This page introduces the methodology of sequence stratigraphy as applied to sediment accumulation in continental, marginal marine, basin margin, and down slope settings. Associated pages demonstrate how sequence stratigraphy subdivides the sedimentary section into a framework of erosional, depositional and non-depositional surfaces. Pages explain how the surfaces are generated when the relative position of the sea changes, enclose genetically related stratigraphic facies geometries that enable the interpretation and the prediction of extent of sedimentary facies geometry, lithologic character, grain size, sorting and quality of porosity and permeability away from control points. Reconstruction of depositional setting and paleogeography are facilitated by the framework of sequence stratigraphy.
Modules: sequence stratigraphy course notes & exercises for students, professors and those who teach professional short courses in this topic.

Sequence stratigraphic movie (to view click on image below)
This Sedpak movie captures a sedimentary section subdivided into geometric packages defined by bounding unconformities and internal surfaces that result from varying positions of relative sea level and rates of sedimentation. These geometries demonstrate why sequence stratigraphic analyses of seismic cross-sections, well logs and outcrop studies of sedimentary rock are used to predict the thickness and extent of sediment lithology from inferences built from this understanding of how sediment geometry changes with relative sea level and rates of sedimentation.
