Abstract

Present-day tectonics of the Eastern Alps are characterized by strike-slip faulting regime in a complex transition zone between the European, the Pannonian and the Adriatic stress provinces. Evidence can be found for vertical as well as horizontal stress decoupling within the orogen due to a thermally and mechanically weakened crust. Differential vertical uplift derived from repeated precise levellings relative to the reference point in the Bohemian massif is observed in western Austria including the Tauern Window and subsidence in the Vienna basin and in the Styrian basin. We relate this behaviour of vertical motions to the effects of isostatic response to active plate convergence and strain partitioning as well as to rebound in response to Quaternary deglaciation and ice-induced erosion.

Statistical methods of surface evaluation have been applied on the Digital Elevation Model (DEM) to characterize the major domains of tectono-geomorphic units. A remarkable correlation between surface ruggedness and denudation history can be established by combining the DEM-derivatives and fission track data. The domains delineated by low fourth order DEM-derivative values fairly depict areas having paleosurface remnants, while regions characterized by high parameter values typically are areas with high denudation rates in Miocene to Recent time. However, the areas affected by Pleistocene glaciation have specific behaviour.
