The interconnections of geothermal flux and natural radionuclides with internal structure of the Timan-North Urals region

Two lateral systems of geothermal flux isolines stretch out northwestward and northeastward following the structural plan of the Pechora plate and the Urals. Temperature variations along the surfaces of the main internal structural rock associations of the Earths crust and upper horizons of sedimentary cover are possibly caused by the difference in geothermal flux redistribution and also by the rock composition. The relations between radon-222 concentrations and dislocations with breaks including their directions, depth and timing are revealed. An idea that lateral and vertical mutability of geothermal flux reflects the peculiarities of internal structure of the Earths crust and upper mantle of the Timan- North Urals region is proposed and developed.
