Fission tracks (on apatites and zircons) thermochronological analysis, geomorphological and seismic profile studies are used to understand the evolution, the geometry and the mecanism of recent deformations within european crust (<10 Ma) from the Argentera external cristalline massif to the north-Ligurian margin.First, the denudation of the...

Apatite fission track analysis of samples from the shoulder (marginal ridge) of the Côte d'Ivoire-Ghana transform continental margin reveal a cooling of the margin between 85 and 65 Ma for the central and eastern parts of the ridge. All samples were heated in situ during sedimentary burial with a temperature >120 °C, except for two samples...

This paper presents a combined analysis of geological and geophysical data collected both onshore and offshore along the northwestern Peru forearc area (3°30'­7°30'S), from the coastal plain to the trench axis. Onshore, geomorphic analysis places constraints on the relative importance of eustatic versus tectonic factors in preserving and...

The Oligo-Miocene extension phase of the Mediterranean basins rifting (30–25 Ma) [Jolivet and Faccenna, 2000] followed by the Ligurian basin oceanic crust formation (21–18 Ma) [Le Pichon et al., 1971 ; Réhault et al., 1984 ; Carminati et al., 1998 ; Gueguen et al., 1998] occurred during the western Alps compression phase. The deformations were...
