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.

来自Spessart和Odenwald地下室（中德晶体区，Variscides）的沉积沉积岩的新碎屑锆石年龄数据揭示了结果，这与当前的构造模型不兼容。先前提出的构造窗口的存在与Spessart和Odenwald地下室的上板块（Saxothuringian带）内的下板块Rhenohercynian岩石不符。这导致了Rheic缝合的新进程，因此导致了这些复合物中两个主要断层带的不连贯性。南部的Spessart Crystalline建筑群可容纳Rheic缝合线，这很可能是由于中德结晶带整个区域向南位移所致。这种位移可能会延伸到Ruhla晶体复合体上。在伯尔斯坦纳·奥登瓦尔德（BöllsteinerOdenwald）的一个单元中，迄今为止发现了一个未知的年龄谱，这可能表明在瓦里斯坎碰撞带中有一小块身份不明的物质。据报道，萨克斯图林根带火成岩侵入的岩浆年龄未知，为350 Ma，可作为区分月桂相关岩和冈瓦纳相关岩的附加指标。
