    Notes: Abstract Nine carbonate megaturbidites occur within the succession of siliciclastic turbidite systems of the Eocene Hecho Group. The megaturbidites form exceptionally thick units of virtually basin-wide extent, thus forming excellent marker beds. Each megaturbidite consists of a graded bed which displays a basal megabreccia containing huge slabs of shallow-marine limestones and out-size slope marlstone rip-up clasts. The megaturbidite flows were derived from adjacent carbonate shelves and were probably triggered by major earthquakes associated with thrust propagation. The term of megaturbidite, as descriptively used in this paper. denotes the deposit of an exceptionally large-volume sediment gravity flow.

    Notes: Abstract The Eocene Hecho Group submarine-fan and basin-plain turbidites fill an elongate basin in the south-central Pyrenees that was tectonically active during deposition. The total volume of these sediments is about 21,000 to 26,000 km3. The bulk of the sand by-passed the fan-channel zone and was deposited in the lobe and fan-fringe environments. The stratigraphically lower part of the Hecho submarine fan was deposited during relative lowering of sea level.

    Notes: Abstract Comparison of modern submarine fans and ancient turbidite sequences is still in its infancy, mainly because of the incompatibility of study approaches. Research on modern fan systems mainly deals with morphologic aspects and surficial sediments, while observations on ancient turbidite formations are mostly directed to vertical sequences. The lack of a common data set also results from different scales of observation. To review the current status of modern and ancient turbidite research, an international group of specialists formed COMFAN (Committee on Fans) and met in September 1982 at the Gulf Research and Development Company research facilities in Pennsylvania.

    Notes: Abstract The Cengio sandstone member of the Tertiary Piedmont Basin in northwestern Italy has a conservatively estimated volume of 2.5 to 3 km3 (length: 6.4 km; width: 4.8 km; thickness: 170 m). It is interpreted as a sandstone-rich submarine fan deposit. The Cengio member consists of eight tabular depositional sandstone lobes that are 5- to 25-m thick. These lobes filled a submarine structural depression and onlap and/or pinch-out against bounding slope mudstones. The stacking of the lobe units was related to synsedimentary tectonism.
