Abstract
The energy aspects of the problem of intraterrestrial heat transfer in various forms are discussed. Endogenous causes of conductive heat flow dispersion − radiogenic heat generation, tectonic movements and magmatism (volcanism), including its latent and open discharge in the form of volcanic and hydrothermal activity are considered. The geological ordering of the heat flow in the continental crust is related to convective discharge of the heat and mass flux from the mantle, marked by the isotopic composition of helium in freely circulating underground fluids. The combined transport of heat and helium, as well as the correlation of He isotopic compositions in volcanic and hydrothermal gases and Sr compositions in young lavas, testify to the silicate nature of the heat and mass flow emanating from the mantle reservoirs of different depths.

The energy aspects of the problem of intraterrestrial heat transfer in various forms are discussed
Already the first measurements of temperature in mines showed that the temperature in them all year is invariable and that it increases with depth
The increase in temperature with depth indicated the existence of an upward conductive heat flow (HF), one of the two mechanisms for the removal of intraterrestrial heat
Summary
The energy aspects of the problem of intraterrestrial heat transfer in various forms are discussed. Tectonic ordering of heat flow The measured qs value may differ from its value in the depth because of near-surface factors disturbing the geothermal field.
