The Maira-Sampeyre and Val Grana Allochthons (south Western Alps): review and new data on the tectonometamorphic evolution of the Briançonnais distal margin
Here we describe the structure, the high-pressure, low-temperature (HP-LT) metamorphism
and tectonic evolution of the Briançonnais distal margin units from the south Western Alps …

Protracted Subduction of the European Hyperextended Margin Revealed by Rutile U‐Pb Geochronology Across the Dora‐Maira Massif (Western Alps)
G Bonnet, C Chopin, M Locatelli… - …, 2022 - Wiley Online Library
Abstract The Dora‐Maira massif is an archetypal nappe stack of subducted and exhumed
upper crust. Slices of continental crust experienced metamorphism at upper blueschist to …

Pre‐Alpine (Variscan) inheritance: a key for the location of the future Valaisan Basin (Western Alps)
The boundary between the Helvetic and the Penninic (= Briançonnais) Zones has long been
recognized as a major fault (“Penninic Front”) in the Western Alps. A narrow oceanic domain …

[HTML][HTML] The cold and hot collisional orogens: Thermal regimes and metallogeny of the Alpine versus Himalayan-Tibetan belts
It is commonly believed that the thermal regime of collisional orogens evolves from cold to
hot with time. Here, we compare the Alpine and Himalayan-Tibetan orogens in terms of their …

A window into an older orogenic cycle: P–T conditions and timing of the pre‐Alpine history of the Dora‐Maira Massif (Western Alps)
F Nosenzo, P Manzotti, M Poujol… - Journal of …, 2022 - Wiley Online Library
Deciphering the pre‐orogenic evolution of subducted continental basement is challenging
due to pervasive reworking of crust during subduction and exhumation. Survival of such …

[PDF][PDF] What's in the sandwich? New P–T constraints for the (U) HP nappe stack of southern Dora-Maira Massif (Western Alps)
The Brossasco-Isasca Unit (BIU) of the southern Dora-Maira Massif (DMM), Western Alps, is
one of the most studied ultra-high pressure (UHP) units in the world. However, the …

Exhumation rates in the Gran Paradiso Massif (Western Alps) constrained by in situ U–Th–Pb dating of accessory phases (monazite, allanite and xenotime)
Exhumation rates for high-pressure metamorphic rocks need to be carefully estimated to
decipher tectonic processes in subduction/collision belts. In the Gran Paradiso Massif …

[HTML][HTML] H2O budget and metamorphic re-equilibration in polycyclic rocks as recorded by garnet textures and chemistry
F Nosenzo, P Manzotti, M Robyr - Lithos, 2023 - Elsevier
Massive dehydration is expected to occur during oceanic subduction. The situation is quite
different during continental subduction, where often a large amount of crustal material has …
