Heat flow density changes from 35-40 mW/m2 in the south-western part of East-European Craton and the Carpathian foredeep to 50-60 mW/m2 in the Outer Carpathians and to 80-120 mW/m2 in the Pannonian basin. Several levels of thermal field reflect main stages of tectonic evolution and feature of lithosphere structure. High heat flow anomaly was created by Cenozoic geodynamic processes related to collision of the European plate and Alcape microplate.
