Cenozoic Foraminifera and Calcareous Nannofossil Biostratigraphy of the Niger Delta


Book Description

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




Calcareous Nannofossil Biostratigraphy


Book Description

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.

This work contains selected papers presented at the IAS-sponsored International Symposium on the Geology of Deltas, held in Port Harcourt, Nigeria in May 1992. Contents: General considerations; Delta facies and architecture; Aspects of sedimentary petrology and diagenesis in deltas; Niger Delta: Exploration and production perspectives, in a total of 21 chapters.




Quaternary Vegetation Dynamics


Book Description

This book celebrates the relaunch of the African Pollen Database, presents state-of-the-art of modern and ancient pollen data from sub-Saharan Africa, and promotes Open Access science. Pollen grains are powerful tools for the study of past vegetation dynamics because they preserve well within sedimentary deposits and have a huge diversity in ornamentation that allows different taxa to be determined. The reconstruction of past vegetation from the examination of ancient pollen records thus can be used to characterize the nature of past landscapes (e.g. abundance of forests vs. grasslands), provide insights into changes in biodiversity, and gain empirical evidence of vegetation response to climatic change and human activity. In this, the 35th Volume of "Palaeoecology of Africa", we bring together new data and extensive synthetic reviews to provide novel insights into the relationships between human evolution, human activity, climate change and vegetation dynamics during the Quaternary, the last 2.6 million years. Current and ongoing climate and land-use change is exerting pressure on modern vegetation formations and threatening the livelihoods and wellbeing of many peoples in Africa. In this book the focus is on the Quaternary because it is during this geological period that the modern vegetation formations developed into their current configurations against a backdrop of high magnitude global climate change (glacial-interglacial cycles), human evolution, and a growing human land-use footprint. In this book the latest information is presented and collated from around the African continent to parameterize past vegetation states, identify the drivers of vegetation change, and assess the vegetation resilience to change. To achieve this research from two broad themes are covered: (i) the present is the key to the past (i.e. studies which improve our understanding of modern environments so that we can better interpret evidence from the past), and (ii) the past is the key to the future (i.e. studies which unlock information on how and why vegetation changed in the past so one can better anticipate trajectories of future change). This Open Access book will provide a strong foundation for future research exploring past ecological, environmental and climatic change within Africa and the surrounding islands. The book is organized regionally (covering western, eastern, central, and southern Africa) and it contains specialized articles focused on particular topics (such as modern pollen-vegetation relationships and fire as a driver of vegetation change), as well as regional and pan-African syntheses drawing together decades of research to assess key scientific questions (including the role of climate in driving vegetation change and the role of vegetation change in human evolution). These articles will be useful to students and teachers from high school to the highest level of university who are interested in the origins and dynamics of vegetation in Africa. Furthermore, it is also meant to provide societally relevant information that can act as an inspiration for the development of sustainable management practices for the future.

The Vegetation of Antarctica through Geological Time


Book Description

The fossil history of plant life in Antarctica is central to our understanding of the evolution of vegetation through geological time and also plays a key role in reconstructing past configurations of the continents and associated climatic conditions. This book provides the only detailed overview of the development of Antarctic vegetation from the Devonian period to the present day, presenting Earth scientists with valuable insights into the break up of the ancient supercontinent of Gondwana. Details of specific floras and ecosystems are provided within the context of changing geological, geographical and environmental conditions, alongside comparisons with contemporaneous and modern ecosystems. The authors demonstrate how palaeobotany contributes to our understanding of the paleoenvironmental changes in the southern hemisphere during this period of Earth history. The book is a complete and up-to-date reference for researchers and students in Antarctic paleobotany and terrestrial paleoecology.
