Glueckstadt地堑是中欧盆地体系中最深的二叠纪后构造之一，位于从北海到波罗的海以及从下萨克森州盆地到Rynkoebing-Fyn高地的“心脏”位置。利用选定的地震线、地震平坦和三维构造模型研究了中生代至近代的演化。中晚三叠世晚期（Keuper）的一个主要构造事件是伴随着Glueckstadt地堑内的强盐构造。当时，在中部发生了快速的下沉，形成了Glueckstadt地堑的“核心”。该区后三叠纪构造演化不遵循典型的热沉降模式。相比之下，似乎有一个缓慢的渐进式的盐运动激活是由最初的三叠纪事件触发的。从侏罗纪开始，沉降中心分为两个部分，位于三叠纪“核心”附近。与中欧盆地系统的其他地区相比，Glueckstadt地堑没有受到侏罗纪和白垩纪额外事件的强烈影响。晚侏罗世至早白垩世，Glueckstadt地堑周围地区受相对隆升和隆起地形的区域性侵蚀作用的影响。然而，在新生代，北海形成了一个强烈的沉降中心，重新激活并加速了沉降。古近纪和第四纪—新近纪期间，两个沉积中心逐渐向盆地侧翼移动。这些数据确实表明，三叠纪沉降中心的初始枯竭引发了盐的逐渐退出，从而控制了二叠纪后的演化。从这个意义上说，Glueckstadt地堑至少部分形成于后二叠纪时期的“盆地规模边缘向斜”。今天的汉堡槽、东槽和威斯特尔施泰因槽是这一长期过程的实际最终状态，这一过程仍可能继续，并可能在年轻的过程中发挥作用，例如，用于海岸保护。
The Glueckstadt Graben is one of the deepest post-Permian structures within the Central European Basin system and is located right at its “heart” at the transition from the North Sea to the Baltic Sea and from the Lower Saxony Basin to the Rynkoebing–Fyn High. The Mesozoic to recent evolution is investigated by use of selected seismic lines, seismic flattening and a 3D structural model. A major tectonic event in the latest Middle–Late Triassic (Keuper) was accompanied by strong salt tectonics within the Glueckstadt Graben. At that time, a rapid subsidence took place within the central part, which provides the “core” of the Glueckstadt Graben. The post-Triassic tectonic evolution of the area does not follow the typical scheme of thermal subsidence. In contrast, it seems that there is a slow progressive activation of salt movements triggered by the initial Triassic event. Starting with the Jurassic, the subsidence centre partitioned into two parts located adjacent to the Triassic “core.” In comparison with other areas of the Central European Basin system, the Glueckstadt Graben was not strongly affected by additional Jurassic and Cretaceous events. During the late Jurassic to Early Cretaceous, the area around the Glueckstadt Graben was affected by relative uplift with regional erosion of the elevated relief. However, subsidence was reactivated and accelerated during the Cenozoic when a strong subsidence centre developed in the North Sea. During Paleogene and Quaternary–Neogene, the two centres of sedimentation moved gradually towards the flanks of the basin. The data indeed point toward a control of post-Permian evolution by gradual withdrawal of salt triggered by the initial exhaustion along the Triassic subsidence centre. In this sense, the Glueckstadt Graben was formed at least partially as “basin scale rim syncline” during post-Permian times. The present day Hamburger, East and Westholstein Troughs are the actual final state of this long-term process which still may continue and may play a role in terms of young processes and, e.g., for coastal protection.
