Im Zuge dieses Vorgangs entstanden im Erdmantel Basaltschmelzen, die an die Untergrenze der Kruste emporstiegen, die Kruste aufheizten und diese teilweise sogar aufschmolzen. Dabei entstanden Granite und Pegmatite, die im Sü dalpin und Ostalpin hä ufi g anzutreffen sind. An der Erdoberfl ä che kam es weit verbreitet zu einem explosiven, quarzreichen Vulkanismus. Bekanntestes Beispiel ist der so genannte Bozener Quarzporphyr, der in Sü dtirol als hunderte Meter dicke Fü llung eines riesigen vulkanischen Einbruchskraters erhalten ist.< / p > < / div > < / div > < / div >

Das Relief wurde im Laufe des Perm von wenigen hundert Metern Seehö he teilweise bis auf Meeresniveau abgesenkt. Im jü ngeren Perm wurden das heutige Sü dalpin und Teile des Ostalpins von Sü dosten her von der Tethys wiederholt ü berfl utet. Diese Meeresvorstö ß e hinterließ en im Sü dalpin fossilreiche Flachwasserkalke mit Fusuliniden. Im Ostalpin trockneten die Buchten immer wieder vö llig aus und hinterließ en Salz- und Gipsablagerungen, die etwa im Salzkammergut zu sehen sind.< / p > < / div > < / div > < / div >
