An extensive, reprocessed two‐dimensional (2D) seismic data set was utilized together with available well data to study the Tiddlybanken Basin in the southeastern Norwegian Barents Sea, which is revealed to be an excellent example of base salt rift structures, evaporite accumulations and evolution of salt structures. Late Devonian–early Carboniferous NE‐SW regional extensional stress affected the study area and gave rise to three half‐grabens that are separated by a NW‐SE to NNW‐SSE trending horst and an affiliated interference transfer zone. The arcuate nature of the horst is believed to be the effect of pre‐existing Timanian basement grain, whereas the interference zone formed due to the combined effect of a Timanian (basement) lineament and the geometrical arrangement of the opposing master faults. The interference transfer zone acted as a physical barrier, controlling the facies distribution and sedimentary thickness of three‐layered evaporitic sequences (LES). During the late Triassic, the northwestern part of a salt wall was developed due to passive diapirism and its evolution was influenced by halite lithology between the three‐LES. The central and southeastern parts of the salt wall did not progress beyond the pedestal stage due to lack of halite in the deepest evaporitic sequence. During the Triassic–Jurassic transition, far‐field stresses from the Novaya Zemlya fold‐and‐thrust belt reactivated the pre‐salt Carboniferous rift structures. The reactivation led to the development of the Signalhorn Dome, rejuvenated the northwestern part of the salt wall and affected the sedimentation rates in the southeastern broad basin. The salt wall together with the Signalhorn Dome and the Carboniferous pre‐salt structures were again reactivated during post‐Early Cretaceous, in response to regional compressional stresses. During this main tectonic inversion phase, the northwestern and southeastern parts of the salt wall were rejuvenated; however, salt reactivation was minimized towards the interference transfer zone beneath the centre of the salt wall.

挪威巴伦支海东南部Tiddlybanken盆地的蒸发岩堆积和盐结构动力学构造

利用广泛的，经过重新处理的二维（2D）地震数据集和可用的井眼数据，研究了挪威巴伦支海东南部的Tiddlybanken盆地，这被证明是碱盐裂谷结构，蒸发岩成藏和演化的极佳例子。盐结构。泥盆纪晚期-石炭纪NE-SW早期区域性张应力影响了研究区域，并产生了三个半筋，它们被西北偏南地区分隔为北西北偏南地区趋势的趋势和相关的干扰转移区。霍斯特的弓形性质被认为是预先存在的Timanian基底晶粒的影响，而干涉区域则是由于Timanian（基底）线性和相对的主断层的几何排列共同作用而形成的。干扰转移区起到了物理屏障的作用，控制了三层蒸发序列（LES）的相分布和沉积厚度。在三叠纪晚期，盐岩的西北部是由于被动底辟作用而发育的，并且其演化受到了三个LES之间盐岩岩性的影响。盐壁的中部和东南部由于在最深的蒸发序列中缺少盐岩，因此没有超过基座阶段。在三叠纪-侏罗纪过渡期，Novaya Zemlya褶皱-冲断带的远场应力重新激活了盐下石炭纪裂谷结构。活化导致Signalhorn圆顶的发展，使盐墙的西北部重新焕发活力，并影响了东南大盆地的沉积速率。响应区域压缩应力，在早白垩世后，盐壁，Signalhorn圆顶和石炭纪盐前构造再次被激活。在这个主要的构造反转阶段，盐墙的西北部和东南部恢复了活力。但是，在盐壁中心下方的干扰转移区，盐的再活化最小。来自Novaya Zemlya褶皱和冲断带的远场应力重新激活了盐前石炭纪裂谷结构。活化导致Signalhorn圆顶的发展，使盐墙的西北部重新焕发活力，并影响了东南大盆地的沉积速率。响应区域压缩应力，在早白垩世后，盐壁，Signalhorn圆顶和石炭纪盐前构造再次被激活。在这个主要的构造反转阶段，盐墙的西北部和东南部恢复了活力。但是，在盐壁中心下方的干扰转移区，盐的再活化最小。来自Novaya Zemlya褶皱和冲断带的远场应力重新激活了盐前石炭纪裂谷结构。活化导致Signalhorn圆顶的发展，使盐墙的西北部重新焕发活力，并影响了东南大盆地的沉积速率。响应区域压缩应力，在早白垩世后，盐壁，Signalhorn圆顶和石炭纪盐前构造再次被激活。在这个主要的构造反转阶段，盐墙的西北部和东南部恢复了活力。但是，在盐壁中心下方的干扰转移区，盐的再活化最小。使盐墙的西北部重新焕发活力，并影响了东南大盆地的沉积速率。响应区域压缩应力，在早白垩世时期，盐壁，Signalhorn圆顶和石炭纪盐前构造再次被激活。在这个主要的构造反转阶段，盐墙的西北部和东南部恢复了活力。但是，在盐壁中心下方的干扰转移区，盐的再活化最小。使盐墙的西北部重新焕发活力，并影响了东南大盆地的沉积速率。响应区域压缩应力，在早白垩世时期，盐壁，Signalhorn圆顶和石炭纪盐前构造再次被激活。在这个主要的构造反转阶段，盐墙的西北部和东南部恢复了活力。但是，在盐壁中心下方的干扰转移区，盐的再活化最小。在这个主要的构造反转阶段，盐墙的西北部和东南部恢复了活力。但是，在盐壁中心下方的干扰转移区，盐的再活化最小。在这个主要的构造反转阶段，盐墙的西北部和东南部恢复了活力。但是，在盐壁中心下方的干扰转移区，盐的再活化最小。
