The print edition is published as 2 hardback volumes, parts A and B, and sold as a set. The Carboniferous was the time of the assembly of Pangaea by the collision of the Gondwanan and Larussian supercontinents, and the principal interval of the late Paleozoic ice ages. These tectonic and climatic events caused dramatic sea-level fluctuations and climate changes and produced a Carboniferous world that was diverse topographically and climatologically, perhaps only rivalled in that diversity by the late Cenozoic world. Furthermore, the Carboniferous was a time of the accumulation of vast coal deposits of great economic and societal significance. The temporal ordering of geological and biotic events during Carboniferous time thus is critical to the interpretation of some unique and pivotal events in Earth history. This temporal ordering is based on the Carboniferous timescale, which has been developed and refined for nearly two centuries. This book reviews the history of the development of the Carboniferous chronostratigraphic scale and includes comprehensive analyses of Carboniferous radioisotopic ages, magnetostratigraphy, isotope-based correlations, cyclostratigraphy and timescale-relevant marine and non-marine biostratigraphy and biochronology.
The bromide "nothing is constant but change" could have been coined to describe the geological history of the Permo-Carboniferous - the Mississippian, Pennsylvanian, and Permian Periods. Global tectonics, fluctuations in atmospheric and oceanic chemistry, changes in global climate, and evolutionary changes in survivors of mass extinctions created the backdrop for the shifting panorama of the remarkable time in earth history. Catastrophic extinctions during the Frasnian-Famennian crisis decimated the global plant and animal populations, leaving survivors to initally struggle through the Devonian-Carboniferous transition. The ensuing evolutionary diversification into less-populated niches was brought to an abrupt end at the close of the Permian Period by the largest of all mass extinctions. Upheavals in plate motion change the configuration of continents and oceans during this time. Within the evolving Permo-Carboniferous "landscape," a wide diversity of carbonate platforms and reefs flourished. They ranged in size from small mounds to mega-platforms, some of which are important mineral and petroleum reservoirs. It is the diversity which Permo-Carboniferous rocks offer that has led to their intensive study by researchers from industry and academia around the globe. This book stems mostly from presentations given at the SEPM- and IAS-sponsored research conference Permo-Carboniferous Carbonate Platforms and Reefs, held May 12-19, 2000 in El Paso, Texas.
The Bulletin of the Atomic Scientists is the premier public resource on scientific and technological developments that impact global security. Founded by Manhattan Project Scientists, the Bulletin's iconic "Doomsday Clock" stimulates solutions for a safer world.
The Encyclopedia of Caves and Karst Science contains 350 alphabetically arranged entries. The topics include cave and karst geoscience, cave archaeology and human use of caves, art in caves, hydrology and groundwater, cave and karst history, and conservation and management. The Encyclopedia is extensively illustrated with photographs, maps, diagrams, and tables, and has thematic content lists and a comprehensive index to facilitate searching and browsing.
Often regarded as the 'Cinderella' of palaeontological studies, palaeobotany has a history that contains some fascinating insights into scientific endeavour, especially by palaeontologists who were perusing a personal interest rather than a career. The problems of maintaining research facilities in universities, especially in the modern era, are described and reveal a noticeable absence of a national UK strategy to preserve centres of excellence in an avowedly specialist area. Accounts of some of the pioneers demonstrate the importance of collaboration between taxonomists and illustrators. The importance of palaeobotany in the rise of geoconservation is outlined, as well as the significant and influential role of women in the discipline. Although this volume has a predominantly UK focus, two very interesting studies outline the history of palaeobotanical work in Argentina and China.
This book is the first to describe the history of geoconservation. It draws on experience from the UK, Europe and further afield, to explore topics including: what is geoconservation; where, when and how did it start; who was responsible; and how has it differed across the world? Geological and geomorphological features, processes, sites and specimens, provide a resource of immense scientific and educational importance. They also form the foundation for the varied and spectacular landscapes that help define national and local identity as well as many of the great tourism destinations. Mankind's activities, including contributing to enhanced climate change, pose many threats to this resource: the importance of safeguarding and managing it for future generations is now widely accepted as part of sustainable development. Geoconservation is an established and growing activity across the world, with more participants and a greater profile than ever before. This volume highlights a history of challenges, set-backs, successes and visionary individuals and provides a sound basis for taking geoconservation into the future.
