Extentional faults: Saundersfoot south

Saundersfoot to Swallowtree Bay geological structures

Just south of Saundersfoot harbour, immediately adjacent to the previous photo, a set of extensional ('normal') faults with a small displacements cut Lower Coal Measures rocks: mostly mudstones with ironstone bands and nodules, with thin sandstone bands and laminae in the upper part.

The small thrust with a footwall syncline in the previous photo is just visible at the lower right.

The walking stick is 0.9 m long.
