Turbidites around an active fault scarp on the Lower Valencia Fan, northwest Mediterranean

Side-scan sonar images from the Lower Valencia Fan show that turbidite bedforms (chevrons) and net sediment aggradation vary around a small fault scarp. One or more turbidity currents were affected by the fault, but the exact timing of the fault movement in relation to the chevrons is not known. A scaled laboratory experiment showed that mean flow vector would not be affected by a current flowing over an obstacle of similar height to flow depth ratio.
