Which mountain in the Alps between Switzerland and Italy was created by marine sedimentary rocks folding into mountain peaks?
Matterhorn The Matterhorn (German: Matterhorn , ] ; Italian: Cervino , ] ; French: Le Cervin , ] ) is a mountain of the Alps, straddling the main watershed and border between Switzerland and Italy. It is a large, near-symmetrical pyramidal peak in the extended Monte Rosa area of the Pennine Alps, whose summit is 4478 m high, making it one of the highest summits in the Alps and Europe. The four steep faces, rising above the surrounding glaciers, face the four compass points and are split by the "Hörnli", "Furggen", "Leone", and "Zmutt" ridges. The mountain overlooks the Swiss town of Zermatt, in the canton of Valais, to the north-east and the Italian town of Breuil-Cervinia in the Aosta Valley to the south. Just east of the Matterhorn is Theodul Pass, the main passage between the two valleys on its north and south sides, and a trade route since the Roman Era.
Mauritanide Belt The Mauritanide Belt is an ancient orogen running parallel to the west coast of Africa from Morocco to Guinea-Bissau. The orogeny that formed the Mauritanide Belt was active between 320 and 270 million years ago in the Carboniferous and Permian. During this time period the eastern nappes of the belt thrusted over rocks of Devonian age in the Taoudeni Basin. During the Triassic the Mauritanide Belt was split from the Appalachian Mountains (with which it was previously a single orogen) as the Atlantic Ocean opened.
