Far less well-known is a much greater catastrophe that took place at the end of the Permian period 251 million years ago: 90 percent of life was destroyed, including saber-toothed reptiles and their rhinoceros-sized prey on land, as well as vast numbers of fish and other species in the sea.This book documents not only what happened during this gigantic mass extinction but also the recent rekindling of the idea of catastrophism. Was the end-Permian event caused by the impact of a huge meteorite or comet, or by prolonged volcanic eruption in Siberia? The evidence has been accumulating through the 1990s and into the new millennium, and Michael Benton gives his verdict at the very end. From field camps in Greenland and Russia to the laboratory bench, When Life Nearly Died involves geologists, paleontologists, environmental modelers, geochemists, astronomers, and experts on biodiversity and conservation. Their working methods are vividly described and explained, and the current disputes are revealed. The implications of our understanding of crises in the past for the current biodiversity crisis are also presented in detail. 46 b/w illustrations.

    Written by a passionate and professional geologist who has spent countless hours in the field exploring and photographing the state, In Search of Ancient Oregon is a book for all those interested in Oregon's landscapes and environments. It presents fine-art-quality color photographs of well-known features such as Mount Hood, Crater Lake, Smith Rock, Steens Mountain, the Columbia River Gorge, and Cannon Beach, and scenic, not so well known places such as Jordan Craters, Leslie Gulch, Abert Rim, Hells Canyon, Elkhorn Mountains, and Three Fingered Jack. Each of the more than 220 stunning photographs is accompanied by readable text, presenting the story of how Oregon's diverse landscapes evolved — and what we may expect in the future. Until now, no book has presented this dynamic story in a way that everyone interested in Oregon's natural history can easily understand. The combination of extraordinary photographs and the author's lucid explanations make this book both unique and essential for those curious about our own contemporary landscape.

    The author, one of the most profound specialists in the field of volcanology, explains in a concise and easy to understand manner the basics and most recent findings in the field. Based on over 300 color figures and the model of plate tectonics, the book offers insight into the generation of magmas and the occurrence and origin of volcanoes. The analysis and description of volcanic structures is followed by process oriented chapters discussing the role of magmatic gases as well as explosive mechanisms and sedimentation of volcanic material. The final chapters deal with the forecast of eruptions and their influence on climate. Students and scientists of a broad range of fields will use this book as an interesting and attractive source of information. Laypeople will find it a highly accessible and graphically beautiful way to acquire a state-of-the-art foundation in this fascinating field."Volcanism by Hans-Ulrich Schmincke has photos of the best quality I have ever seen in a text on the subject In addition, the schematic figures in their wide range of styles are clear, colorful, and simplified to emphasize the most important factors while including all significant features"I have really enjoyed reading and rereading Schmincke s book. It fills a great gap in texts available for teaching any basic course in volcanology. No other book I know of has the depth and breadth of VolcanismI have shared Volcanism with my colleagues to their significant benefit, and I am more convinced of its value for a broad range of Earth and planetary scientists.Undoubtedly, I will use Volcanism for my upcoming courses in volcanology. I will never hesitate to recommend it to others. Many geoscientists from very different subdisciplines will benefit from adding the book to their personal libraries. Schmincke has done us all a great service by undertaking the grueling task of writing the book and it is much better that he alone wrote it." Stanley N. Williams, ASU Tempe, AZ (Physics Today, April 2005)"Schmincke is a German volcanologist with an international reputation, and he has done us all a great favour because he sensibly channelled his fascination with volcanoes into writing this beautifully illustrated book... [he] tackles the entire geological setting of volcanoes within the earth and the processes that form them... And, with more than 400 colour illustrations, including a huge number of really excellent new diagrams, cutaway models and maps, plus a rich glossary and references, this book is accessible to anyone with an interest in the subject." New Scientist (March 2004)"The science of volcanology has made tremendous progress over the past 40 years, primarily because of technological advances and because each tragic eruption has led researchers to recognize the processes behind such serious hazards. Yet scientists are still learning a great deal because of photographs that either capture those processes in action or show us the critical factors left behind in the rock record.Volcanism by Hans-Ulrich Schmincke has photos of the best quality I have ever seen in a text on the subject. I found myself wishing that I had had the photo of Nicaragua s Masaya volcano, which was the subject of my dissertation, but it was Schmincke who was able to include it in his book. In addition, the schematic figures in their wide range of styles are clear, colorful, and simplified to emphasize the most important factors while including all significant features. The book s paper is of such high quality that at times I felt I had turned two pages rather than one.I have really enjoyed reading and rereading Schmincke s book. It fills a great gap in texts available for teaching any basic course in volcanology. No other book I know of has the depth and breadth of Volcanism. I was disappointed that the text did not arrive on my desk until last August, when it was too late for me to choose it for my course in volcanology. I am also disappointed about another fact the book s binding is already becoming tattered because of my intense use of it!Schmincke is a volcanologist who, in 1967, first published papers on sedimentary rocks of volcanic origin, the direction traveled by lava flows millions of years ago, and the structures preserved in explosive ignimbrites, or pumice-flow deposits, that reveal important details of their formation. Since then, his studies in Germany s Laacher See, the Canary Islands, the Troodos Ophiolite of Cyprus, and many other regions have forged great fundamental advances. Such contributions have been recognized with his receipt of several international awards and clearly give him a strong base for writing the book.However, as a scientist who has focused on the challenges of monitoring the very diverse activities of volcanoes, I think that the text s overriding emphasis on the rock record has its cost. The group of scientists who are struggling with their goals to reduce or mitigate the hazards of the eruptions of tomorrow need to learn more about the options of technology, instrumentation, and methodology that are currently available. More than 500 million people live near the more than 1500 known active volcanoes and are constantly facing serious threats of eruptions. An extremely energetic earthquake caused the horrific tsunamis of 2004. However, the tsunamis of 1792, 1815, and 1883, which were caused by the eruptions of Japan s Unzen volcano and Indonesia s Tambora and Krakatau volcanoes, each took a similar toll. "( Stanley N. Williams, PHYSICS TODAY, April 2005)"

    With no cover of ice or snow and no rainfall, these dry valleys are "islands" in the midst of the frozen ice of the Antarctic continent, a strange environment of ice-covered lakes that hold some of the planet's purest water, huge expanses of wind-sculpted rock, barren eroded land forms and glaciers that intrude into the edges of the valleys. Access to this unique environment is extremely restricted. This book is built around the landscape photographs of Craig Potton, who gathered the images on two separate trips to Antarctica. The text is provided by Bill Green whose previous non-fiction writing on the Dry Valleys won him the John Burroughs Medal for nature writing in the USA.

    The first-ever comprehensive history of the study of such igneous rocks, it traces the development of igneous petrology from ancient descriptions of volcanic eruptions to recent work incorporating insights from physical chemistry, isotope studies, and fluid dynamics.Intellectual developments in the field--from the application of scientific methods to the study of rocks to the discovery of critical data and the development of the field's major theories--are considered within their broader geographical, social, and technological contexts. Mind over Magma examines the spread of igneous petrology from western Europe to North America, South Africa, Japan, Australia, and much of the rest of the world. It considers the professionalization and Anglicization of the field, detailing changes in publication outlets, the role of women, and the influence of government funding. The book also highlights the significant role that technological developments--including the polarizing microscope, high-temperature quenching furnaces, and instrumental analysis--have played in the discovery of new data and development of revolutionary insights into the nature of igneous rocks.Both an engagingly told story and a major reference, Mind over Magma is the only available history of this important field. As such, it will be appreciated by petrologists, geochemists, and other geologists as well as by those interested in the history of science.

    But in the full history of life, ancient animals, even the trilobites, form only the half-billion-year tip of a nearly four-billion-year iceberg. Andrew Knoll explores the deep history of life from its origins on a young planet to the incredible Cambrian explosion, presenting a compelling new explanation for the emergence of biological novelty. The very latest discoveries in paleontology--many of them made by the author and his students--are integrated with emerging insights from molecular biology and earth system science to forge a broad understanding of how the biological diversity that surrounds us came to be. Moving from Siberia to Namibia to the Bahamas, Knoll shows how life and environment have evolved together through Earth's history. Innovations in biology have helped shape our air and oceans, and, just as surely, environmental change has influenced the course of evolution, repeatedly closing off opportunities for some species while opening avenues for others. Readers go into the field to confront fossils, enter the lab to discern the inner workings of cells, and alight on Mars to ask how our terrestrial experience can guide exploration for life beyond our planet. Along the way, Knoll brings us up-to-date on some of science's hottest questions, from the oldest fossils and claims of life beyond the Earth to the hypothesis of global glaciation and Knoll's own unifying concept of ''permissive ecology.'' In laying bare Earth's deepest biological roots, Life on a Young Planet helps us understand our own place in the universe--and our responsibility as stewards of a world four billion years in the making.In a new preface, Knoll describes how the field has broadened and deepened in the decade since the book's original publication.

    Although each discipline makes crucial contributions to contemporary environmental concerns, neither will fulfill its potential until it transforms itself by engaging the other. This book offers examples of how to relate environmental philosophy to science, public policy, and real world problems, and shows what is epistemologically distinctive about scientific work and how to respond to the cultural dynamics that are pulling these issues into the public sphere. Frodeman advocates humanizing the earth sciences and bringing philosophy into the field.

    Even the land is alive here, constantly changing and evolving as do all living things. Nothing here is 'finished.' Everything around us—the plants, the animals, the rocks, and the terrain itself—is in the process of becoming something else. And, of course, so are we. None of us around the campfire tonight are the same people we were yesterday, or will be tomorrow."—from the bookThe Broken Land surveys the geological phenomena of the magnificent Great Basin landscape of western Utah, Nevada, eastern California, and adjacent regions. Each chapter focuses on a locality or area that provides insight into the deep history of one of North America's most remote regions—one of its continental margins. It is the only book available covering the geology of the entire Great Basin. Written for anyone with a casual to serious interest in natural history, The Broken Land conveys Frank DeCourten's awe at the story written in the rock of the basin.
