Advancing Seismic and Sequence Stratigraphy: Insights from Testing the Fundamentals
 
Session ID#: 42611
Title: Advancing Seismic and Sequence Stratigraphy: Insights from Testing the Fundamentals
Session Type: Oral
Submitter's Email Address: andrew.madofchevron.com
 
Rationale:
Forty years ago, seismic stratigraphy transformed the field of sedimentary geology
by assigning chronostratigraphic significance to seismic reflections; these features
were used to subdivide the stratigraphic record into genetic units, which were mapped
at the scale of sedimentary basins. Although initially rooted in reflection geometry
and in the interpretation of depositional systems, seismic stratigraphy promptly moved
towards interpreting the mechanisms of sequence formation, and in particular the role of
eustasy on modulating the stratigraphic record. Since these early days of sequence stratigraphy,
advances in subsurface and outcrop settings have been aimed at evaluating the role of accommodation,
relative sea-level change, stratal stacking patterns, and more recently, trajectory analysis.
Although these concepts are regularly used, they have rarely been treated as testable hypotheses,
making fundamental assumptions of sequence stratigraphy equivocal. Here, we propose a topical session,
and invite presenters to show their interdisciplinary and solution-driven work, which should focus on
rigorously testing fundamental assumptions of sequence stratigraphy. Presentations should be aimed at
evolving ideas concerning the interpretation of stratal geometries and on their controlling mechanisms,
with the intention of advancing seismic and sequence stratigraphy in both carbonate and clastic depositional settings.
 
Scientific Categories:
Stratigraphy, Sediments, Clastic, Paleoclimatology/Paleoceanography
 
Description:
We invite presenters to show their interdisciplinary and solution-driven work, which should focus on
rigorously testing fundamental assumptions of sequence stratigraphy. Presentations should be aimed at
evolving ideas, with the intention of advancing the science.
 
Comments:
We are proposing a topical session aimed at advancing sequence stratigraphy through cross disciplinary integration.
This session is timely because 2017 marks the forty-year anniversary of the pivotal work on the subject, yet little
has been done to progress sequence stratigraphy since. We envision integrated insights from stratigraphers,
sedimentologists, tectonisists, structural geologists, modelers, climatologists, oceanographers, geochronologists,
and planetary geologists.
