Abstract

Simultaneous large–scale tectonic events occurred in a wide area between the anti–Atlas and Adria during the Oligocene and the early Miocene. In the Atlas, extensional structures associated with the late Triassic – early Jurassic formation of the Atlas Rift were inverted by right–lateral transpression, forming a giant flower structure: the modern Atlas mountain belt. In the western Tethyan region, rapid back–arc rifting and spreading occurred along western Iberia, leading to fragmentation of the active margin, accelerated subduction of old Ligurian Tethys attached to Adria, and to the simultaneous formation of the Liguro–Provençal and Algerian oceanic basins. At the same time, spreading rates in the central Atlantic north of the Atlantis FZ increased considerably. It will be proved that such a combination of events was a consequence of geodynamic processes that occurred along the Africa – Eurasia plate boundary.
