Swallowtree Bay anticline-syncline couplet: detail 3

Saundersfoot to Swallowtree Bay geological structures

Detailed portrait format view no.3 of the asymmetric anticline-syncline couplet in Lower Coal Measures sandstones and siltstones, just south of Swallowtree Bay.

This is a view of the siltstones and sandstones in the fold axis of the anticline. The southern (left) limb of the fold shows much crumpling and shearing in the weaker, laminated siltstones.

I took this photo for the shapes, textures and colours as well as the geological interest, hence I omitted a scale object. The section shown is about 1.8 metres in height.

The photo of the entire structure is here:
