Monkstone Point

Pembrokeshire, SW Wales

Monkstone Point exposes deformed Carboniferous units in three naturally occurring cliff sections. The deformation here is complex: multiple deformation mechanisms can be observed in the cliff sections, including chevron folding, buckle folding, thrusting and thickening of units. Carboniferous siltstones, shales and coal horizons here appear to each have their own characteristic structural style. This suggests that the mechanical properties of these sedimentary units is important for defining how units deform.
