Ivrea mantle wedge, arc of the Western Alps, and kinematic evolution of the Alps–Apennines orogenic system [PDF]
Swiss Journal of Geosciences, 2017 The construction of five crustal-scale profiles across the Western Alps and the Ivrea mantle wedge integrates up-to-date geological and geophysical information and reveals important along strike changes in the overall structure of the crust of the ...

Receiver function mapping of the mantle transition zone beneath the Western Alps: New constraints on slab subduction and mantle upwelling [PDF]
Earth and Planetary Science Letters, 2022 International audienceTo better constrain the deep structure and dynamics of the Western Alps, we studied the mantle transition zone (MTZ) structure using P-wave receiver functions (RFs). We obtained a total of 24904 RFs from 1182 events collected by 307

Thickening history of the Western Alps
Earth and Planetary Science Letters, 1986A model of evolution for the western segment of the Alpine chain is presented. Available data concerning the structural, metamorphic and geochronological evolution in the majorunits involved in the thickening processes are takeninto account IO constrain the model.

New occurrence of deerite in the Western Alps
1978Deerite has been found in the Cu-Fe sulfide deposit of Viafiorcia, Western Alps, associated with the Piemonte ophiolite nappe. This hydrous, ferrous, ferric silicate occurs together with Na-amphibole, stilpnomelane+/- white mica, albite and carbonate, and with pyrite, chalcopyrite, bornite, pyrrothite, magnetite +/- sphalerite, mackinawite, linneite ...

Episodic exhumation in the Western Alps
Geology, 2003Oligocene to Miocene clastic sediments of the Tertiary Piedmont Basin (northwest Italy) were derived from erosion of Western Alps source rocks. Detrital white micas from dif- ferent stratigraphic units and from sands of three present-day rivers draining the internal Western Alps have been analyzed by 40 Ar/ 39 Ar geochronology. Our data suggest a wide-

Collision tectonics in the Western Alps
Geological Society, London, Special Publications, 1986Summary This paper gives a brief review of some different models that have been proposed to account for the tectonic development of the Western Alps, emphasizing the field evidence which indicates the major role played by strike-slip tectonics. Sketch maps of the tectonic evolution since Cretaceous times are presented which interpret the Alps

Interplay between erosion and tectonics in the Western Alps
Terra Nova, 2006AbstractBedrock fission‐track analysis, high‐resolution petrography and heavy mineral analyses of sediments are used to investigate the relationships between erosion and tectonics in the Western Alps. Along the Aosta Valley cross‐section, exhumation rates based on fission‐track data are higher in the fault‐bounded western block than in the eastern ...

The use of copper was first established in the western Alps during the late fifth/ early fourth millennia BC. There were several metal-using groups in what is now modern Switzerland during the fourth millennium, including the Cortaillod and Pfyn cultures, followed in the third millennium BC by groups of the Saône-Rhône culture (Strahm 1994).

The architecture of the fault network and the late- to post-metamorphic structural evolution in the internal Cottian Alps have been studied by an integrated approach combining morphostructural analysis, field mapping and detailed mesostructural analysis between the Susa and Pellice Valleys. Available apatite fission track data indicate that this sector
