Cwm Llwyd Fault

Cwm Llwyd Fault

The Cwm Llwyd Fault is a fault in the Black Mountains of South Wales. It moved as a sinistral (left lateral) strike-slip fault during the Variscan Orogeny. Together with the Llwyn Celyn Fault it formed a left-stepping offset that created a pull apart structure, which preserved the Cwm Llwyd Outlier of Namurian rocks.[1]
