A scientific introduction looks at the origins of these materials and their impact on the landscape, with examples of striking natural formations and explanatory diagrams. The amateur geologist is shown how to identify specimens by their appearance, texture, hardness, and density, as well as how to extract samples safely, how to clean and store rocks and minerals, and build and present their own collection.
