Depositional
Sequence
Hierarchy of Stratal Surfaces (bed,
bedset, parasequence, parasequence set, etc.)
Depositional Sequences contain 3
distinct stratal compartments (Systems
Tracts)
Key Stratal Surfaces (Sequence Boundaries,
Transgressive & Maximum Flooding Surfaces) define systems tracts
Transgressive and maximum flooding
surfaces are not disconformities (surfaces)
