A specialized system of terms and concepts must be used to accurately and effectively distinguish and name the microscopic features of soils and regoliths. With a comprehensive, consistent terminology at their disposal, researchers may compare, store and discuss new data easily and with less risk of error. The second edition of Guidelines for Analysis and Description of Soil and Regolith Thin Sections has been assembled to address this need, offering a practical system of analysis and description to those working with soil and regolith materials.
This essential resource includes:
* An introduction to micromorphology and its practice
* Guidelines for the study of thin sections
* Sections covering the various microscopic features of soils and regoliths
* Illustrative graphics and colour micrographs
* Suggested description schemes and data presentation tips
By providing an economical, navigable system for the study and documentation of soils and regoliths, Guidelines for Analysis and Description of Soil and Regolith Thin Sections, second edition, offers invaluable guidance for soil scientists, geologists, ecologists, archaeologists and all those concerned with micromorphology.
