Pembrokeshire, SW Wales
Just south of the classic Den's Door outcrop, the structures here exhibit complex patterns of fold and thrust interaction. Asymmetric, northward-verging folds in interbedded Carboniferous siltstones, shales and coal horizons are cut here byseveral northward-propagating thrusts associated with the Variscan Orogeny.
These structures has been studied in some detail (e.g. Williams and Chapman,1983; Nicol et al., 2002) as it provides an excellent outcrop example to examine the interplay between faulting and folding during deformation.
