A Map of the Total Longitudinal Electric Conductivity of the Sedimentary Cover of the Voronezh Crystalline Massif and Its Framing
In the central part of the region, a digital version of the conductivity map of the sedimentary cover. When constructing the S map, electro-prospecting data was used by the VES method. In general, sedimentary rocks are characterized by a large range of variation in the specific electrical resistance (from 0.1 to several thousand Ω m). The values of S vary from Sm units in the VCM territory to the first thousand Sm in the neighboring valleys. In the arch part of anteclise, the values of the longitudinal conductivity are within the first tens of Sm. The increase in conductivity is observed along the Losevskaya suture zone. In the area of transition of the array to adjacent large-scale tectonic structures, the values of S are from 40 to 120 Sm. In the central part of the DDV and RSP, S is equal to 2000 Sm. However, there is an area with S = 3500–4000 Sm.
