Abstract
Using an optimization method for evaluating the lateral heat source distribution, thermal models for the temperature-depth distribution along the profile Corsica-Leningrad are computed. Comparing with the melting-point curve for dry pyrolite and T/T"SUB m" ratio is evaluated and shows that beneath Central and Southern Europe the temperature is higher than beneath the Precambrian East European Platform From the T/Tm ratio the Nabarro-Herring viscosity is estimated. The results indicate viscosity values in the upper mantle beneath Central and Southern Europe smaller by some orders of magnitude that the values for the East European Platform. -Authors
