George Stoops, a world expert on thin section analysis, presents the most up-to-date system of analysis and description of soil and regolith materials as seen in thin sections. Scientists and students from archaeology to pedology will appreciate the introduction of micromorphology, the thorough treatment of all features that may be encountered, and especially the convenient system to key out those features. Bulleted lists and set-off definitions make this book work well in class and as a lab reference.
