La Chartreuse
Near Le Touvet, north of Grenoble, France. The Chartreuse massif is composed of layers of marl (calcareous mudstone) and limestone that were laid down under the Tethys Ocean during the Cretaceous period (about 145-65 million years ago). These rocks were subsequently compressed, folded and uplifted during the Alpine Orogeny, or mountain-building event (from 65 million years ago and still ongoing). The Alpine Orogeny was caused by the collision of the Eurasian and the African plates.
