Origin of arc of the Western Alps
Exploration Geophysics, 1979The arc of the Western Alps started to develop during the main Alpine orogenic phase in Late Eocene to Early Oligocene time. This occurred as a side effect of the general north-south compression in the Central and Eastern Alps. Before this time no arc existed.

Origin of the Alps and Western Mediterranean
Nature, 1971The origin of the Alpine geosyncline may have been related to the eastward motion of Africa relative to Europe during the Mesozoic, and orogenesis in western Europe could have been caused by a westward and then a northward movement of Africa.

Tectonic model for the evolution of the western Alps
Geology, 1993Both European and Adriatic continental margins of the Alpine Piemont ocean were deformed and metamorphosed in the eclogite facies at ∼100 Ma, prior to the main stage of continental collision in the Eocene. We propose that the precollision (Eoalpine) high-pressure metamorphism in the internal crystalline nappes of the western Alps (Dora Maira, Gran ...

Nappe geometry in the Western Swiss Alps
Journal of Structural Geology, 1993Abstract Detailed geological mapping during the last 20 years in the Western Swiss Alps has shown clearly that most of the lower basement nappes are fold nappes possessing normal and inverted limbs. Moreover their cores are made of strongly deformed gneisses indicating that important ductile strain took place during the formation of the fold nappes ...

Ground-Motion Scaling in the Western Alps
Journal of Seismology, 2006In order to empirically obtain the scaling relationships for the high-frequency ground motion in the Western Alps (NW Italy), regressions are carried out on more than 7500 seismograms from 957 regional earthquakes. The waveforms were selected from the database of 6 three-component stations of the RSNI (Regional Seismic network of Northwestern Italy ...

Subduction of continental crust in the Western Alps
Tectonophysics, 1997As a result of recent deep reflection and refraction seismology the crustal structure of the Western Alps is now quite well-defined. However, this raises the question of what is present below the Moho, such as a crustal eclogitic root. This study attempts to estimate the volume of this eclogitic root on the basis of palinspastic reconstructions.

Southwestward thrusting and tectonics of the western Alps
Geological Society, London, Special Publications, 1989Summary The gross geometry of the western Alps is the result of three processes operating since Eocene times: thrusting to WNW; thrusting to SW; arcuate lithospheric flexure due to loading. In the external zones , taken to include the SubBriançonnais domain, these processes are more substantial than ...

Uranium and radon in the Italian Western Alps
2009Italian uranium mineralizations in the western Alps crop out between Maira Valley and the village of Pietra Ligure on the coast. Since the 1950’s, various research has been performed around Besimauda Mount, near the village of Peveragno close the city of Cuneo Piedmont. This brought jobs and better living conditions to the area, since miners could earn

The Great Passes of the Western and Central Alps
The Geographical Journal, 1917Sir Ernest Shackleton, however, had persuaded the Chilian Government to give him once more the use of the Yelcho, and on August 30 he reached Elephant Island on the morrow of a great gale which had driven off the pack and allowed the ship to touch the land and take off the whole, party.
