This chapter briefly reviews some practical guidelines for sequence-stratigraphic analysis, with an emphasis on borehole data. As the previous chapters have discussed, the log and facies characteristics of key surfaces and systems tracts vary considerably with paleogeographic location within a basin. Also, as discussed, basin physiography and coastal morphology play an important role in that they control the kind of depositional environment that develops (e.g., wave-dominated versus river-dominated deltaic systems). Thus, in order to fully exploit the sequence stratigraphic approach for basin-fill analysis, it is essential to have a firm understanding of the interplay between sea-level change, coastal physiography, sediment flux, and sedimentary processes. When done properly, the sequence-stratigraphic approach can yield as many new questions as answers. However, these new questions can lead to previously unthought-of geologic solutions. In this way, the sequence-stratigraphic approach constitutes a powerful tool for the generation of reasonable geological working hypotheses.

Siliciclastic Sequence Stratigraphy—Concepts and Applications
Siliciclastic Sequence Stratigraphy-Concepts and Applications - Sequence stratigraphy has experienced a virtual explosion of applications in recent years. During that time, the concepts upon which sequence stratigraphy is based have been evolving to conform to new observations as well as new types of data. This volume summarizes the current status of this discipline as it applies to siliciclastic deposits. The emphasis in this volume is on sequence stratigraphy as an ?approach? to geological analysis, rather than as a model to which all data sets must conform. The expression of sequence architecture and the nature of bounding surfaces is illustrated through examples and applications drawn from a range of data types, including outcrop, core, wireline log, and 3-D seismic data. In addition, sequence expression also is illustrated using examples of modern landforms.
