| Abstract: | Data on seventeen Japanese geochemical reference samples are presented. Ten major and twenty-three trace element concentrations as well as the H2O + and H2O- were determined using x-ray fluorescence, colorimetry, coulometry and instrumental thermal neutron activation analysis. Error bars for the methods as well as information on some elements not previously published are presented. Good agreement was generally obtained with the recently published values of Ando.
Dix éléments majeurs et vingt éléments en traces ainsi que H2O+ et H2O- ont été dosés dans 17 échantillons de référence du Service Géologique du Japon. Les méthodes employées sont la spectrométrie de fluorescence-X, la coulométrie, la colorimétrie et l'activation neutronique thermique. En générale, un accord favorable est obtenu avec les valeurs publiées. |
