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.
