Effects of Slab Rollback Acceleration on Aegean Extension

Abstract

Aegean extension is a process driven by slab rollback that

Upper plate deformation and trench retreat modulated by subduction-driven shallow asthenospheric flows

“…Our models also support that this extension could relate to a fixed Eurasia upper plate, which is much larger than the individual subduction zones and is fixed relative to the Mediterranean slabs (scenario B). As in model YFDA70 (Figure 6d), trench retreat acceleration during Miocene (Brun et al, 2016) could have been the consequence of the UP extension that was reconstructed in the Aegean subduction zone (e.g. Brun et al, 2016;Tirel et al, 2004).…”

A new approach to the opening of the eastern Mediterranean Sea and the origin of the Hellenic subduction zone. Part 2: The Hellenic subduction zone

“…The amount of extension between the two limits increases from the top to fault F10. This results in a component of dextral shear strain that is absorbed along a few localized faults, such as those proposed by Brun et al (2016) and by distributed clockwise rotation. Note on the bathymetry of Fig.…”

“…A dextral fault, active during the middle to late Miocene, identified by Philippon et al (2012), follows this Mykonos-Samos branch of the detachment and extends farther west toward Peloponnesus. Brun et al (2016) call this fault the Myrthes-Ikaria Fault. They suggest the existence of other similar dextral faults to the south within the Cretan Basin.…”
