Highlight on the thrust (folded) bringing Zermatt-Saas unit (metaoceanic, amphibolites with eclogitic relics, ex basaltic tholeiitic affinity) over Monte Rosa nappe (variscan metacontinental litosphere, Brianzonese – Pennidic domain, paragneiss with granatiferous micaschists). By the contact you can see metasomatic effects with amphibole rocks (“actinolite-tremolite series” – “tremolititi” auct.), talc and chlorites. From east sector of Corno…
Highlight on the thrust (folded) bringing Zermatt-Saas unit (metaoceanic, amphibolites with eclogitic relics, ex basaltic tholeiitic affinity) over Monte Rosa nappe (variscan metacontinental litosphere, Brianzonese – Pennidic domain, paragneiss with granatiferous micaschists). By the contact you can see metasomatic effects with amphibole rocks (“actinolite-tremolite series” – “tremolititi” auct.), talc and chlorites. From east sector of Corno Camoscio (Stolemberg area), next to (ex) “Città di Vigevano” refugee, under Passo dei Salati (Salati pass), about 3000m asl, Gressoney valley – Sesia valley watershed, Pennine Alps, northwestern Alps.
