View from Durdle Door looking east across Man O�War Bay towards Dungy Head on the south Dorset Coast. The spectacular cliff and offshore reef exposures contain sub-vertical to locally overturned Upper Jurassic�Upper Cretaceous sediments of the steep, north limb of the Purbeck monocline, a fold developed through positive structural inversion in the Wessex Basin. The structural geometries displayed are consistent with those that typify Late Cretaceous and Cenozoic basin inversion in the Southern North Sea, the effects of which directly influence fault reactivation and seal integrity of CH4 and CO2 gas entrapment there, the subject of the paper by Underhill et al. in this issue (pp. 291�304).
