Terra Nova, 00, 1–11, 2011AbstractA palaeomagnetic study carried out at 33 geographically distributed localities in the Miocene fill of the 600‐km‐long Moravian and Polish segment of the Carpathian Foredeep revealed an overall more than 20° CCW rotation of the area. These new palaeomagnetic results can be best interpreted in terms of CCW rotation starting at around 17 Ma. The rotations must have affected not only the sedimentary fill of the Carpathian Foredeep but also the basement, owing to the dextral shift on NW–SE trending block‐bounding faults observed in the basement and in the Miocene sediments. This evidence for `non‐European' palaeomagnetic directions north of the Alpine–Carpathian mountain chain together with previously published indications question the rigidity of the European plate during the last 20 Ma, at least near the thrust front of the Alps and Carpathians.
