TL;DR: The Maghrebian flysch zone was oceanized, at least partially, and acted as a transform fault between the mid Atlantic and the Ligurian ocean, both of them being open at that time.
Abstract: At both ends of the Maghrebides belt, in the Rif Mountains and Sicily, Middle to Upper Jurassic slices of basic rocks with an E-MORB character are associated with various tectonic units of the Maghrebian flysch zone. This zone, which was located between the internal zones, originally linked to the European plate and the African external zones of this Alpine belt, was therefore oceanized, at least partially, and acted as a transform fault between the mid Atlantic and the Ligurian ocean, both of them being open at that time.

TL;DR: In this paper, an apatite fission track thermochronological survey of Corsica was undertaken in order to decipher its Cenozoic thermo-tectonic evolution.
Abstract: An apatite fission track thermochronological survey of Corsica was undertaken in order to decipher its Cenozoic thermo-tectonic evolution. A remarkable geographic zoning of FT ages with a gradient from southwest (older ages) to northwest (younger ones) is interpreted as the result of two major cooling steps, respectively dated at 26–20 Ma and 18–10 Ma. These coolings are attributed to exhumation phases associated with the Oligo-Miocene Liguro-Provencal rifting and the Miocene Tyrrhenian extension, respectively.

TL;DR: The Vazzio basin is a set of continental sedimentary deposits of the torrential type, generally equated to temporary fresh water environments as mentioned in this paper, made up of the Hercynian granitic substratum, which is locally covered by the marly Pliocene.
Abstract: The Vazzio basin (Ajaccio, Upper Corsica) is made up of a set of continental sedimentary deposits of the torrential type, generally equated to temporary fresh water environments. This set of deposits, which rests on the Hercynian granitic substratum, is locally covered by the marly Pliocene. An examination of upper jugal tooth tracks allowed us to identify a specimen of Pomelomeryx boulangeri and thus to date the deposits to the Upper Chattian stage. This mammal was part of the massive invasion of Moschidae in Europe originating from Asia during the Upper/Late Oligocene. The youngest samples correspond to the MN3 biozone. The Corsican specimen examined is morphologically very similar to that of Moissac-II, which corresponds to MP29. Thus, during the Upper Oligocene, the separation of Corsica from the continent was either only partial or very recent.
