Base Detfurth Formation

The rocks of the Detfurth Formation (Mittlerer Buntsandstein) were influenced by erosion events during the more recent hardegs and solling cycles of the Buntsandstein and later during the upper upper junction to the lower chalk and therefore lack in the southern and western investigation area. The low altitude generally increases from northwest to southeast. High altitudes are mainly above the salt cushions Lilli/Leila and Hulda as well as along the Diapir flanks of the salt wall Lollo/Lisa.Detfurth组（Detfurth Formation）隶属于中斑砂岩统（Mittlerer Buntsandstein），其岩石曾受斑砂岩统晚期Hardeg旋回（Hardeg Cycle）与Solling旋回（Solling Cycle）期间的侵蚀作用影响，且在后续地层上叠至下白垩统的阶段亦遭受侵蚀，因此该组岩石在研究区的南部与西部均有缺失。研究区整体海拔呈自西北向东南逐渐升高的态势，高海拔区域主要分布于Lilli/Leila与Hulda盐丘（salt cushion）上方，以及Lollo/Lisa盐墙（salt wall）的底辟（diapir）侧翼地带。
