 Known as the Variscan orogeny in Central Europe, the mountain building event left remnant highlands throughout Europe, northwestern Africa and North America.The Alps and the Bohemian Massif were affected by the orogeny.The Sub-Penninic and Moldanubian superunits were deeply buried within the new range (granulites in the Moldanubian Superunit, for instance, formed at 55 kilometers depth), while the Austroalpine superunit likely formed foothills.
