CHAPTER 7 - Rock and Mineral Analysis

Abstract

This indispensable laboratory reference provides the practicing analyst with an up-to-date treatment of the problems associated with the analysis of geological materials. Rock and Mineral Analysis, 2nd Ed. serves as an authoritative guide to the determination of major, minor, and trace elements in rock and minerals, and covers all the requesite steps, from selection of the sample and choice of elements to be determined to facilities needed, preparation of the sample, methods for the determination of individual constituens, and reporting of the results of the analysis. Emphasis in this fully revised and update edition is on the instrumental analysis of rocks and minerals. The new edition thus complements the first edition in which emphasis was largely on the classical wet methods. Here, set forth, on an analyte-by-analyte basis are detailed methods for the determination of: 1) 12 constituents by specific techniques, such as moisture, carbon dioxide and flourine; 2) 30 major, minor, and trace constituents by atomic absorption spectroscopy (AAS); 3) 40 major, minor, and trace constituents by X-ray fluorescence spectroscopy (XRF). The analytes selected are the ones most commonly requested in the analysis of materials. Special attention has been given to new advances in sampling theory, and the previous discussions of standard reference materials and of sample decomposition techniques have been significantly expended.
