Seismic facies mapping and seismic stratigraphic analysis in the northeastern Gulf of Mexico indicate the presence of a middle Miocene fan complex, here termed the M4. This fan complex is interpreted to comprise at least two fourth-order sequences deposited during lowstand by the Mississippi River. Each depositional sequence is well organized in sets of laterally continuous and discontinuous/hummocky seismic reflectors that are interpreted to be sheet-sand lobe, nonleveed channel and distributary channel facies. Sea-floor compensation is shown by east–west migration of the M4 sequences. The average depositional rate across the fan complex was about 0.5 m/1000 yr.
