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.

This Memoir covers one of the most important and active exploration reservoirs being pursued by geoscientists worldwide: fine-grained turbidite systems. 28 chapters show the results of an intense research effort in the 1990s that resulted from the discovery of large hydrocarbon accumulations in fine-grained turbidite systems in Brazil, the Gulf of Mexico, West Africa, and the North Sea. Industry and academia have joined together in this publication and the result is a unique opportunity to study these turbidite systems from the outcrop to the modeling; through the interpretation with 2-D and 3-D seismic data; to case histories and analog studies from Arkansas and Oklahoma, South and West Africa, Gulf of Mexico, west Texas, and New Zealand.
