Swallowtree Bay anticline-syncline couplet: detail 9
Saundersfoot to Swallowtree Bay geological structures
Detail view no.9 of the asymmetric anticline-syncline couplet in Lower Coal Measures sandstones and siltstones, just south of Swallowtree Bay.
This photo shows the asymmetric syncline of the fold couplet pair. On the left, the fold limb is vertical, becoming overturned towards the top of the photo. The opposite limb dips gently to the south (right). The sandstone beds show channelling and thickness variations, especially just above the top of the walking stick. The sandstones also dispaly a strong fracture fan cleavage perpendicular to the bedding, in contrast to the darker, weaker, darker siltstones which show little or no cleavage.
The walking stick is 0.9 m long.
The photo of the entire structure is here:
