Final Report Abstract

Altersdatierungen an verschiedensten Mineralen zur Rekonstruktion von Abkühl- und Exhumationsprozessen in diversen geologischen Settings. Im Besonderen, Datierung von Mineralfeinfraktionen (Illiten) aus Sedimentgesteinen und Störungsletten zur zeitlichen Einstufung von bruchhaften Verformungs- und Hebungsprozessen (Alleinstellungsmerkmal).
