Folding at Broadhaven
Pembrokeshire, SW Wales
One of The Geological Society's 100 Great Geosites. Asymmetric folds in interbedded Carboniferous siltstones, shales and coal horizons are cut here by a number of northward-propagating thrusts. This classic structure has been studied in some detail (e.g. Williams and Chapman,1983) as it provides an excellent outcrop example to examine the interplay between faulting and folding during deformation.
Trevayne
Pembrokeshire, SW Wales
Large-scale harmonic fold within Carboniferous siltstones, shales and coal horizons. Close inspection of the fold core reveals several low offset thrust segments which probably formed to accommodate the relatively tight interlimb angle here. The cross-section below shows the transition in structural style between this location, Monkstone Point and Saundersfoot.

West Angle Bay
Pembrokeshire, SW Wales
Lower Limestone Series of Carboniferous age, SW Wales. This wave-cut platform exposes complex deformation patterns within these carbonate units: folds and thrusts are laterally discontinuous, with anticlines, and synclines transitioning into thrust segments along strike.
