In the Dent Blanche Tectonic System, the Mont Morion biotite-bearing granite is a km- scale intrusion preserved in a low-strain volume. Zircon saturation thermometry suggests that it crystallised from a melt that reached about 800 °C. U–Pb zircon and allanite geochronology indicates crystallization of the magma in the Permian (290 ± 3 Ma; 280 ± 8 Ma, respectively). Migmatitic...
- Permian ages have been determined for the
Mont Collon and Cervino gabbros (284 ± 1 Ma, U/Pb on
zircon; Monjoie et al. 2005; 250 ± 5 Ma, K/Ar and Rb/Sr
methods, Dal Piaz et al. 1977), as well as for a greenish
orthogneiss sampled south of the Matterhorn (289 ± 2 Ma,
U/Pb on zircon, Bussy et al. 1998)....
- The DBTS is made of the Dent
Blanche (DB) and the Mont Mary-Cervino (MM) nappes
(Fig. 1) that are separated by the Roisan-Cignana Shear
Zone (RCSZ), an Alpine km-scale high strain zone (Manzotti 2011; Manzotti et al. 2014b)....
