Minerals and rocks form the foundation of geologic studies. Excellent textbooks currently exist in mineralogy, igneous petrology, sedimentary petrology and metamorphic petrology. It is not our intention to compete with these textbooks. However, many universities have compressed separate mineralogy and petrology courses into a one- or two-semester Earth Materials course. Presently, no textbook adequately addresses the needs of an Earth Materials course. We have developed a textbook that encompasses the study of minerals, rocks as well as soil and water. This Earth Materials textbook is geared towards a one- or two-semester Earth Materials course, a combined mineralogy and petrology course, and can also be used by environmental scientists, engineering geologists, planners and laypersons interested in learning about minerals, rocks, soil and water in a comprehensive framework. We have attempted to create a readable, well illustrated textbook that is comprehensible and that weaves different disciplines into one cohesive fabric.Key features of this book include:Equal coverage of mineralogy, sedimentary petrology, igneous petrology and metamorphic petrologyCopious field examples and regional relationships with graphics that illustrate the concepts discussedNumerous case studies to show the uses of earth materials as resources and their fundamental role in our lives and the global economy, and their relation to natural and human-induced hazardsThe integration of earth materials into a cohesive process-based earth systems framework2 color throughout with a 64 pages 4 color sectionA companion website is available for this title at www.wiley.com/go/hefferan/earthmaterials.
