In this study, we investigate the regional tectonic impact on salt movement at the northeastern margin of the intracontinental North German Basin. We discuss the evolution of salt pillows in the Bay of Mecklenburg in the light of thick‐ and thin‐skinned tectonics, including gravity gliding, and differential loading using seismic imaging. Stratigraphic and structural interpretation of a 170 km long, multichannel seismic line, extending from the Bay of Mecklenburg to northeast of Rügen Island, incorporates well information of nearby onshore wells. This new high‐resolution seismic line completely images the stratigraphic and tectonic pattern of the subsurface, from the base of the Zechstein to the seafloor. Our analysis reveals that subsidence during Late Triassic to Early Cretaceous at the northeastern basin margin was associated with transtensional dextral strike slip movement within the Trans‐European Suture Zone. We reinterpret the Werre and Prerow Fault Zones west of Rügen Island as an inverted, thin‐skinned normal fault system associated with the formation of the Western Pomeranian Fault System. Salt movement in the Bay of Mecklenburg was initiated in the Late Triassic and lasted until the Early Jurassic. A second phase of salt pillow growth occurred during the Coniacian until Cenozoic and correlates with compression‐related regional basin inversion due to the onset of the Africa‐Iberia‐Europe convergence. Thin‐skinned extensional initialization of salt pillow growth and compressional salt remobilization explains salt pillow evolution in the Bay of Mecklenburg. Additionally, we discuss an impact of gravity gliding on salt pillow evolution induced by basin margin tilt.

北德北部盆地边缘的构造演化：从最初的三叠纪盐运动到晚白垩世-新生代运动

在这项研究中，我们调查了北德陆盆地内陆东北缘对盐运动的区域构造影响。我们根据厚皮和薄皮构造，包括重力滑移和地震成像的差分荷载，讨论了梅克伦堡湾盐枕的演化。从梅克伦堡湾一直延伸到吕根岛东北的一条长170公里的多通道地震线的地层和结构解释结合了附近陆上油井的油井信息。从Zechstein底部到海底，这条新的高分辨率地震线完全反映了地下的地层和构造模式。我们的分析表明，东北盆地边缘的三叠纪晚期至白垩纪晚期的沉降与跨欧洲缝合带内的张性右旋走滑运动有关。我们将吕根岛以西的Werre和Prerow断层带重新解释为与西部Pomeranian断层系统形成有关的反向，薄皮正断层系统。梅克伦堡湾的盐运动始于三叠纪晚期，一直持续到侏罗纪早期。盐枕生长的第二阶段发生在Coniacian直到新生代，并且由于非洲-伊比利亚-欧洲交汇的开始而与受压相关的区域盆地反转有关。盐枕生长的薄皮扩展初始化和压缩盐迁移解释了梅克伦堡湾盐枕的演化。此外，我们讨论了重力滑动对盆地边缘倾斜引起的盐枕演化的影响。
