The Common Rocks and Minerals of Missouri

A practical, illustrated field guide intended for residents and collectors that explains how to identify common rocks and minerals using a simple determinative key and nontechnical tests. It provides concise descriptions, diagnostic features, photographs, and explanations of formation processes and commercial uses for sedimentary, igneous, and metamorphic materials and common ores. Supplemental sections treat miscellaneous structures such as concretions, geodes, and fossils, discuss regional occurrences and economic considerations, and offer guidance on collecting and naming specimens without specialized equipment.
