| Abstract | In the last three years new deep heat flow (HF) determinations were made in 100 holes in the north-east part of Ukrainian Shield (East-European platform). The value of Dnieper HF anomaly is determined as 60-65 mW/m2 (background values are 40-45 mW/m2). According to the thermal model the depth of the top border of the partial melting zone of crustal substance is 25-30 km. The top of the asthenosphere is defined by isotherms of 1,200-1,250 0? (50-60 km). The HF anomaly is confirmed by electrical conductivity anomalies in the crust and mantle. |
