الوصف: Within the complex geodynamic context of the Central Mediterranean, the Adria Plate has played a major role in accommodating convergence between the Africa and Eurasia Plates. Understanding the tectonic deformation history of Adria Plate, which involves the development of the opposing Apennines and Dinarides-Hellenides thin- and thick-skinned fold belts, remains a great challenge. Despite numerous geological and geophysical reconstructions of the Adria Plate, the quantified pre-compressional width and crustal structure are still a matter of debate. To address these uncertainties, we built a regional geological cross-section along a SW-NE transect through the Southern Apennines and Southern Dinarides by integrating published structural cross-sec- tions. Applying the line length method for the cover units and assuming constant area for the basement, we have reconstructed the pre-compressional width of the Adria Plate and its crustal thickness during the Middle-Late Jurassic. The unfolding of the sedimentary cover along the SW- NE cross-section results in an undeformed length, width of Adria, of ~1100 km during Middle- Late Jurassic yielding ~340 km of minimum shortening; ~180 km for the Southern Apennines24 and ~160 km for the Southern Dinarides. We have reconstructed the crustal basement thickness for three different domains along the cross-section: Apenninic Platform-Lagonegro, Apulian Platform-Budva, and High Karst-Jadar Kopaonik, yielding respectively 6, 24 and 22 km. The estimated width of the Adria Plate is smaller than the previously suggested range of 1175 to 167028 km. Nevertheless, our results are consistent with a paleogeographic scenario in which Adria would be partly similar to the Bahamas during the Jurassic where the carbonate factory plays a decisive role. Such scenario is characterized by abrupt platform-basin transitions occurring in narrow zones defined by the Jurassic rifting. Our reconstructed crustal thicknesses are consistent with typical continental crustal thicknesses, although the ...
