Genetic
(R-T) Sequences
(Galloway,
1989a&b)
• Stratigraphic Record
Consists of Regressive-Transgressive (R-T) Cycles (Genetic Sequences)
• Genetic Sequences are
bounded by Maximum Flooding Surfaces
• These surfaces are distinctive (logs/fauna)
and easily mappable (laterally continuous)
• In this paradigm, mfs’s are
discontinuities
• Traditional boundaries mapped on Seismic in
Deep Water Basins around the World
Transgressive Deposits
