Clay Mineralogy: Spectroscopic and Chemical Determinative Methods

A knowledge of clay is important in many spheres of scientific endeav­ our, particularly in natural sciences such as geology, mineralogy and soil science, but also in more applied areas like environmental and mater­ ials science. Over the last two decades research into clay mineralogy has been strongly influenced by the development and application of a num­ ber of spectroscopic techniques which are now able to yield information about clay materials at a level of detail that previously would have seemed inconceivable. This information relates not only to the precise characterization of the individual clay components themselves, but also to the ways in which these components interact with a whole range of absorbate molecules. At present, however, the fruits of this research are to be found principally in a somewhat widely dispersed form in the scientific journals, and it was thus considered to be an appropriate time to bring together a compilation of these spectroscopic techniques in a way which would make them more accessible to the non-specialist. This is the primary aim of this book. The authors of the various chapters first describe the principles and instrumentation of the individual spectro­ scopic techniques, assuming a minimum of prior knowledge, and then go on to show how these methods have been usefully applied to clay mineralogy in its broadest context.
