Cenozoic Foraminifera and Calcareous Nannofossil Biostratigraphy of the Niger Delta is available just as exploration and production activities are moving into the little known deep water terrain of the Niger Delta. A thorough understanding of the Cenozoic Niger Delta will improve understanding and exploration of the evolution of deeper offshore belts, help researchers strengthen and refine existing Neogene nannofossil biostratigraphic schemes for the Niger Delta region, and gain a better understanding of the relationship between nannofossil assemblage variations and paleoenvironments. The hydrocarbon reserves of the Niger Delta are an extremely valuable natural resource. Biostratigraphy and Correlation play important roles in the discovery, development and maturing of hydrocarbon fields. Calcareous nannofossils have been important tools for the stratigraphers in the Niger Delta and in recent years exploration has moved into deeper offshore areas where nannofossils are more abundant and diverse. Little has been published about the calcareous nannofossil chronostratigraphy of the Niger delta. Cenozoic Foraminifera and Calcareous Nannofossil Biostratigraphy of the Niger Delta fills the gap for earth scientists and those working in the oil and gas industry. - Showcases the phylogenetic relationships of some of the principal Niger Delta marker species and their biostratigraphic and biochronologic significance - Features photographs of index benthonic foraminifera and their equivalent planktonic datums as well as environmentally sensitive species used in paleobathymetric reconstruction - Includes information and research that has, until now, been in the private archives of operational companies - Companion website features 20+ full color stratigraphic charts and maps

The Early-Middle Pleistocene transition (around 1.2 to 0.5 Ma) marks a profound shift in Earth's climate state. Low-amplitude 41 ka climate cycles, dominating the earlier part of the Pleistocene, gave way progressively to a 100 ka rhythm of increased amplitude that characterizes our present glacial-interglacial world. This volume assesses the biotic and physical response to this transition both on land and in the oceans: indeed it examines the very nature of Quaternary climate change. Milankovitch theory, palaeoceanography using isotopes and microfossils, marine organic geochemistry, tephrochronology, the record of loess and soil deposition, terrestrial vegetational change, and the migration and evolution of hominins as well as other large and small mammals, are all considered. These themes combine to explore the very origins of our present biota.

Calcareous nannofossils are an exceptionally important microfossil group, with their living counterparts, coccolithopores, representing one of the major components of phytoplankton in present day oceans. Their abundant fossil record and world-wide distribution has led to their rapid acceptance as one of the most important index-fossil groups in stratigraphical research. The first two chapters of this book provide general information concerning calcareous nannofossils, including reviews of their biology and palaeobiology, and preparation and observation techniques. Chapters 3-9 are ordered stratigraphically, and present state-of-the-art summaries of calcareous nannofossil biostratigraphy for each time period, with comprehensive illustrations of all taxa within a standardised classification based on the latest research into structure and biomineralization. The practical application of these biostratigraphic schemes is discussed, including comments on zones biogeography, taxonomy and evolution. This information is internationally relevant, and global correlation is discussed. Calcareous Nannofossil Biostratigraphy is the most comprehensive atlas of this fossil group ever produced, containing 65 full page plates with over 2,000 individual photographs, together with comments concerning stratigraphic distribution and identification. Chapters on the Mesozoic contain electron microscope illustrations as well as light micrographs. The inclusion of much recent, previously unpublished, research provides a new level of biostratigraphic resolution for a number of time periods, making the book both a valuable synthesis and a significant step forward in biogeographical research. Calcareous Nannofossil Biostratigraphy is a comprehensive practical handbook for palaeontologists and organizations who use calcareous nannofossils in biostratigraphy, and provides a valuable practical reference work for earth scientists engaged in stratigraphic research, and those interested in palaeontology, palaeoceanography, stratigraphy and geochronology.

Geologic Time Scale 2020 (2 volume set) contains contributions from 80+ leading scientists who present syntheses in an easy-to-understand format that includes numerous color charts, maps and photographs. In addition to detailed overviews of chronostratigraphy, evolution, geochemistry, sequence stratigraphy and planetary geology, the GTS2020 volumes have separate chapters on each geologic period with compilations of the history of divisions, the current GSSPs (global boundary stratotypes), detailed bio-geochem-sequence correlation charts, and derivation of the age models. The authors are on the forefront of chronostratigraphic research and initiatives surrounding the creation of an international geologic time scale. The included charts display the most up-to-date, international standard as ratified by the International Commission on Stratigraphy and the International Union of Geological Sciences. As the framework for deciphering the history of our planet Earth, this book is essential for practicing Earth Scientists and academics. - Completely updated geologic time scale - Provides the most detailed integrated geologic time scale available that compiles and synthesize information in one reference - Gives insights on the construction, strengths and limitations of the geological time scale that greatly enhances its function and its utility

This comprehensive synthesis of our knowledge of the biostratigraphy of marine plankton is the work of an international team of eighteen authors. It covers all the major fossil groups that can be used to date sediments and rocks in the time interval Late Mesozoic to Holocene. Altogether more than 3200 taxa are considered, almost all of which are illustrated and depicted on range charts, making the book a valuable work of reference in the earth sciences. For ease of reference by specialists interested in either calcareous or non-calcareous microfossils, the original work is now divided into two independent volumes. Volume I covers the calcareous microfossils and includes planktic foraminifers, calcareous nannofossils and calpionellids.
