This study describes the inversion of a rift-related graben shoulder during emplacement and transport of a major thrust sheet in the external part of the western Northern Calcareous Alps (NCA). Structural fieldwork was carried out along the Lechtal thrust, separating the tectonically deeper Allgäu thrust sheet from the Lechtal thrust sheet. An irregularly shaped Early Jurassic normal fault and an adjacent basin are present in the immediate footwall of the Lechtal thrust. The Early Jurassic age of the basin formation is indirectly established by thickness differences in the syntectonic deposits. Scaly fabric and small-scale drag folds document top S to top SW kinematics at the normal fault. During Alpine orogeny the Lechtal thrust is forced to recess around the graben shoulder in the footwall. A transpressive, dextral tear-fault develops in the hanging wall to compensate for lateral differences of shortening. The normal fault is too steep for inversion, and a shortcut thrust across the half-graben shoulder developed at a shallower angle. It transports the detached half-graben shoulder into the neighbouring basin. Albian to Paleogene transport of the Lechtal thrust sheet caused deformation below the Lechtal thrust, creating a shear zone with isoclinal folds, break thrusts, boudinaged beds and development of S–C fabric. Kinematic analyses of S–C fabrics and small-scale fold axes along the Lechtal thrust show consistent top NW to top N shortening directions in accordance with Cretaceous to Paleogene thrust directions in the NCA.

尿布堆放过程中，分离的半筋肩周围变形（奥地利北部钙质阿尔卑斯山）

这项研究描述了在北部北部钙质阿尔卑斯山（NCA）外部放置和运输主要逆冲片时，裂谷相关的grab肩发生倒转。沿Lechtal推力进行了结构野外工作，将构造上较深的Allgäu推力板与Lechtal推力板分开。莱克塔尔逆冲断层的直接下盘壁上存在一个不规则形状的早侏罗世正断层和一个相邻的盆地。盆地构造的侏罗纪早期时期是由构造构造沉积的厚度差异间接建立的。在正常断层时，鳞片状织物和小范围阻力将文档顶部S折叠到顶部SW运动学。在高山造山过程中，Lechtal推力被迫绕下盘中被grab住的肩部凹陷。具有压抑性 右上角撕裂在悬壁形成，以补偿缩短的横向差异。正常断层太陡而不能反转，并且在半斜肩上形成了较浅的推力。它将分离的半筋肩输送到附近的盆地。阿尔伯特向古近纪的Lechtal冲断层的运输导致了Lechtal冲断以下的变形，形成了一个剪切带，该剪切带具有等斜褶皱，断裂冲断，粘结床和SC织物的发育。沿Lechtal推力的S–C织物和小规模折叠轴的运动学分析表明，与NCA中的白垩纪至古近纪推力方向一致，顶部NW到顶部N缩短方向一致。并以较浅的角度在半结实的肩膀上产生了短推力。它将分离的半筋肩输送到附近的盆地。阿尔伯特向古近纪的Lechtal冲断层的运输导致了Lechtal冲断以下的变形，形成了一个剪切带，该剪切带具有等斜褶皱，断裂冲断，粘结床和SC织物的发育。沿Lechtal推力的S–C织物和小规模折叠轴的运动学分析表明，与NCA中的白垩纪至古近纪推力方向一致，顶部NW到顶部N缩短方向一致。并以较浅的角度在半结实的肩膀上产生了短推力。它将分离的半筋肩输送到附近的盆地。阿尔伯特向古近纪的Lechtal冲断层的运输导致了Lechtal冲断以下的变形，形成了一个剪切带，该剪切带具有等斜褶皱，断裂冲断，粘结床和SC织物的发育。沿Lechtal推力的S–C织物和小规模折叠轴的运动学分析表明，与NCA中的白垩纪至古近纪推力方向一致，顶部NW到顶部N缩短方向一致。产生一个具有等斜褶皱，断裂推力，束缚床和S–C织物发育的剪切带。沿Lechtal推力的S–C织物和小规模折叠轴的运动学分析表明，与NCA中的白垩纪至古近纪推力方向一致，顶部NW到顶部N缩短方向一致。产生一个具有等斜褶皱，断裂推力，束缚床和S–C织物发育的剪切带。沿Lechtal推力的S–C织物和小规模折叠轴的运动学分析表明，与NCA中的白垩纪至古近纪推力方向一致，顶部NW到顶部N缩短方向一致。
