A view of the axis of the right-hand syncline shown in the previous photo at beach level. The Bude Formation here consists of alternating thin beds of turbidite sandstones (pale grey/brown) and fine-grained shaly siltstones/mudstones (darker grey). These chevron folds are 'similar' in style, rather than concentric. This means that material (mostly the weaker shaly beds) has had to 'flow' into the hinge zones - notice how it is thicker in the hinge, compared with the limbs of the fold.
