Scientific paper

A map of heat flow in Europe and diagrams showing the distribution of conducting objects in the Earth's crust and upper mantle and the gravitational effect of the European mantle were used with information from deep seismic sounding and the patterns of distribution of the velocities of seismic waves in the European mantle to construct geophysical models in accordance with the polymorphous-advection hypothesis of deep processes. It is shown that the last period in the geological history of Europe is characterized by activation of its southern and western parts, expressed in the formation of deep depressions, different types of fault-magmatic activation and epiplatform orongenesis. These processes are accompanied by anomalies of the heat flow, gravity and other fields of a mantle nature. There has been a substantial reduction in crustal thickness in the southern and western parts of Europe where a process is transpiring which, in the not distant geological past, ended in an oceanization process.
