Rocks and Minerals. A guide to familiar minerals, gems, ores and rocks. Golden nature guides / Породы и минералы. Путеводитель по знакомым минералам, драгоценным камням, рудам и породам
Nothing is as important in the natural world as our own earth and the rocks beneath our feet. So it was inevitable that the Golden Nature Guides include an introduction to rocks and minerals. The task of selecting, describing, and illustrating minerals, rocks, and geologic structures has many inherent difficulties. We are grateful to our colleagues and to other experts who have helped. May we particularly thank members of the Geology Department of the University of Illinois: Drs. Chapman, Droste, Grim, Hagner, Henderson, Merrill, Wanless, and White, and Drs. Collinson, Swann, and Willman of the Illinois State Geological Survey for specimens and slides, and for information and encouragement. Some specimens came from University of Illinois Natural History Museum and departmental collections; some from Ward's Natural Science Establishment. The gem collections at the Chicago Museum of Natural History were invaluable. Fine Koda-chromes were provided by Scott Lewis. Maps came largely from information in the Minerals Yearbook of the Bureau of Mines, and from other maps and publications of the United States Geological Survey.
