree of fracturing and weathering of crystalline rocks, which should be taken into account when drawing up a master plan for the location of HPP facilities.
