Abstract

Flood-generated turbidity currents represent an important process of marine sedimentation. However, no deposit related to this process has yet been described at sea. Turbiditic sequences cored at 2000 m water depth in the Mediterranean show tractive structures and superposition of reverse and normal grading. They are related to floods triggered during the twentieth century. Deposits from flood-generated turbidity currents have a great impact on the interpretation of deep-ocean paleoclimate records obtained near continental margins by linking deep-marine sedimentary records to continental climatic changes through flood frequency and magnitude. Implications of this study should help redefine the reservoir character of oil fields in fine-grained turbidites.
