f Seismic Geomorphology and Depositional Systems of Deep Water Environments; Observations from Offshore Nigeria, Gulf of Mexico, and Indonesia

1009 SEISMIC GEOMORPHOLOGY AND DEPOSITIONAL SYSTEMS OF DEEP WATER ENVIRONMENTS; OBSERVATIONS FROM OFFSHORE NIGERIA GULF OF MEXICO AND INDONESIA 1 Four principal depositional elements are recognized in deep-water depositional environments offshore Nigeria Gulf of Mexico and Indonesia. These include channels levees frontal splays and debris flow deposits. Individual channels range from moderate to high sinuosity and are up to 2-3 km wide. Channel fills can be single-stage or multi-stage fill. In the latter channel type leveed channel complexes are said to exist. In many instances channel meander evolution is characterized by aggradation and down-system meander loop migration. The result of
