Abstract In collision belts, the first-order role of mantle in localizing deformation has remained elusive, as resolution geophysical imaging remains too low to constrain crustal geometry. To address this issue, we geologically interpret a recent high-resolution shear-wave velocity model from ambient-noise tomography Western Alps. We show that lower Alpine geometry is highly variable at depth, evolving preserved European slab South smooth root North. Moho morphology controlled by numerous...
Abstract The Variscan and Alpine long‐term thermal evolution of the European paleomargin in external Western Alps is still unknown, although important for reconstructing geodynamic this orogen. Here we combine zircon fission track apatite U‐Pb double dating analyses Pelvoux massif Alps. Apatite ages <310 Ma >320 define a bimodal age distribution that reflects differential cooling across East Shear Zone. QTQt history modeling reveals two‐stage rifting on paleomargin, initiated with...
Constraining quiescence intervals in tectonically active regions remains challenging, particularly tectonic reconstructions, as these periods are often overprinted by extensional and/or compressional processes that remobilize geological materials, rendering access and dating of difficult.Recent studies stable on laterites bauxites formed through weathering under tropical climates have demonstrated the efficacy (U-Th)/He geochronology Fe-oxyhydroxides (hematite goethite) constraining...

Lithospheric delamination involves short-lived crustal and surface responses, alkaline magmatism, high heat flow extension. In the Western Mediterranean, is hypothesized to have triggered uplift at origin of Messinian Salinity Crisis (MSC). But as primary cause questioned due insufficient temporal resolution. We report new U-Pb ages clumped isotope analyses from calcite veins formed in an eastern Betic intramontane basin. They reveal a brief fluid event 8.5 5 Ma linked extension retreating...
Constraining the relative roles of erosion and tectonics in evolution mountain belts is a challenging scientific goal. In this review article on Western Alps, we show how it becomes possible to “bridge gap” between long–term (>Ma) orogenic controlled by exhumation processes recent geomorphological that accessible an annual–decadal basis. Advances mineral dating have grown relation deformation ductile brittle crustal fields allowed us constrain through time depth. A drastic change from...
The Alpine orogenic belt in SE France is the result of collision between European, Adriatic and Iberian plates. accreted Variscan continental crust, which now forms external crystalline massifs (ECMs), recorded a complex Mesozoic thermal tectonic evolution, that not fully understood. In Maures-Tanneron massif (MTM), basement has undergone periods subsidence uplift, latter indicated by stratigraphic gaps from Albian Upper Turonian to Maastrichian. Ecrins-Pelvoux (EPM), differential documented...
Recent ambient noise Vs tomography data at the scale of Western Alps (Nouibat et al., 2022) highlight deep structure chain. In European foreland, seismological model shows a crust normal thickness, with slow velocities (
It is now well established that the tectonic structure and thermal properties inherited from orogens rifting play an important role in subsequent collision. This study focuses on inheritance of crystalline massifs SW Alps (Pelvoux Maures-Tanneron) their geodynamical implications during Mesozoic continental rifting.

The Alboran margin in the Betics formed as a result of backarc crustal thinning oblique to direction slab retreat. history sediment infill, subsidence and faulting reveals extension at upper levels operated from Serravallian-early Tortonian late (14-8 Ma) synchronously with Ca-K magmatism. Only recently, around 8 Ma, retreating detached resulting onset tectonic inversion margin.

Abstract Lithospheric delamination involves short-lived crustal and surface responses, alkaline magmatism, high heat flow extension. In the Western Mediterranean, is thought to have triggered uplift at origin of Messinian Salinity Crisis (MSC). This scenario questioned by insufficient temporal resolution relative other proposed mechanisms that include shortening slab detachment. Here, we report new U-Pb ages clumped isotope analyses from calcite veins formed in an intramontane basin eastern...
