This book concerns the nature, origin, evolution and signifi cance 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. <...>
Earth and mind: These are the substance and essence of our work as geoscientists. Earth is the focus of our work—understanding its systems and sensitivities. Mind is the most important asset we bring to this work. Geoscientists learn a body of knowledge that frames their thinking, a battery of methods that they can use to address a problem, and a sophisticated set of skills for collecting and analyzing data. But perhaps most important, geoscientists have a way of thinking about Earth that grows from a combination of their training, their scientific work, and their world experiences. While each individual is unique, geoscientists share a common core of interests, approaches, skills and knowledge that constitute geoscience expertise. This volume explores the nature of that expertise. <...>
The geological (endogenic and exogenic) processes operating in interior and exterior domains of earth are bringing dynamic changes in the lithospheric and geomorphic terrains of this planet since its origin. The interplay of magmatic, tectonometamorphic and metallogenic processes is continuously evolving new continental and oceanic plates (blocks) enriched with magmatic plume and economic minerals. The diverging and converging margins of these blocks were stressed and formed orogenic mobile belts and mountains.
New Theory of the Earth is an interdisciplinary advanced textbook on all aspects of the interior of the Earth and its origin, composition, and evolution: geophysics, geochemistry, dynamics, convection, mineralogy, volcanism, energetics and thermal history. This is the only book on the whole landscape of deep Earth processes that ties together all the strands of the subdisciplines.
This book is a complete update of Anderson’s Theory of the Earth (1989). It includes dozens of new figures and tables. A novel referencing system using Googlets is introduced that allows immediate access to supplementary material via the internet. There are new sections on tomography, self-organization, and new approaches to plate tectonics. The paradigm/paradox approach to developing new theories is developed, and controversies and contradictions have been brought more center-stage. As with the Theory of the Earth, this new edition will prove to be a stimulating textbook for advanced courses in geophysics, geochemistry, and planetary science, and a supplementary textbook on a wide range of other advanced Earth science courses. It will also be an essential reference and resource for all researchers in the solid Earth sciences.
We wrote Exploring Geology so that students could learn from the book on their own, freeing up instructors to teach the class in any way they want. I (Steve Reynolds) first identified the need for this book while I was a National Association of Geoscience Teachers’ (NAGT) distinguished speaker.

Because scientific inquires and discoveries are and have always been affected by history, a retrospective view of the historical development of the earth sciences seems a good place to begin our discussion of the planet Earth. While this historical survey is necessarily brief—this is, after all, a Little Book—it will establish the foundations of modern earth science and introduce important thinkers and scholarly developments. <...>
Why do earthquakes, volcanoes, floods, and landslides happen? What causes mountains to rise? How do beautiful landscapes develop? How have climate and life changed through time? When did the Earth form, and by what process? Where do we dig to find valuable metals, and where do we drill to find oil? Does sea level change? Do continents move? The study of geology addresses these important questions and many more. But from the birth of the discipline, in the late 18th century, until the mid-20th century, geologists considered each question largely in isolation, without pondering its relation to the others.
