Abstract

The Northern Calcareous Alps were rotated 30 clockwise during their history, while the Southern and Central Alps were rotated 50 counterclockwise. The geometry and development of the contacts between differentially rotated units will be investigated, and the timing and reason of rotational movements of the single units. A working hypothesis proposes rotation of single small blocks of the Northern Calcareous Alps between steep sinistral north- east-trending faults in a domino style. The clockwise rotation of the Northern Calcareous Alps can possibly be interpreted as a drag of the frontal part of the anticlockwise rotating Eastern Alpine orogenic wedge on top of the downgoing European plate.
