The structure of the Upper Triassic (Keuper) sequence based on the deep borehole data and interpretation of seismic lines within Glueckstadt Graben

A detailed study of the structure and evolution of the Glueckstadt Graben (GG) shows<br>that the main phase of subsidence occurred during Late Triassic (Keuper) times. This<br>subsidence was strongly affected by Permian (Zechstein and Rotliegend) salt movement with<br>formation of very complicated structures of Upper Triassic sedimentary succession.<br>Furthermore, the deepest part of the GG partially formed as “rim syncline” at least within<br>southern part in Late Triassic. It is possible, that the Triassic GG an inherited structure from<br>Late Paleozoic (Early Permian).
