Abstract

According to the classical theory of isostasy topography is controlled by the variations of crustal thickness on a regional scale because the crust floats on the mantle. However, the existence of over- and undercompensated areas indicates that the classical isostatic theories are not enough to explain the topography. Mounting evidence indicates that a significant proportion of Earth’s topography results from the viscous stresses created by flows within the underlying mantle. This portion of the topography is commonly referred as dynamic topography. In a case study on the European continent I analyzed the coherency between topography and free-air anomaly and it was found that dynamic topography may play an important role in the Pannonian basin.
