New heat flow values for three different geological regions (east Kamchatka, the Baikalian rocky area and the Altai-Sayan folded zone) have been obtained. The ranges of heat flow variations for each region are respectively: 39-66, 38-80 and 34-69 mW/m2 (0.93-1.56; 0.9-1.9; 0.82-1.63 О_cal/cm2 sec). Heat flow anomalies have been established for the east-Baikalian region, 72 mW/m2 (1.7 О_cal/cm2 sec) and the west Trans-Baikalian region, 59 mW/m2 (1.4 О_cal/cm2 sec). A correlation has been established between heat flow and intensity of neotectonic movements for the Baikalian rift zone and the adjoining areas. The higher flow values correspond to the structural elements of the highest activity of Neogene and Quaternary.
