Tectonic models for Adria and the External Dinarides in the context of Jurassic-Cretaceous paleomagnetic results

Adria is a crustal block playing an important role in the geodynamic history of the Central Mediterranean s.l. Recently, a reliable Late Jurassic – Eocene APW path was obtained for its “autochthonous” core. This can serve as a reference frame for describing displacements in its more tectonized margins, like the External Dinarides, where we also carried out systematic paleomagnetic investigation, involving Gorski Kotar and the Velebit Mts from the mainland, several islands of the Northern Adriatic basin, and further in the south, Dugi otok and Vis islands. The External Dinarides have a complicated internal structure. That is why the tectonic models published for the area are diverse. When the different models are inspected in the context of the above mentioned paleomagnetic data, we can conclude that. 1. the Adriatic islands from the Northern Adriatic basin down to Vis island must have moved in close coordination from the Albian on, although some tectonic models place them to different tectonic units. 2. coeval paleomagnetic directions for the Adriatic islands and for “autochthonous“ Adria are co-incident from the late Albian on, thus the paleomagnetic results support the models which regard the former as the imbricated margin of the latter. 3. the Northern Adriatic mainland rotated about 30° CW with respect to Adria, which may be regarded as “inherited” (two carbonate platforms) or may signify relative rotation during Late Eocene between the thrust sheets of the mainland and Adria.
