An Online Guide to Sequence Stratigraphy

This online guide is primarily aimed at the application of sequence stratigraphy to outcrops. As a result, none of the examples deal with topics related specifically to cores, well logs, or most significantly, seismic. Perhaps the best way to work through this online guide is to start with accommodation and to continue down the list of topics from there. Many of the illustrations in this online introduction to sequence stratigraphy are modified from the figures in Van Wagoner et al.’s Siliciclastic Sequence Stratigraphy in Well Logs, Cores, and Outcrops (AAPG Methods in Exploration #7). Interested readers should study that reference and other references in the Further Reading section for a fuller explanation of the concepts introduced here.
