Description
Summary:Specific elemental and mineral composition of lacustrine and continental nodules differ substantially from silicate sedimentary rock, oceanic nodules, and crusts. The examination of this rock type requires study of the applicability of analytical methods to get accurate data on the elemental composition due to the lack of matrix-matched certified reference materials. In this study, multielement analysis of continental and lacustrine ferromanganese nodules was performed using various analytical methods. Samples were prepared as fused glasses and pressed pellets for wavelength-dispersive X-ray fluorescence, suspensions for total reflection X-ray fluorescence, and solutions after fusion for inductively coupled plasma mass spectrometry measurements. An intercomparison test was carried out to study the results using several analytical methods. [Display omitted] •Lacustrine and continental ferromanganese nodules were analyzed without matrix-matched certified reference materials.•Major elements can be quantified by WDXRF using different certified reference materials.•Minor and trace elements can be determined by TXRF using internal standard method and by ICP MS.•Particle size significantly affects TXRF results.
