The correct identification of upper flow-regime sedimentary structures in the cool-water carbonate realm is crucial to the development of realistic depositional models that predict the distribution of thick and widespread carbonate sandstones and conglomerates. This disser-tation presents a case study of the cool-water carbonate ramp succession in the Lower Pleistocene of Favignana Island, Sicily. Excellent exposures enable the detailed analysis of sedimentary structures and the reconstruction of upper flow-regime bedform morpho-dynamics, herewith elucidating the sedimentary processes that operate in such depositional environments. It is demonstrated that high-energy, supercritical flows leave a major imprint on the carbonate sediment bodies thus created. The present work contributes to our understanding of the genesis of such bodies by revealing a catastrophic signature in the evolution of cool-water carbonate ramps, which is directly linked to the predictability of the distribution of important reservoir units in the subsurface.
