Sequence stratigraphy is a branch of geology, specifically a branch of stratigraphy, that attempts to discern and understand historic geology through time by subdividing and linking sedimentary deposits into unconformity bounded units on a variety of scales.
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 a more rigorous and general way, a sequence is defined as a "relatively conformable [...], genetically related succession of strata bounded by unconformities or their correlative surfaces" [ 2 ] Special cases and related concepts
Stratigraphy is a branch of geology concerned with the study of rock layers and layering (stratification). It is primarily used in the study of sedimentary and layered volcanic rocks . Stratigraphy has three related subfields: lithostratigraphy (lithologic stratigraphy), biostratigraphy (biologic stratigraphy), and chronostratigraphy ...
A parasequence is a fundamental concept of sequence stratigraphy. Parasequences are not directly related to sequences. Definition A ...
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.
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 .
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.
