you are: the Preliminary card of a thermal stream gretsii

The increase in a thermal stream in a direction from the Mediterranean arch to a volcanic arch in a southern part of Aegean sea, as well as other geophysical features of this area, well speaks subduktsiej the Mediterranean block litosfery which represents the advanced part African litosfernoj plates, under the Egejsky block litosfery, being a part of the Euroasian plate.

In process of immersing the African plate initiates ascending movements of hot substance in that volume of a cloak which is over a falling plate and under the South Egejsky rear arch. This effect can be caused frictional heating of a surface of a roof of a plunging plate, the hydrodynamic forces arising at its immersing, or magma generation in bowels. In development of ascending movement of hot substance the important role plays, apparently, degidratatsija an oceanic bark.

Ascending movement, most likely, has the form konvektsii. Thanking konvektivnym to the streams raised thus, or thanks to volume increase mantijnogo a material over a plunging plate the South Egejsky block rear ostrovoduzhnoj litosfery is stretched and breaks. It explains increase in a thermal stream in a southern part of Aegean sea and in southwest Turkey.
