We present insights into the Cenozoic tectonic evolution of the region around the Pontarlier strike‐slip fault zone within the Jura fold‐and‐thrust belt by combined study of paleostress and geomorphic analyses. A preliminary separation of heterogeneous fault‐slip data and bedding‐tilt correction was performed before determining the paleostress axes orientations. The paleostress results provide evidence of multiphase deformation history consisting of four successive events. These events include a strike‐slip stress regime with ∼N‐S directed compression, a NW‐SE directed extensional stress regime, a NW‐SE trending compressional stress regime, and a strike‐slip stress regime with a mean NW‐SE directed compression. The directions of extension and compression for the second and third events are consistent with the general direction of maximum horizontal far‐field stress near the northern segment of the Pontarlier fault and generally deviate from those found near the southern segment.

蓬塔里尔走滑断裂带（瑞士和法国侏罗褶皱冲断带）的新生代构造变形：古应力和地貌分析的见解

通过对古应力和地貌分析的综合研究，我们对侏罗纪褶皱冲断带蓬塔利耶走滑断裂带周围地区的新生代构造演化提出了见解。在确定古应力轴方向之前，先对异质断层滑动数据和层理倾斜校正进行了初步分离。古应力结果提供了由四个连续事件组成的多相变形历史的证据。这些事件包括具有‐N‐S定向压缩的走滑应力状态，具有NW‐SE的拉伸应力状态，NW‐SE趋向的压缩应力状态以及具有平均NW‐SE的压缩趋势的走滑应力状态。
