While the Andes contain many volcanoes, the range itself is a result of subduction. However, the Vosges consist primarily of granite and sandstone and lack any volcanic origin. They are part of the “Hercynian” system of mountains in Europe. During the formation of the Rhine Valley rift, the crust was pushed up, creating the Vosges on one side and the Black Forest on the other. Therefore, unlike the other options, the Vosges do not possess the cone structure, magma vents or eruptive history associated with volcanic mountains.
