• The identification of rock-forming and clay minerals contained in the reference material of "Pond Sediment" (Reference Material NIES No. 2 from the National Institute for Environmental Studies, Japan) has been made with X-ray diffraction method. It was found that the sediment contained α-quartz and feldspars as the principal components along with small quantity of pyroxenes, amphiboles, and some clay minerals. The sediment sample was treated chemically for extraction, and also separated with density and with grain sizes. Elemental compositions of such extracted or separated fractions of the sediment were determined by inductively coupled argon plasma emission and atomic absorption spectrometry. The identified minerals and the elemental distributions in the separated fractions helped to characterize the pond sediment.
