A seismic sequence is defined as the stratigraphic interval between two consecutive sequence boundaries, representing two marine regression events with a marine transgression event at the middle. Thus a seismic sequence is further subdivided with a basal unit of regressive systems tract, a transgressive systems tract at the middle, and a ...
The definition of a type 1 and type 2 sequence was first introduced by Vail et al. (1984). [4] Since they were hard to recognize, they were redefined in 1990 by Van Wagoner et al.. However even with this new definition, type 2 sequence boundaries were hard to recognize in the field due to their lack of subaerial exposure.
In sequence stratigraphy, a maximum flooding surface is the surface that marks the transition from a transgression to a regression. [1] Maximum flooding surfaces are abbreviated by mfs, synonyms for them include final transgressive surface, surface of maximum transgression and maximum transgressive surface. [2]
Condensed sections, as the best chronological markers, are primary important in stratigraphic correlation, between shallow and deep marine depositional environments. Furthermore, they play a fundamental role in identifying systems tracts to predict depositional facies changes and the associated lithological variations [ 6 ] .
A parasequence is defined as a genetically related succession of bedsets that is bounded by marine flooding surfaces (or their correlative surfaces) on top and at the bottom. [1]
Sequence stratigraphy, the study of sea level change through the examination of sedimentary deposits, was developed from the centuries-old controversy over the origin of cyclic sedimentation and the relative importance of eustatic and tectonic factors on sea level change.
Accommodation is a fundamental concept in sequence stratigraphy, a subdiscipline of geology.It is defined as the space that is available for the deposition of sediments. [1] [2] Accommodation space can be pictured as the volume between the actual surface and the theoretical equilibrium surface where deposition and erosion are in balance at every point.
