    • Net Tectonic Rotation Analysis

    The net rotation of a dyke (including any component of tilt and vertical axis rotation) is calculated as a single rotation around an inclined axis, which restores the in situ remanence direction to its initial orientation (reference pole) and the dyke to its initial vertical position. This technique allows the user to calculate the rotation parameters of the deformation experienced by the dyke and its initial orientation.
