Fluvial Sequence Stratigraphy
Sequence stratigraphy was developed in the late 1970’s and synthesized in the AAPG memoir 26 (Payton, 1977). Initially the concept was designed to cope with the shallow marine to deltaic interval of the sedimentary system, but has since been expanded into the deeper marine realm and into fluvial to alluvial settings. Whatever the setting, sequence stratigraphy provides a useful toolbox for stratigraphic analysis, the identification of timelines, prediction of facies distribution and necessitates thinking about the allogenic forces acting on the basin. Sequence stratigraphy relies on the recognition of genetically related strata (eg. deposited during a specific interplay between the rate of accommodation creation or destruction and the rate of sedimentation) bounded by unconformities or their correlative conformities. Although unconformable surfaces may be time diachronous, they can usually be related to a single “event” in geological time, if this event is related to a mayor allogenic force, then the identification of such a surface will be key to successful correlation.
Below you can find a link is an essay and explanation of Fluvial Sequence Stratigraphy. It tackles important principles and pitfalls and focuses on the fluvial character with respect to base-level and climate. Descriptive diagrams and figure are included and I hope you find this useful and comments are very welcome!
