Thermal models and standard composition of mantle rocks have been used corresponding to the advection-polymorphous hypothesis. Calculated models are compared with experimental ones, their concordance is demonstrated. The exceptions are the positive anomalies in the experimental data at the depths down to 150-200 km. Perhaps they are connected with the appearance of eclogites in the upper part of the mantle.</a></div> ER -
