Abstract

We carried out co-ordinated palaeomagnetic and microtectonic measurements in the Transdanubian Range and in the Mura-Zala basin and palaeomagnetic investigation in Northern Croatia, in the intramontane basins of the Eastern Alps and in the eastern Adriatic coast, representing the foreland (Adria) of the Dinaric nappe system. The results suggest that the mentioned areas took part in a counter clockwise rotation, triggered by the movement of Adria, with respect to European as well as the African plate. This rotation is not dated precisely, but must have occurred in the last 6 million years. Earlier in the Tertiary, the movements of the Transdanubian Range were probably induced by the subduction pull of the European plate: the two phases of counter clockwise rotation due to this mechanism could have occurred simultaneously with those of the North Hungarian Palaeogene Basin (18.5-17.5 and 16-14.5Ma, respectively), but the angles were larger close to the subductions front (Inner West Carpathians and Palaeogene Basin) and smaller further away, like in the Transdanubian Range. The last two phases of the rotation of the Transdanubian Range took place in a stress field characterized by N-S compression and E-W extension (as expected in an area between the converging large plates). Before the third phase of rotation, a significant change is observed in the orientation of the stress field of the Transdanubian Range.
