The Benton Fault is a geological fault in southern Pembrokeshire in Wales that was active as a normal fault during the deposition of the Old Red Sandstone during the Devonian period, forming a thick half graben. [1] During the Carboniferous, the Benton Fault was strongly inverted as part of the Variscan Orogeny. [2]
