Rare metal deposits, spatially and genetically associated with leucocratic and alaskite granites of the Permian age, are confined to their dome parts and apophyses. According to researchers, the formation temperatures of granitoid intrusions are determined within 890-7500C. The actual data indicate that the formation of these deposits is greatlyinfluenced by conductive heat flow from the cooling ore-bearing intrusive massif,leading to redistribution of temperatures in the near-intrusive space, resulting inemergence of temperature fields.Such problems are solved by application of Numerical methods (Marle 9) with use of differential equations, requiring certain initial and boundary conditions. Besides, the following assumptions in the modelling technique are introduced: 1) the mechanism of the melt introduction is ignored; 2) the dominant role of the conductive method of heat transfer over the convective one is allowed; 3) the mathematical model of the thermal field of intrusive bodies in two-dimensional version is considered [1, 2].
