In the last decades, the tectonic and kinematic evolution of the Mediterranean region have been largely debated. This wide region includes several Permian to Mesozoic rift systems whose architecture were conditioned by crustal-scale shear zones developed in late/post-Variscan times. The polyphase evolution of these basins/crustal blocks is related to the early breakup of Pangea and the opening of the southern North Atlantic, the Alpine Tethys, and the Bay of Biscay, and their subsequent inversion and involvement in the Alpine orogeny during Upper Cretaceous to Cenozoic times. Cenozoic geodynamics led to a disrupted and diffuse Europe-Africa boundary which hampers easy paleogeographic reconstructions. No consensus on the kinematic, main tectonics, deformation history and paleogeography has been reached so far regarding the: 1) relative motions of Iberia and Europe; 2) the southern Iberia boundary and the evolution of the Corsica-Sardinia and the now dispersed AlKaPeCa blocks; 3) the pre-orogenic position and kinematic evolution of the Adria microplate.
We welcome contributions that address the kinematic, tectonic, and geodynamic evolution of prominent geologic features (such as structures, mountain belts, sedimentary basins, microplates, blocks and terranes) that have recorded the past configurations of the Iberia-Europe-Adria-Africa plate boundary(s), from Permian to the present-day. Our aim is to provide firm geological and chronological constraints to unravel the complex evolution of this diffuse plate boundary. We encourage submission of studies presenting new insights derived from different perspectives, including geology (tectonics, stratigraphy, petrology), geochronology, thermochronology, geochemistry, geophysics (paleomagnetism, seismicity, seismic imaging, seismic anisotropy, gravity), and modelling (both numerical and analogue).
