Matterhorn - Geology

Geology

Apart from the base of the mountain, the Matterhorn is composed of gneiss belonging to the Dent Blanche klippe, an isolated part of the Austroalpine nappes, lying over the Penninic nappes. The Austroalpine nappes are part of the Apulian plate, a small continent which broke up from Africa before the Alpine orogeny. For this reason the Matterhorn has been popularized as an African mountain. The Austroalpine nappes are mostly common in the Eastern Alps.

The Swiss explorer and geologist Horace-Bénédict de Saussure, inspired by the view of the Matterhorn, anticipated the modern theories of geology:

What power must have been required to shatter and to sweep away the missing parts of this pyramid; for we do not see it surrounded by heaps of fragments; one only sees other peaks - themselves rooted to the ground - whose sides, equally rent, indicate an immense mass of débris, of which we do not see any trace in the neighbourhood. Doubtless this is that débris which, in the form of pebbles, boulders, and sand, fills our valleys and our plains.
