Summary

X-ray diffraction procedures are discussed including specimen preparation, specimen carriers, diffractometer settings, and raw data treatments in order to obtain optimum results from small amounts (≤5 mg) of sediment trap samples. Low amounts of opal (12%) can be determined if the content of other amorphous materials such as organic matter is low. Relative quantitative mineralogy for lithogenic components of sediment trap samples is possible by using internal standards. An identification technique for small amounts of clay minerals is given which is based on applying different relative humidities to the specimens during scanning.
