A procedure for the non‐destructive x‐ray fluorescence (XRF) spectrometric determination of major and some minor elements in soils, marine sediments and friable deposits is proposed. It does not require any preliminary treatment of the sample except for its drying at 105°C. The matrix correction procedure used is based on α‐ coefficients which are simulated for maximum possible variations of interfering element concentrations in the matrix and are calculated on the assumption that the sample is homogeneous. The achieved agreement between the XRF results and the certified values is satisfactory. The paper discusses why the above material cannot be homogenized by fusion and the effect of this on the XRF results.
