Landscape Evolution of Continental-Scale River Systems: A Case Study of North America's Pre-Pleistocene Bell River Basin provides a detailed case study and complete analysis of this continental-scale North American paleo-river system. The book uses detrital zircon provenance data to link incision of the Grand Canyon to deposition of its erosional products in a giant drowned delta in the Labrador Sea, in the context of sedimentary source-to-sink processes and Plio-Pleistocene continental drainage changes. The case study describes the tectonic changes in this continental-scale paleo-river system, with global implications, and contrasts this system to other continental-scale river systems around the world. This book is a valuable reference for postgraduate students, academics and researchers in the fields of geology, fluvial geomorphology and other geosciences. Readers will be able to use this detailed case study to better understand the implications for how active tectonics of headwaters regions influence delta deposition in continental-scale river systems around the world. - Details the landscape evolution of a continental-scale paleo-river system using detrital zircon geochronology with fluvial processes - Provides a multidisciplinary case study with applications to other continental-scale river systems around the world - Compares and contrasts the Bell river to the Amazon and uses these examples as analogs to discuss other systems

This long-awaited book about non-pollen palynomorphs (NPPs) aims to cover gaps in our knowledge of these abundant but understudied palynological remains. NPPs, such as fungal spores, testate amoebae, dinoflagellate cysts, acritarchs and animal remains, are routinely recovered from palynological preparations of marine or terrestrial material, from Proterozoic to recent geological times. This book gives the reader a comprehensive overview of the different types of NPPs, with examples from diverse time periods and environments. It provides guidance on sample preparation to maximize the recovery of these NPPs, detailed information on their diversity and ecological affinity, clarification on the nomenclature and demonstrates their value as environmental indicators. This volume will become the reference guide for any student, academic or practitioner interested in everything else in their palynological preparations.

Fifty million years ago, the Arctic Ocean was a warm sea, bounded by lush vegetation of the warm-temperate shores of Scandinavia, Siberia, Alaska and the Northwest Territories. Wind and storms were rare because Atlantic weather systems had not developed but, as today, polar day length added a hostile element to this otherwise tranquil climate. With the aid of scientists from all the countries close to the Arctic Circle, this book describes the palaeontology, the statistical analysis of vegetational features, comparisons with atmospheric, marine, and geological features and some of the first models of plant migration developed from newly constructed databases.

An early reviewer of this book stated that he had difficulty assessing its marketability because it "falls between the cracks" of geological literature. We have designed this book to meet a need of modem geology: namely, a single source providing both detailed and synoptic stratigraphy of the various regions of North America, through geological time. Shortly after beginning work on such a book, we realized why it had not yet been written: it required six years of effort, assimilation of an incredible amount of information, and two years' additional work to cut the volume down to publishable size. Further, by the time the final chapter was written, the fIrst few were already out of date. Nevertheless, the book lies in front of you. It is intended to serve several purposes. As a textbook, it will serve the following courses: • Regional stratigraphy • Sedimentary tectonics • Regional tectonics • Advanced historical geology • Survey-level paleontology Obviously, not all portions of the book are relevant to all of the above courses. We assume the reader will retain this book after the particular course is done, and will use it as a reference book. Hopefully, others will obtain the book solely for reference purposes. We believe it will be especially useful for the working geologist or academic geologist seeking generalized and some moderately detailed information about a region or geological time interval which is unfamiliar.

This book provides complete coverage of all aspects of the study of all fossil palynomorphs yet studied. It is a profusely illustrated treatment. The book serves both as a student text and general reference work. Palynomorphs yield information about age, geological and biological environment, climate during deposition, and other significant factors about the enclosing rocks. Extant spores and pollen are treated first, preparing the student for more difficult work with fossil sporomorphs and other kinds of palynomorphs. An appendix describes laboratory methods. The glossary, bibliographies and index are useful tools for study of the literature.
