Stratigraphy

This book, written by 33 stratigraphic experts, presents various processes available which will enable the location in time of all rock types: sedimentary, metamorphic, plutonic, and eruptive, whether they are in outcrop or at subsurface. The terminology and the appropriate practices for each method are presented in separate chapters and illustrated with concrete examples. The order of the chapters is modeled on the progression of the stratigraphic process, from the descriptive to the interpretative, from the methods of the geometric stratigraphy (lithostratigraphy and genetic stratigraphy, chemostratigraphy, magnetostratigraphy) to the chronological stratigraphy (biostratigraphy), followed by the chronometric stratigraphy (isotopic geochronology). The final two chapters are dedicated to chronostratigraphic units and correlations which combine the contributions of various methods and to the presentation of the 2007 version of the Geological Time Scale. The definitions of stratigraphic terms can be found in a glossary at the end of the work. The book is addressed to all professional geologists, from the industrial sector as well as those in universities, including teachers and researchers who would like to deepen their knowledge of the vocabulary, the concepts, the methods and the practical applications of different approaches of stratigraphy, a reference discipline for the entirety of the geological sciences.

The innovation and refinement of the techniques and concepts ofsequence stratigraphy has been one of the most exciting andprofound developments in geology over the past thirty years.Seismic stratigraphy has now become one of the standard tools ofthe geoscientist, and there is a pressing need for an introductorytext on sequence stratigraphy. This new book sets out to define andexplain the concepts, principles and applications of thisremarkably influential approach to the study of sedimentary strata.The authors take a rigorous objective stance in evaluating thetechniques and interpretation of sequence stratigraphy - basing thetext on an internal training course developed by British Petroleum(BP). A new text on this increasingly important field A practical guide based on the experience of practisingsequence stratigraphers Based on a highly successful BP training course

This volume presents the proceedings of Symposium I "Stratigraphy" of the 30th International Geological Congress at Beijing. The proceedings aim to present a view of contemporary geology and should be of interest to researchers in the geological sciences.

Every little wiggle has a meaning all its own. This is our underlying faith, that details of seismic waveshapes can tell us the details of the nature of the earth. But their voices are obscured by many irrelevancies. They speak in a high-noise environment, and we have been able to decipher only a small portion. However, things are looking up: better tech niques are lessening the irrelevancies, and we are learning to read. In exploration of unknown areas, determining the nature of the rocks present is often the difficult aspect. Most of the properties of rocks that can be measured at a distance are not distinctive enough to identify the rock unambiguously. Con ventionally, seismic data are used to determine aspects of the structure. Stratigraphic pictures are inferred from the struc ture, the nature of rocks exposed for examination in the sur rounding area, and regional concepts. Three points make seismic stratigraphy feasible now: (1) we have better data quality, (2) we have begun to sys tematize analysis procedures, and (3) we believe in the geologic significance of waveshape details.

Sequence stratigraphy has become a powerful tool in the basin analysis of the North Sea Basin, and will continue to play an important role in the maximization of the remaining hydrocarbon potential of the region, whilst also supporting the energy transition in carbon capture and storage projects with Jurassic storage units. This Memoir provides a long-awaited, comprehensive documentation of Jurassic to lowermost Cretaceous sequence stratigraphy of the region (UK, Norway, Denmark and adjacent areas). The volume is amply illustrated by numerous well log displays, core images, seismic lines, chronostratigraphic diagrams and outcrop photographs. Individual chapters discuss the historical usage of sequence stratigraphy in the North Sea Jurassic, sequence stratigraphic concepts and models, application in hydrocarbon field development, definition of stratigraphic traps, well sequence interpretation methodology and controls on sequence development. To complete the volume there are further chapters on North Sea Jurassic lithostratigraphy and its relation to sequence stratigraphy, and descriptions of the biozones used to characterize and correlate the sequences.
