阿尔卑斯赫尔维特推覆休的几何特征表明,强烈的内部变形主要是在推覆体运移过程中由简单剪切引起的。推覆体以软弱层为界,并且在构這运移方向上切过强硬层向上举移,地层的层理与推覆体界面斜交。冲断面继发育在下伏的前三叠纪的片麻岩基底中的韧性剪切帶而形成。随着变形增大,较宽的剪切带向下变窄形成强烈剪切带,并最终成为冲断层。顺着与剪切面针交的强层的压缩产生了纵弯褶坡。这些褶皱的几何形态由于受进一步的剪切而被改造,如当它们的正常翼位在简单剪切应变椭圆的伸张区内时导致了正断层。
Geometrical characteristics of the Helvetia hike off-season in the Alps show that strong internal deformation is mainly caused by simple shearing during nappe transport. The nappe body is bounded by a weak layer, and the strong layer is moved upwards in the direction of the migration. The stratification of the strata intersects with the nappe interface. The thrust surface is formed following the ductile shear zone developed in the underlying Pre-Triassic gneiss basement. As the deformation increases, the wider shear band narrows downwards to form a strong shear zone and eventually becomes a thrust fault. Longitudinal folds were created along the compression of the strong layers of the cut pins. These fold geometries are modified due to further shearing as they lead to normal faults when their normal wing positions are within the simple shear strain oval stretch.
