Asymmetric anticline, Swallowtree Bay north

Saundersfoot to Swallowtree Bay geological structures

An asymmetric anticline chevron fold developed in Lower Coal Measures sandstones just north of Swallowtree Bay near Saundersfoot. The fold has a vertical to slightly overturned northern limb. In the centre of the photo, minor thrusts disrupt the fold axis slightly, to accommodate the 'space problem'.
