Abstract

The procedure used for fractionation of soils, rocks, and sedimentary materials involves separation of the clay (less than 2 microns) and silt (2 to 62 microns) by centrifugation. Randomly oriented powders and oriented aggregates of these materials are examined using X-ray diffraction as the principal method of analysis.
