All aspects are covered: mineralogy, major- and trace-element compositions, and isotope (radiogenic and stable) geochemistry. Geochemistry and mineralogy of soils eaten by humans. Between these bands are coarser-grained material (1-2 mm grain size) with similar mineralogy, but a higher modal plagioclase content. Among the chapters are such aspects as precipitation mechanisms, classification, chemistry, mineralogy, stable isotopes, associated organisms, and depositional processes. There are also appendices containing determinative tables for handspecimen identification, determinative tables for optical mineralogy and a glossary. Evaporites are classified as primary, secondary and tertiary, 'secondary' corresponding to diagenetic (including sabkha textures and mineralogies) and 'tertiary' to evaporites in the exhumation stage. Their concentrations are only partly coupled to the clay mineralogy. The chapter presents case studies of different types of alteration, and discusses detailed mineralogy of selected clay mineral types. Based on the martian mineralogy and geochemistry a suite of possible reactants and products was created. The lamprophyres may be classified as spessartites and minettes on the base of their mineralogy. While the cur rent volume is primarily aimed at materials sciences, the methods are equally applicable to problems in mineralogy and petrology. Major and trace elements showed a diversity of composition, controlled by the mineralogy. These examples are from corpora and from sources on the web.
