Location
In central Europe the Saxothuringian Zone is situated between the Rhenohercynian Zone to the northwest and the Moldanubian Zone to the southeast. The Hercynian metamorphism of the former zone is generally lower grade; that of the latter zone higher grade than that of the Saxothuringian Zone. West of the Vosges the zone is displaced to the north by a major strike-slip fault, the Bray Fault.
The Saxothuringian Zone is in some places transsected by Permo-Triassic grabens and intramontane basins filled with Rotliegend sediments and older deposits. The Eger Graben in the northwest of Czechia and the Saar-Nahe Basin in western Germany are examples of such structures.
