Abstract
We propose a new procedure for the complex evaluation of thermal properties of rocks based on the data of measurements of the thermal effusivity of samples and the numerical analyses of the volumetric heat capacity according to the mineral composition of the rock. The thermal effusivity is measured under the conditions of periodic heating of the surface of a reference plate operating in contact with the investigated sample. The thermal conductivity and thermal diffusivity are computed according to the estimates of the thermal effusivity and heat capacity. The equations for the errors of the thermophysical analysis are also presented.
