P232 CHANGES OF THERMAL CONDUCTIVITY OF SOME IGNEOUS AND METAMORPHIC ROCKS WITH DEPTH TARAS S. LEBEDEV and VLADIMIR I. SHAPOVAL Institute of Geophysics National Academy of Sciences 32 Palladin Avenue 03142 Kiev Ukraine 1 Results of experimental studies of thermobaric changes of the thermal conductivity coefficient (λ) of some mineral formations of the Central Precambrian Ukrainian Shield with depth are presented and prognostic estimations of its depth distribution are given The thermal conductivity of rocks was studied in laboratory conditions of high themperature (T≤+350°C) and pressure (P≤0.6 GPa). At room and high temperature λ was measured by a standard device
