Аннотация доклада:
The spatial fields of overlithostatic pressure, the vertical and horizontal stresses in the mantle are studied in 2D numerical model of mantle convection. The model viscosity is temperature-, pressure- and strain-dependent. The typical overlithostatic stresses in the main part of the mantle are in the range of (7 – 9) MPa, with strong concentration in the areas of descending slabs (up to 50 MPa). We find significant differences between the three studied fields.
