Clays and Clay Minerals documents the proceedings of the 14th National Conference in Berkeley, California. This book focuses on the structure and quantitative analysis, surface reactivity, genesis, and synthesis of clays and clay minerals. Topics discussed include status of clay mineral structures; layer charge relations in clay minerals of micaceous soils and sediments; mechanical force fields in a clay mineral particle system; and kinetics of decomposition of cobalt coordination complexes on montmorillonite surfaces. The factors affecting the frequency distribution of clay minerals in soils; stability of brucite in the weathering zone of the new Idria serpentinite; and interrelationships of physical and chemical properties of kaolinites are also elaborated in this publication. This compilation is beneficial to students and researchers conducting work on clay mineral studies.
