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 petrology Copious field examples and regional relationships with graphics that illustrate the concepts discussed Numerous 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 hazards The integration of earth materials into a cohesive process-based earth systems framework 2 color throughout with a 64 pages 4 color section

Chapter One
Earth materials and the geosphere
1.1 EARTH MATERIALS
This book concerns the nature, origin, evolution and significance of Earth materials. Earth is composed of a variety of naturally occurring and synthetic materials whose composition can be expressed in many ways. Solid Earth materials are described by their chemical, mineral and rock composition. Atoms combine to form minerals and minerals combine to form rocks. Discussion of the relationships between atoms, minerals and rocks is fundamental to an understanding of Earth materials and their behavior.
The term mineral is used in a number of ways. For example, elements on your typical breakfast cereal box are listed as minerals. Oil and gas are considered mineral resources. All these are loose interpretations of the term mineral. In the narrowest sense, minerals are defined by the following five properties:
1 Minerals are solid, so they do not include liquids and gases. Minerals are solid because all the atoms in them are held together in fixed positions by forces called chemical bonds (Chapter 2).
2 Minerals are naturally occurring. This definition excludes synthetic solids produced through technology. Many solid Earth materials are produced by both natural and synthetic processes. Natural and synthetic diamonds are a good example. Another example is the solid materials synthesized in high temperature and high pressure laboratory experiments that are thought to be analogous to real minerals that occur only in the deep interior of Earth.
3 Minerals usually form by inorganic processes.
