During the Oligocene, in the central western Alps, tectonic accretion of the external domain to the internal orogenic wedge along the Briançonnais Frontal Thrust (BFT) was followed by backfolding, resulting in the Alpine fanning structure. The Briançonnais fan axis was rapidly exhumed by erosion. This growing wedge at the scale of the entire...

During the Neogene, the internal arc of the Western Alps underwent extension behind its inverted Paleogene frontal thrust while shortening affected the external arc. In the core of the internal arc, doming of eclogite-bearing gneissic nappes has formed the Dora–Maira massif. The blueschist-bearing Schistes lustrés of Queyras, which overlie the...

The contrasted seismotectonic regime of the Western Alps is characterized by radial extension in the high chain, combined with local compressive areas at the foothill of the belt, and everywhere occurrence of transcurrent tectonics. Here, we compare this seismotectonic regime to a large-scale compilation of GPS measurements in the Western...

We investigate how focal solutions and hypocenter locations may depend on the ray tracing algorithm and the strategy of velocity inversion. Using arrival times from a temporary seismological network in the south-western Alps, a local earthquake tomography has been performed by Paul et al. [Paul, A., Cattaneo, M., Thouvenot, F., Spallarossa, D.,...

In this contribution, we synthesize recent geological works undertaken on Terre Adélie during the GEOLETA and ArLita programs. The Terre Adélie Craton displays a long geological history emphasized by 2 high grade metamorphic events during the Neoarchean (2.6-2.4 Ga, M1) and Paleo-Mesoproterozoic (1.7-1.5 Ga, M2). Some greenschist facies sheared...

The dating of the uplift onset of the Mongolian mountain ranges, the northernmost relief associated with the India-Eurasia convergence, is a fundamental issue to better understand the mechanisms of propagation of the Cenozoic transpressive deformation in Central Asia. Using apatite fission tracks we determined the timing and strain rates of the...

We report apatitefission-track and10Be terrestrial cosmogenic nuclide (TCN) dating of14 moraine boulders originating from inland Terre Adélie, East Antarctica. These data show coolingof the Proterozoic Terre Adélie craton at <∼120°C between 350 and 300 Ma, suggesting > 4 kmtemperate glacial erosion during the Late Palaeozoic Ice Age, followed...
