英文摘要	New detrital zircon age data of metasedimentary rocks from the Spessart and Odenwald basement (Mid-German Crystalline Zone, Variscides) revealed results, which are not compatible with current tectonic models. The previously proposed existence of a tectonic window, which includes lower plate Rhenohercynian rocks within the upper plate (Saxothuringian Zone) in the Spessart and Odenwald basement, does not agree with the results of this study. This leads to a new course of the Rheic suture and, therefore, a non-coherence of the two major fault zones in these complexes. The southern Spessart Crystalline Complex accommodates the Rheic suture, which is most likely explained by a southward displacement of a whole segment of the Mid-German Crystalline Zone. This displacement might extend over the Ruhla Crystalline Complex. A hitherto unknown age spectrum of a unit in the Böllsteiner Odenwald was found, which might indicate a sliver of unidentified material in the Variscan collision zone. An unknown magmatic age of 350 Ma is reported for igneous intrusions in the Saxothuringian Zone and can be used as an additional indicator to distinguish between Laurussia- and Gondwana-related rocks. © 2020, Geologische Vereinigung e.V.
