CLAY MINERAL SEPARATION FOR XRAY DIFFRACTION ANALYSIS 1. PURPOSE The purpose of this procedure is to describe separation of clay minerals from bulk rock samples and preparation of oriented sample mounts of clay miherals for analysis by xray diffraction. 2. SCOPE The procedure applies to separation and xray diffraction ...
requirements in the analysis of powder samples by Xray diffraction (XRD). This statement is especially true for soils and clays that contain finely divided colloids, which are poor reflectors of xrays, as well as other types of materials such as iron oxide coatings and organic materials that make characterization by XRD more difficult.

Approximately 2/3th of the participants also investigated oriented slides with Xray diffraction for clay mineral identification. The graph below very clearly illustrates that the use of oriented clay slides very strongly affects the total bias, and thus the final position in the ranking. Larger Image

Despite the availability of other techniques, Xray diffraction remains a basic tool for studying minerals and we hope that this monograph will continue to serve, as did the previous editions, both those concerned with the more academic aspects of clay mineralogy and also those, such as geologists, civil engineers and soil scientists, for whom ...
In this article, several quantification methods for clay minerals sourced from Xray diffraction (XRD) analysis, mainly recommending the reference intensity ratio (RIR), mineral intensity factor (MIF), Rietveld, and full pattern summation methods are reviewed. Principles and applications of these methods are focused upon in addition to related ...
