National Audubon Society® guides feature full-color glossy photographs that arrange specimens by similar appearance rather than by strict family grouping. This system is particularly useful when identifying rocks and minerals in the field, where several pieces may appear similar.The Field Guide to Rocks and Minerals introduces the common rocks and minerals found in North America, with 794 photographs that depict all the important rocks, gems, and minerals in their many variations of color and crystal form. Each entry describes the natural environments in which each specimen occurs, and provides information on field marks, similar rocks and minerals, environment, areas of occurrence, and derivation of names. The book also features a useful guide to mineral collecting and a list of rock-forming minerals.
