Abstract
This paper discusses the results of our comprehensive studies of the temperature-baric dependences of the effective thermal conductivity of granites. For a detailed analysis, we selected some published experimental results of the temperature and pressure dependences of the effective thermal conductivity of a number of granites (as well as granitoids) in the temperature and pressure ranges of ~273– 900 K and 0.1–1500 MPa, which corresponds to the parameters of rocks from the surface layer to depths of more than 50 km of the continental crust. A low-parametric description of the temperature-baric dependence of the effective thermal conductivity is proposed, which is in good agreement with the experimental data, at least in the temperature range of ~273–600 K, in the absence of irreversible changes in the samples as a result of the thermobaric effect.
