− | Similarly, where the axis of a fault-bend fold on a hanging wall is fixed relative to the bend of the fault on the foot wall, the actual rock occupying the fold changes during movement along the fault. However, the position of the trap remains approximately fixed relative to the footwall and the fault bend. | + | Similarly, where the axis of a fault-bend [[fold]] on a hanging wall is fixed relative to the bend of the fault on the foot wall, the actual rock occupying the fold changes during movement along the fault.
