by K. Lambeck, R. Sabadini and E. B08Chi Viscosity is one of the important material properties of the Earth, controlling tectonic and dynamic processes such as mantle convection, isostasy, and glacial rebound. Yet it remains a poorly resolved parameter and basic questions such as whether the planet's response to loading is linear or non-linear, or what are its depth and lateral variations remain uncertain. Part of the answer to such questions lies in laboratory observations of the rheology of terrestrial materials. But the extrapolation of such measurements from the laboratory environment to the geological environment is a hazardous and vexing undertaking, for neither the time scales nor the strain rates characterizing the geological processes can be reproduced in the laboratory. General rules for this extrapolation are that if deformation is observed in the laboratory at a particular temperature, deformation in geological environments will occur at a much reduced temperature, and that if at laboratory strain rates a particular deformation mechanism dominates over all others, the relative importance of possible mechanisms may be quite different at the geologically encountered strain rates. Hence experimental results are little more than guidelines as to how the Earth may respond to forces on long time scales.

This text, designed for the middle-level undergraduate geology major, incorporates both fundamentals and information on recent advances in our understanding of igneous, sedimentary, and metamorphic rocks. It provides an overview of the field of petrology and a solid foundation for more advanced studies. For each class of rocks -- igneous, sedimentary, and metamorhic -- the author describes textures, structures, mineralogy, chemistry, and classification as a background to discussing representative occurrences and petrogenesis (rock origins).

This volume explores 15,000 years of indigenous human history on the North American continent, drawing on the latest archaeological theories, time-honored methodologies, and rich datasets. From the Arctic south to the Mexican border and east to the Atlantic Ocean, all of the major cultural developments are covered in 53 chapters, with certain periods, places, and historical problems receiving special focus by the volume's authors. Questions like who first peopled the continent, what did it mean to have been a hunter-gatherer in the Great Basin versus the California coast, how significant were cultural exchanges between Native North Americans and Mesoamericans, and why do major historical changes seem to correspond to shifts in religion, politics, demography, and economy are brought into focus. The practice of archaeology itself is discussed as contributors wrestle with modern-day concerns with the implications of doing archaeology and its relevance for understanding ourselves today. In the end, the chapters in this book show us that the principal questions answered about human history through the archaeology of North America are central to any larger understanding of the relationships between people, cultural identities, landscapes, and the living of everyday life.
