The stratigraphic and structural setting of metamorphic continental units from Alpine Corsica: clues from the area between Asco and Golo valleys (Central Corsica, France)

Journal of Maps, 2020
The area between the Asco and Golo valleys in Central Corsica, France (latitudes 42°47′95″N to 42°37′96″N, longitudes from 9°11′82″E to 9°20′72″E) is a key-sector to investigate the stratigraphic and tectonic setting of Alpine Corsica.

Temperatures and Cooling Rates Recorded by the New Caledonia Ophiolite: Implications for Cooling Mechanisms in Young Forearc Sequences

Geochemistry, Geophysics, Geosystems, 2022
To unveil how forearc lithosphere cools and re‐equilibrates, we carried out a comprehensive geothermometric investigation of the New Caledonia ophiolite, which represents a rare example of proto‐arc section generated during subduction infancy.
