Abstract

The temperature model of the lithosphere along transect II passing through
the Western Carpathians and the Pannonian Basin has been calculated using 2D integrated
geophysical modelling methodology. Based on the extrapolation of failure criteria,
lithology and calculated temperature distribution, we derived the rheology model of the
lithosphere in the area. Our results indicate a decrease of the lithospheric strength from
the European platform and the Western Carpathians towards the Pannonian Basin. The
largest strength can be observed within the upper crust which suggests rigid deformation
in this part of the lithosphere. In the lithospheric mantle, strength almost disappears
which allows us to assume that the ductile deformation dominates in this part of the
lithosphere.
