Syncline in Middle Cove islet, Stackpole Quay, Pembrokeshire.

This is a view of the plunging syncline in the small islet in Middle Cove, just north of Stackpole Quay, Pembrokeshire. The fold is developed in Carboniferous Limestone, with a plunging axis trending approximately ESE-WNW, dipping easterly.

The fold style is mostly concentric, but the 'space problem' in the centre of the fold has been accommodated by small-scale thrusting and crumpling, and additional movement taking place along bedding planes.
