Seismic Stratigraphy and Global Changes of Sea Level, Part 4<subtitle>Global Cycles of Relative Changes of Sea Level<xref ref-type="fn" rid="ch03-4fn1" /></subtitle>

Papers from a research symposium at the 1975 American Association of Petroleum Geologists and supplemented by later reports became "Seismic Stratigraphy Applications to Hydrocarbon Exploration", one of AAPG's best-selling book publications. Dramatic improvements in seismic imaging were demonstrated, a result of developments in seismic data quality and the processing capability of electronic technology. Twenty-eight articles are grouped into three sections. The first describes principles that both permit and also limit interpretations. The second section presents sixteen articles that describe the qualitative approach to stratigraphic interpretations of reflection records, and the final section presents techniques and examples of modeling. Of particular interest are a series of eleven papers in the second section under the subject heading of "Seismic stratigraphy and global changes of sea level". Prepared by P. R. Vail, R. M. Mitchum and others from Exxon, they describe the regional unconformities and stratigraphic changes resulting from sea level fluctuations, and the manner in which these changes can be interpreted from seismic surveys. For many individuals within the oil industry who purchased this book, it was their first introduction to the modern concept of sequence stratigraphy that would have a major impact on the methodology of petroleum exploration.
