Permian and Triassic are the interval known for the integration and separation of Pangea, the closure of the Palaeotethys and the opening of Mesotethys. They were associated with a series of worldwide events including the Late Palaeozoic glaciation and succeeding extensive evaporatic and reef formations, the end-Palaeozoic regression, strong orogenies and widespread volcanism and magmatism, and finally, the Permo-Triassic biotic macro-extinction. These events resulted in the formation of enormous reserves of coal, petroleum, evaporites, phosphorites and metal resources. The Permian and Triassic thus constitutes a time interval particularly important both for understanding the Earth's history and for exploration of mineral resources.The book aims to reconstruct the Permian-Triassic history of Pangea, Palaeo-Tethys and Palaeo-Pacific through stratigraphic, palaeogeographic and other interdisciplinary approaches. It consists of two parts. Part 1 deals with regional stratigraphy of Tethyan and western Circum-Pacific countries which is the basis for interregional correlation, and palaeogeography. Part 2 deals with the biotic evolution at the Permian-Triassic transition, focusing on the major invertebrate groups: foraminifers, radiolarians, brachiopods, ammonoids and conodonts.

The culmination of more than fifty years of research by the foremost living expert on plant classification, Diversity and Classification of Flowering Plants is an important contribution to the field of plant taxonomy. In the last decade, the system of classifying plants has been thoroughly revised. Instead of describing every individual family, Takhtajan includes descriptions in keys to families, which he calls "descriptive keys." The advantage of descriptive keys is that they give both the characteristic features of the families and their differences. The delimitation of families and orders drastically differs from the one accepted by the Englerian school and from the one accepted in Arthur Cronquist's system. Takhtajan favors the smaller, more natural families and orders, which are more coherent and better-defined, where characters are easily grasped, and which are more suitable for information retrieval and phylogenetic studies, including cladistic analysis (because it reduces polymorphic codings).

A compendium of papers first presented at the fifteenth annual International Congress on Carboniferous and Permian Stratigraphy, this book offers an overview of the latest research on rock formation that took place over 250 million years ago. This ancient sediment, which provides much of the mineral resources we use today, is a key indicator of massive environmental shifts that occurred around the creation of the super-continent Pangea. Organized thematically, the book covers a wide variety of topics, including the structural development of Carboniferous basins, the paleontology of those periods, and Carboniferous and Permian timescales and global correlations. As the contributors demonstrate, a better understanding of the evolution of the earth during the Carboniferous and Permian periods will not only help us find more mineral resources, but will also provide insight into important modern environmental questions.

Future Climates of the World: A Modelling Perspective is Volume 16 of the highly prestigious series of climatology reference books World Survey of Climatology. The present volume offers a state-of-the-art overview of our understanding of future climates and is aimed at climatology undergraduates, interested non-climatologists with a scientific background as well as the generally interested reader. Each topic is discussed clearly so that the full implications of its affect on the earth's future climate can be fully understood. The study of climate has moved from data collection ``climatology'' to the model and experimentally based predictions of ``climatic science''. Our understanding of climatic prediction depends crucially upon improvements in, and improved understanding of, climatic models. The book compises four main themes which follow an introductory chapter i.e. the geologic perspective (I) and present-day observations (II) as they pertain to future climates; human factors affecting future climates (III) and planetary geophysiology and future climates (IV).

Impact cratering is an important geological process on all solid planetary bodies, and, in the case of Earth, may have had major climatic and biological effects. Most terrestrial impact craters have been erased or modified beyond recognition. However, major impacts throw ejecta over large areas of the Earth's surface. Recognition of these impact ejecta layers can help fill in the gaps in the terrestrial cratering record and at the same time provide direct correlation between major impacts and other geological events, such as climatic changes and mass extinctions. This book provides the first summary of known distal impact ejecta layers
