A simple technique for the determination of Fe and Mn in concretions and soils was developed using X-ray fluorescence. A 25 mg sample was suspended in a 1% glue-methyl alcohol solution and transferred to a 4.25-cm circle of filter paper. The filter paper containing a thin layer of uniformly distributed sample was placed in an X-ray emission spectrograph for analysis, and highly reproducible and accurate results were obtained. Precision was achieved over a wide range of Fe and Mn oxide contents.
