Apparent polar wander path for Adria extended by new Jurassic paleomagnetic results from its stable core: Tectonic implications

With the new Jurassic results, an APW is now defined for Adria for the 167-40 Ma interval. It is well constrained for timing of important changes, like the speed and the sense of rotations. This APW suggests that the CW rotation and southward shift changed to the opposite at 155.1 ± 5.3 Ma, signifying a dramatic change in the life of the Neo-Tethys, from opening to closing. The latter is manifested in fast CCW rotation and northward movement of Adria up to 102.9 ± 2.4 Ma and moderate displacements in the same manner in post-103 Ma times. Combined data sets from stable Istria and the foreland of the Southern Alps point to an approximately 15° CW rotation with respect to Africa at the end of the Cretaceous, and an about 25° in the CCW sense, after the Eocene.
