TLDR
This paper assess the consequences of these collision ages on the magnitude and location of continental consumption by compiling all documented shortening within the region, and integrating this with plate kinematic reconstructions.Abstract:
The Arabia-Eurasia collision has been linked to global cooling, the slowing of Africa, Mediterranean extension, the rifting of the Red Sea, an increase in exhumation and sedimentation on the Eurasian plate, and the slowing and deformation of the Arabian plate. Collision age estimates range from the Late Cretaceous to Pliocene, with most estimates between 35 and 20 Ma. We assess the consequences of these collision ages on the magnitude and location of continental consumption by compiling all documented shortening within the region, and integrating this with plate kinematic reconstructions. Shortening estimates across the orogen allow for ~350 km of Neogene upper crustal contraction, necessitating collision by 20 Ma. A 35 Ma collision requires additional subduction of ~400‐600 km of Arabian continental crust. Using the Oman ophiolite as an analogue, ophiolitic fragments preserved along the Zagros suture zone permit ~180 km of subduction of the Arabian continental margin plus overlying ophiolites. Wholesale subduction of this more dense continental margin plus ophiolites would reconstruct ~400‐500 km of postcollisional Arabia-Eurasia convergence, consistent with a ca. 27 Ma initial collision age. This younger Arabia-Eurasia collision suggests a noncollisional mechanism for the slowing of Africa, and associated extension.read more

TL;DR: It is shown that using a mantle reference frame, which defines plate positions relative to the mantle, instead of a paleomagnetic reference frame may introduce errors in paleolatitude of more than 15° (>1500 km), because mantle reference frames cannot constrain, or are specifically corrected for the effects of true polar wander.

Earth History and Palaeogeography
TL;DR: Using full-colour palaeogeographical maps from the Cambrian to the present, this interdisciplinary volume explains how plate motions and surface volcanism are linked to processes in the Earth's mantle, and to climate change and the evolution of Earth's biota.

Origin and consequences of western Mediterranean subduction, rollback, and slab segmentation
TL;DR: In this article, the authors address the questions of what caused Oligocene rollback initiation, and how its subsequent evolution split up an originally coherent fore arc into circum-southwest Mediterranean segments.

Mediterranean extension and the Africa‐Eurasia collision
Laurent Jolivet,Claudio Faccenna +1 more
TL;DR: A number of tectonic events occurred contemporaneously in the Mediterranean region and the Middle East 30-25 Myr ago as discussed by the authors, which are contemporaneous to or immediately followed a strong reduction of the northward absolute motion of Africa.

TL;DR: In this paper, the main Zagros orogen is shown to be deeply rooted, possibly to Moho depths, and the suture zone effectively runs along the MZT.

TL;DR: In this paper, the authors presented a synthetic view of the geodynamic evolution of the Zagros orogen within the frame of the Arabia-Eurasia collision, and provided lithospheric-scale reconstructions of the zagros Orogen from ~ 150 to 0 Ma across two SW-NE transects.
