Origin and Mineralogy of Clays
Origin and Mineralogy of Clays, the first of two volumes, lays the groundwork for a thorough study of clays in the environment. The second volume will deal with environmental interaction. Going from soils to sediments to diagenesis and hydrothermal alteration, the book covers the whole spectrum of clays. The chapters on surface environments are of great relevance in regard to environmental problems in soils, rivers and lake-ocean situations, showing the greatest interaction between living species and the chemicals in their habitat. The book is of interest to scientists and students working on environmental issues.
Clays in the Critical Zone
Clay and clay minerals on Earth's surface and in watershed areas.
The Origin of Clay Minerals in Soils and Weathered Rocks
Of huge relevance in a number of fields, this is a survey of the different processes of soil clay mineral formation and the consequences of these processes concerning the soil ecosystem, especially plant and mineral. Two independent systems form soil materials. The first is the interaction of rocks and water, unstable minerals adjusting to surface conditions. The second is the interaction of the biosphere with clays in the upper parts of alteration profiles.
Illite
This monograph examines the mineralogy of illite, the most common clay mineral, as a unifying theme for understanding problems of the surface environment and environmental change. The volume begins with a careful analysis of the structure and transformation of illite. Using illite as the frame, the authors describe problems in soil chemistry, clay stability and clay kinetics in sedimentary rocks.
Introduction to Clay Minerals
Introduction to Clay Minerals is designed to give a detailed, concise and clear introduction to clay mineralogy. Using the information presented here, one should be able to understand clays and their mineralogy, their uses and importance in modern life.
Soil Clays
As the human population grows from seven billion toward an inevitable nine or 10 billion, the demands on the limited supply of soils will grow and intensify. Soils are essential for the sustenance of almost all plants and animals, including humans, but soils are virtually infinitely variable. Clays are the most reactive and interactive inorganic compounds in soils. Clays in soils often differ from pure clay minerals of geological origin. They provide a template for most of the reactive organic matter in soils. They directly affect plant nutrients, soil temperature and pH, aggregate sizes and strength, porosity and water-holding capacities. This book aims to help improve predictions of import...
Geochemistry at the Earth’s Surface
Geochemistry at the surface of the earth is dominated by two somewhat antagonistic forces: chemical reactions which attempt to attain a steady state (equilibrium) and geological movement of materials in time and space which changes the parameters that control chemical equilibrium. Another aspect that is extremely important to earth surface geochemistry is the effect of plants on the chemical and physical stability of materials (soils). Plant systems in fact work against the normal chemical changes (loss of silica, potassium, etc.) and the normal physical changes (stabilizing fine grained materials (clays) in the surface zones to avoid erosion). Biological effects are clearly seen in redox effects in the various parts of the earth surface movement cycle; soil formation, stream transport, sedimentation. This book attempts to outline these different parameters and their interactions as they affect earth surface geochemistry in order to give a better understanding of movement and accumulation of elements at the surface of the earth.
Occupational Therapy and Mental Health
This book is a comprehensive textbook for occupational therapy students and occupational therapists working in the field of mental health. It presents different theories and approaches, outlines the occupational therapy process, discusses the context of practice and describes a wide range of techniques used by occupational therapists. These include physical activity, cognitive approaches, group work, creative activities, play and life skills. The book covers all areas of practice in the field, including mental health promotion, acute psychiatry, community work, severe and enduring mental illness, working with older people, child and adolescent mental health, forensic occupational therapy, su...
Archaeological Ceramic Materials
Archaeological Ceramic Materials is an introduction to the origin and the analysis of the most abundant material found in archaeologyceramics. In this volume, the authors explain the origin of the components of ceramic materials, the choice of these materials by potters as a function of use and physical properties, the effects of firing on ceramic materials, and the means used to analyze the ceramics in a post-use context.
