It is revealed the anomalies of high electrical conductivity with electrical resistance 2-250 Ohm·m in the crust, which coincide with the deep fault zones and to the depths of 2,5 km are subvertical structure and deeper - mainly subhorizontal layers. According to the results of three-dimensional modeling, the Tarasivka structure is fragmentarily manifested as a low resistivity, the conductive zones with different resistivity cross it in a sublatitudinal direction, in which the lowest values from 10 Ohm·m in the south to 100 Ohm·m in the north are in its contour. In the vertical section it can be represented in as several layers: the first one is the conductor with, most likely linked not only with high electrical conductivity of surface sediment deposits, but also with the zones of disintegration of rocks of the basement; the second one is a high resistivity layer with, possibly it is represented by the uniform non-differentiated thickness; the third layer is the electrical conductor with, probably linked with the special composition of the earth's crust at these depths (graphitization, sulfidization, etc.) or fluidization of different origins. In general for Golovanivsk suture zone the low resistivity anomalies are confined to the alongated strips and areas of the spread of the graphitized rocks and metasomatic zones extended along the fault zones. In its boundaries there are a large amount of the ore deposits of the region. Product Description popup.authors Ільєнко Володимир Анатолійович Ніколаєв Іван Юрійович popup.nrat_date 2020-04-02 Close
