Stratigraphy has come to be indispensable to nearly all branches of the earth sciences, assisting such endeavors as charting the course of evolution, understanding ancient ecosystems, and furnishing data pivotal to finding strategic mineral resources. This book focuses on traditional and innovative stratigraphy techniques and how these can be used to reconstruct the geological history of sedimentary basins and in solving manifold geological problems and phenomena.

"In the last twenty years or so there has been an upsurge in the study of Palaeozoic fishes for solving geological problems, both in areas of biostratigraphy and biogeography. This has resulted in an explosion of data, much of it so new that it will take years for all the recent discoveries to be published. This book has resulted to fill the need to provide up-to-date summaries of global work in progress showing the application of both macroscopic and microscopic remains of Palaeozoic vertebrates to geological correlations, and to refinement of global palaeogeographic reconstructions."--from the Preface. This book offers the first detailed treatment of palaeozoic vertebrates for use in correlations and in biogeographic studies. With thirteen chapters of systematic analysis of biostratigraphic and biogeographic data, it includes invaluable summaries of current research as well as new and significant contributions to the fields of geology and evolutionary biology. With charts and figures that show many of the important fossils discussed in the text, as well as stratigraphic, location, and taxonomic indexes, the book will interest palaeontologists, stratigraphers, and other earth scientists concerned with the early history of life on earth.

The Michigan Basin is a classic intracratonic basin that has played a significant role in the fundamental understanding of geological processes in such basins, and has been an important resource for oil and gas, economic minerals, groundwater, and coal. Despite the classic nature of the Michigan Basin, there has not been a "special volume" dedicated to the basin in nearly 25 years. Since that time, new advancements in the geological sciences, particularly the utilization of high-resolution sequence stratigraphy and three-dimensional geostatistical modeling, have led to a new and more comprehensive understanding of the Paleozoic sedimentary packages of the Michigan Basin. This volume provides significant new insights of the Michigan Basin to both academic and applied geoscientists; it includes papers that discuss various aspects of the sedimentology and stratigraphy of key units within the basin, as well as papers that analyze the diverse distribution of natural resources present in this basin.

It has been more than a decade since the appearance of the First Edition of this book. Much progress has been made, but some controversies remain. The original ideas of Sloss and of Vail (building on the early work of Blackwelder, Grabau, Ulrich, Levorsen and others) that the stratigraphic record could be subdivided into sequences, and that these sequences store essential information about basin-forming and subsidence processes, remains as powerful an idea as when it was first formulated. The definition and mapping of sequences has become a standard part of the basin analysis process. The main purpose of this book remains the same as it was for the first edition, that is, to situate sequences within the broader context of geological processes, and to answer the question: why do sequences form? Geoscientists might thereby be better equipped to extract the maximum information from the record of sequences in a given basin or region. Tectonic, climatic and other mechanisms are the generating mechanisms for sequences ranging over a wide range of times scales, from hundreds of millions of years to the high-frequency sequences formed by cyclic processes lasting a few tens of thousands of years
