The western end of the Tauern window is marked by what we refer to as the Brenner Normal Fault Zone. The Brenner Fault—since the late eighties—is known as a textbook example of a normal fault. Already in (1934), Dunner proposed west-directed normal faulting related to updoming of the footwall (i.e. the Tauern window). These earlier publications (e.g. Schmidegg 1953) mainly focussed on a brittle normal fault known as Silltal Fault that represents a northern segment of the Brenner Normal Fault Zone. Behrmann (1988) and Selverstone (1988) were the first to also describe ductile components of normal faulting in an area further south, referred to as Sterzing-Steinach mylonite zone (Behrmann) or Brenner line (Selverstone). In (1997), Fugenschuh et al. presented a two-stage model for the evolution of the Brenner Normal Fault Zone. Thereby ductile normal faulting was restricted to an area between Sterzing and Matrei during stage 1 (referred to as Brenner Normal Fault s.str. in this contribution), while brittle faulting during stage 2 not only overprinted the earlier mylonites of the Brenner line s.str. but extended further north into the entirely brittle Silltal Fault. This model involved coeval N–S compression and E–W extension during stage 1. The published calculated total amounts of related E–W extension, derived from metamorphic data and distinct exhumation histories in footwall and hanging wall and from the estimated dip of the overall fault zone, varied significantly between 10 and 20 km (e.g. Behrmann 1988) and up to 70 km (e.g. Fugenschuh et al. 1997). The contribution of exhumation by erosion as a consequence of coeval N–S compression has never been explicitly considered and calculated so far.
