Practical, concise, and easy to use, Simon & Schuster's Guide to Rocks and Minerals contains everything that the rock and mineral enthusiast needs to know. This field guide is divided into two large sections -- one devoted to minerals and one to rocks, each prefaced by a comprehensive introduction that discusses formation, chemistry, and more. All 377 entries, beautifully illustrated with color photographs and helpful visual symbols, provide descriptions and practical information about appearance, classification, rarity, crystal formation, mode of occurrence, gravity of mineral, rock chemistry, modal classification fields, formational environments, grain sizes of rocks, and much more.
Whether you are a serious collector or an information-seeking amateur, this incomparably beautiful, authoritative guide will prove an invaluable reference.
Map identifies locations of: gold and silver, agate, beryl, corundum, epodote, feldspar, garnet, geodes, jasper, nodules, opal, opalized wood, petrified wood, quartz, rhodonite, thunder eggs, topaz, tourmaline, and zeolite.
This packet contains 4 17 1/2 X 23 inch maps printed on both sides. The maps divide the state into four sections and show the location of 119 gems in addition to gold and silver. The maps featured were chosen due to their clarity in spite. This package is a must for both the serious or the part time rock hound.

Montana's geologic history includes a long succession of disturbances that changed the rocks, then changed many of them again. Unraveling these events reveals a geologically quiet continent that got scrambled in a long and grinding collision with the Pacific crustal plate. Through detailed geologic maps and lively text, Roadside Geology of Montana deciphers the complicated rock record and uncovers each layer of Big Sky Country.
