Abstract
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.
