Crystal Structure Data of Inorganic Compounds. Part b3: Key Elements S, Se, Te

part introduces the techniques and includes chapters on data storage and retrieval, control procedures in geochemical analysis, univariate analysis, sampling methodology, mapping, and multivariate analysis (certainly not the most logical order). These chapters are easy to understand and contain a large number of worked examples and useful figures. Of particular use are the graphical aids for some statistical tests for up to 1000 samples. Portrayal of results is extremely important in mineral exploration and so the large section on geochemical mapping techniques is a most welcome addition. The second part attempts to survey the statistical and cartographic techniques which are used in geochemical exploration in various parts of the world. This is of undoubted value for illustrating the actual usage of these techniques but unfortunately does, in places, appear more as a catalogue of references. Considering the cost of the book some of these sections are an inefficient usage of space. This book is highly recommended for any geochemist who needs an introduction to the interpretation and portrayal of analytical data. One can only wait and see if geochemists increasingly adopt such statistical techniques in the interpretation of their results. Certainly the exorbitant price will deter most individual purchasers and will not help in disseminating the wealth of useful information contained within the book.
