| Description | In many exposed faults we fail to determine the slip direction and sense due to the absence of clear macroscopic kinematic indicators. To improve this situation we have been working out a technique employing the X-ray imaging of narrow faults by micro-computed tomography to reveal their cryptic strain fabric. It is expected that a detailed knowledge of 3-D particle orientation will allow resolving the shear kinematics. Here, we give a methodical concept and preliminary results of a pilot study to validate this assumption. The approach tested is potentially suitable for coarser clastic sediments or clasts-in-matrix lithologies representing common examples of faulted rocks in which slickensides typically do not develop. |
