Stratigraphic Disciplines and Sequence Stratigraphy

Course ID: t37151

Since its inception, sequence stratigraphy has become the most commonly used stratigraphic discipline for developing a basinwide correlation framework, yet aspects of its methods and terminology remain controversial. This topic reviews the history and examines the models of base-level change that underlie the concept. The key surfaces (material- and time-based) and the units they delineate (sequences, systems tracts, and parasequences) are explained and exemplified. Hierarchy and causality are discussed in relation to eustacy and tectonics. Sequence stratigraphic principles are applied to correlation and facies analysis in the context of petroleum exploration. The perspective is that of Dr. Ashton Embry.
