TL;DR: In this paper, the authors explore the geology of the Aegean region in the Miocene to identify the geological signature of a first-order slab tear observed in all tomographic models.

TL;DR: In this paper, a 3D thermo-mechanical numerical joint model of continental collision, oceanic subduction and slab tearing is presented, which allows self-consistent reproduction of first-order Tethyan tectonic structures such as back-arc rifting and large-scale strike-slip faults accommodating continental escape.

TL;DR: In this paper, the authors used stratigraphic, petrologic, metamorphic, structural, paleomagnetic and magmatic data to build new kinematic reconstructions of the eastern Mediterranean region since the late Cretaceous using the principle of non-rigid domains.

TL;DR: In this paper, the authors use a 3D high-resolution petrological and thermo-mechanical numerical model to quantify the relative contribution of oceanic and continental subduction/collision, slab roll-back and tearing to magma genesis and transport processes and suggest that the space and time distribution and composition of magmas in the overriding plate is controlled by the 3D slab dynamics and related asthenospheric flow.

TL;DR: In this paper, the authors suggest that alternating extension and compression in Africa could be explained by switching convection regimes, with the extensional situation correspond to steady-state whole-mantle convection, Africa being carried northward by a large-scale conveyor belt, while compression and obduction would occur when the African slab penetrates the upper-lower mantle transition zone and the African plate accelerates due to increasing plume activity, until full penetration of the Tethys slab in the lower mantle across the 660 km transition zone during a 25 Myr long period.
