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.

Inversion Structures
Lurestan Region, Zagros
​
​
Roadside exposure of deep water Early Jurassic radiolarites in the Lurestan region of the Zagros Fold Belt. The exposure is characterized by abundant extensional faults, many of which record syn-depositional offset. Neogene shortening has caused the development of kink folds, buttress structures, and partial reactivation of extensional faults.
