| Description |
The physical properties of petrographic varieties of granitoids of the Kola Peninsula have been considered. Experimental data on the mineral composition and physical properties of rocks (density, elastic modulus, Poisson's ratio, compressive strength, longitudinal wave velocity) that make up the rock complexes of the Murmansk block – granodiorite and alaskite granite – have been presented. To assess the thermophysical properties of rocks under normal thermodynamic conditions, the relationships between the parameters of the properties and their mineral composition have been used. Based on this approach and the temperature dependence of the properties of rock-forming minerals, a theoretical assessment of the effect of the thermal factor on the physical properties of granitoids (thermal conductivity, specific heat capacity, elastic modulus, coefficient of linear thermal expansion) have been carried out. The results of predicting changes in rock properties under elevated temperatures in the range from 20 to 100 °C have been presented.
