Alps highest peak meets folded sea floor

by Antoine Clausse, CNRS / Université de Strasbourg, Strasbourg, France

At the late Jurassic, this dolostsone was the former sea floor but after millions years of tectonic movements and natural forces, these rocks chair at 3000m. The Mont Blanc, highest peak of the Alps is less than 20km away in the background. Thank to the Alpine collision, former sea floor is thrusted over gneiss and granite to make the happiness of geologists and mountaineers.
