This 1973 comprehensive catalogue examines the many presences and absences found within the characteristics of different types of quartz grain sand. The focal point of this work is the numerous micrographs, selected specifically for their ability to demonstrate the many variations in the surface textures of quartz grain sand.

Mahaney presents methods of using electron microscopy developed in the past 25 years, and discusses their values in the interpretation of sedimentary environments, the problems inherent in these methods, case studies and future possibilities for research.

Interpretation of Micromorphological Features of Soils and Regoliths, Second Edition, provides researchers and students with a tool for interpreting features observed in soil thin sections and through submicroscopic studies. After an introduction and general overview, micromorphological aspects of regoliths (e.g., saprolites, transported materials) are highlighted, followed by a systematic and coherent discussion of the micromorphological expression of various pedogenic processes. The book is written by an international team of experts in the field, using a uniform set of concepts and terminology, making it a valuable interdisciplinary reference work. The following topics are treated: freeze-thaw features, redoximorphic features, calcareous and gypsiferous formations, textural features, spodic and oxic horizons, volcanic materials, organic matter, surface horizons, laterites, surface crusts, salt minerals, biogenic and pedogenic siliceous materials, other authigenic silicates, phosphates, sulphidic and sulphuric materials, and features related to faunal activity. The last chapters address anthropogenic features,archaeological materials and palaeosoils. - Updates the first exhaustive publication on interpretation of micromorphological features, with some new chapters and with a larger number of additional references - Covers related topics, making micromorphology more attractive and accessible for geomorphologists, archaeologists and quaternary geologists Includes thematic treatment of a range of soil micromorphology fields and broadens its applications - Features input from a multi-disciplinary team, ensuring thorough coverage of topics related to soil science, archaeology and geomorphology

The thirty papers in this 1986 volume review the scientific knowledge of the nature of flint and chert at this time. These papers were presented at a 1983 interdisciplinary and international conference on flint and other cherts. Each contribution has been meticulously assessed and edited prior to publication. This collection is principally concerned with the geology and geochemistry of flint in European chert. Topics include the origin of flint; scanning electron microscopy of surface textures; and the behaviour of flint under periglacial conditions. There is a companion volume, edited by G. de G. Sieveking and M. B. Hart, on the archaeological uses of flint.
