Basic Role of Extrusion Processes in the Late Cenozoic Evolution of the Western and Central Mediterranean Belts

Tectonic activity in the Mediterranean area (involving migrations of old orogenic belts, formation basins and building systems) has been determined by convergence confining plates (Nubia, Arabia Eurasia). Such mainly accommodated consumption oceanic thinned continental domains, triggered lateral escapes wedges. Here, we argue that implications above basic concepts can allow plausible explanations for very complex time-space distribution tectonic processes study area, with particular regard to development Trench-Arc-Back Arc systems. In late Oligocene lower–middle Miocene, eastern Alpine Tethys domain was caused eastward SE ward migration/bending Alpine–Iberian belt, driven Nubia–Eurasia convergence. The crustal stretching developed wake migrating led Balearic basin, whereas accretionary along trench zone formed Apennine belt. Since collision Anatolian–Aegean–Pelagonian system (extruding westward response indentation Arabian promontory) Nubia-Adriatic domain, around Miocene–early Pliocene, setting central underwent a major reorganization, aimed at activating less resisted shortening pattern, which remnant domains area.
