Paleomagnetic evidence for large en-bloc rotations in the Eastern Alps during Neogene orogeny

The Northern Giudicarie and the Meran-Mauls fault (Alps, Northern Italy) in the light of new paleomagnetic and geochronological data from boudinaged Eo-/Oligocene tonalites

“…It can therefore be assumed that the foliation of the tonalites from the NGF was formed and rotated before the viscous overprint was blocked. The counter-clockwise rotated declinations calculated for the sites along the MMF and NGF are in agreement with Late Oligocene to Middle Miocene data from the entire Southern and Eastern Alps and the internal massifs of the western Alps reported in several studies (see Thöny et al 2006 for a compilation). Whether these NNW-directed declinations are really the results of a *30°counter-clockwise rotation of the whole area in the Late Oligocene to Middle Miocene is topic of ongoing discussion.…”

Reinterpretation of the Ordovician rotations in NW Argentina and Northern Chile: a consequence of the Precordillera collision?

“…Beck et al 1986) or collisional belts (e.g. Thöny et al 2006). Isseven and Tuysuz (2006) describe two models to explain rotational kinematics around vertical axes in the upper crust: continuum (ductil deformation distributed along a wide area) and discrete (rotation of blocks without internal deformation).…”

“…Höckenreiner et al 2003;Dávila 2001). Thöny et al (2006) proposed a rotational domino pattern in the northern Alps generating a mega shear zone along which rotations of near 60°have been determined. Such amount is more likely within a soft domino system instead of the rigid blocks model (Peacock et al 1998).…”

Evidence for Jurassic subduction from the Northern Calcareous Alps (Berchtesgaden; Austroalpine, Germany)

“…North-South geographic directions refer to the Present as a result of a complex rotation history of the Eastern Alps since Late Cretaceous (e.g., Haubold et al 1999;Csontos and Vörös 2004;Thöny et al 2006;Pueyo et al 2007). …”
