Small thrust and footwall syncline

Saundersfoot to Swallowtree Bay geological structures

Just south of Saundersfoot Harbour is a small thrust with a footwall syncline in Lower Coal Measures rocks. The anticline component of the fold couplet has been sheared out by the thrust.

The rocks are mainly grey mudstones with brown ironstone bands and nodules, with thin pale grey sandy lamine in the upper part and to the bottom right.

The walking stick is 0.9 m long.
