In this visionary book, noted planetary scientist John S. Lewis explains how we can mine these precious metals from the asteroids, comets, and planets in our own solar system for use in space construction projects. And this is just one of the possibilities. Join John S. Lewis as he contemplates milking the moons of Mars for water and hollowing out asteroids for space-bound homesteaders—all while demonstrating the economic and technical feasibility of plans that were once considered pure fiction.

    Clear, accessible format, charts, diagrams, field tips, practical pointers, and historical profiles.

    Nonetheless, it is unique in that it truly portrays dinosaurs from a specialist viewpoint. It is the only comprehensive text that takes an explicitly phylogenetic approach to this group. The geological context of dinosaurs is also stressed, and dinosaurs are presented in the context of contemporary plate tectonic and climatic settings. The authors also cover topics of interest in dinosaur palaeobiology, 'hot-blooded' dinosaurs, aspects of dinosaur functional morphology and the relationships of dinosaurs to birds. All of the discussion is couched in lively and accessible language, and the book is lavishly illustrated by specially commissioned line drawings and colour plates that show dinosaurs in a variety of natural settings.

    It includes accounts of the scholars and theologians who have endorsed or rejected the flood story.

    The New Penguin Dictionary of Geology contains over 7,500 fully updated definitions, making it the most extensive dictionary of the Earth sciences ever produced. It includes a full bibliography of up-to-date works covering all areas of geology. Authoritative and accessible, this new edition will prove invaluable to researcher, student and amateur geologist.

    A place for sensing thewonder of the world could be any place, for all have shared a common journey that has made the earth our home. To listen from any spot is to hear the quiet echoes of a billion cycles around the sun. In A Place on the Glacial Till, Thomas Fairchild Sherman writes about the history of the life and land around his long-time home in Oberlin, Ohio, offering a quiet message that speaks to us wherever we are: that all time and nature abide within the rocks and soil, with connections, beauty, andmeaning as deep as history and as broad as human understanding. The area surrounding Oberlin has a rich and varied past, and Sherman weaves together old and new findings from geology, archeology, and ecology to remind us of its elemental roots. Over the millennia this region of north central Ohiohas been a barren, glacier-covered land mass; a sea bed teeming with marine life; the homeland of the Adena, Hopewell, and Erie peoples; a part of the Connecticut Western Reserve; and the home of a small, distinguished college dedicated to music and the arts and sciences. The land today holds allthe wildernesses of its past, and all the dreams and aspirations of those who have lived upon it. Reminiscent of the meditative prose of Annie Dillard and the environmental writing of John McPhee, A Place on the Glacial Till recalls a multitude of studies of time and nature and joins them in a new appreciation of the land and its meaning for our lives.

    Various sedimentary rock-types, textures and all the basic field techniques required are clearly described. Thoroughly revised to incorporate up-to-date information, this 3rd edition will be of use to all students and professionals with a geological background. Features include: New sections on safety in the field, the use of GPS in sedimentary studies, core description, fossils as depth indicators and facies models. Improved illustrations and a new updated layout.

    

    This book offers the engineer and geologist a manual to accomplish these goals, providing much-needed calculations and formulas on fluid flow, rock properties, and many other topics that are encountered every day. New updated material covers topics that have emerged in the petrochemical industry since 1997.

    

    This thought-provoking study presents a single straightforward structure which unites the latest scientific views on the history of the universe, the solar system, the planet, life and humankind. The focus on the formation, differentiation and transformation of configurations, regimes, and on the ever-changing reactions and interactions between them produces a simple, dynamic and reality-congruent structure with which to view the whole of history. It contributes to a better understanding of some long-standing academic controversies such as the root causes behind the origins of humankind, the rise of agriculture and the emergence of early states.

    Physical properties are a key for combined interpretation techniques. The study of rock physics provides an interdisciplinary treatment of physical properties, whether related to geophysical, geotechnical, hydrological or geological methodology.The book is a comprehensive and concise systematic presentation of the physical properties of rocks. It is focussed on the problems of applied geophysics with respect to exploration and the expanding field of applications in engineering and mining geophysics, geotechnics, hydrology and environmental problems, and the properties under the conditions of the upper earth crust. This volume contains theoretical and experimental results relating to the main geophysical properties - density, magnetic properties, natural radioactivity, elastic and anelastic properties, electrical and thermal. It also presents the correlation between the individual properties as a basis of modern interpretation methods, including relationships between geophysical and geotechnical properties.
