Seismoacoustic Study of the Shallow Gas Transport and ... - E-LIB

Chapter 4
River fan deposits. Being trapped by the hemipelagic fine-grained sediment layers
on the top of the Paleo-Don River fan deposits, numerous shallow gas reservoirs
have formed. Finally, shallow faults, probably formed within the uppermost units
due to slope instability and/or earthquakes, can serve as vertical migration
pathways above these gas reservoirs for free gas to the seafloor and through the
observed gas flares into the water column.
