A method of model calculations for the approximate estimation of the emplacement depth of magmatic intrusive body based on data for the distribution of isotherms in the near-intrusive area is proposed. Isotherms are maximums of respective temperatures reached when exocontact rocks are heated at a different time; some of them represent isogrades. The calculations require knowing the form of the intrusive body, the magma composition and initial temperature, the regional geothermal gradient in the Earth’s crust during the magma intrusion, the thermal and physical properties of rocks and melt, and the distribution of isogrades/isotherms in the enclosing rocks. The probable depth of emplacement of the Kharlovo gabbro massif in the northwestern foothill belt of Altai is estimated as an example. It was determined to be 7–8 km. The estimates of depth that are obtained in such a way cannot be absolutely accurate, since they are a result of calculations in a simplified model statement.
