... such as the southward-vergent Carmel Head Thrust formed. Extensional reactivation of the Acadian structures in early Mississippian time defined the northern edge of the offshore Bowland Basin. The relatively late brittle structures of the Menai Strait fault system locally exhume the Penmynydd Zone and define...

and the Central shales, both of which are of Lower Silurian age. In this model, southward compression during the Upper Paleozoic produced the Carmel Head thrust, and to the south of this, a large-scale syncline with the northern limb overturned toward the south. The Penymynydd fault is considered to be an oblique

... of the northward-dipping Carmel Head Thrust system (Greenly 1919). The Porth-y-pistyll area lies in the hanging wall, some 2.5 km above the main thrust in this system, the Carmel Head Thrust sensu stricto, but is cut by smaller northward dipping faults interpreted as splays from the sole thrust. The Carmel Head...
