Four new geochemical reference materials, soils JSO-1 and JSO-2, and marine sediments JMS-1 and JMS-2, have been prepared by the Geological Survey of Japan (GSJ) for collaborative studies on their chemical composition. In the case of JSO-2, thirty one compounds were artificially added to a natural soil, mostly as oxides, in order to provide a soil reference material that contains known chemical forms of minor and trace elements. Homogeneity test results and provisional values of thirty seven major, minor and trace elements are presented to support future collaborative analyses. The homogeneity tests showed that all elements studied can be considered to be homogeneously distributed. A description of the geological and mineralogical characteristics of the materials is also given.
Quatre materiaux geochimiques de reference, les sols JSO-1 et JSO-2 et les sediments marins JMS-1 et JMS-2 ont ete prepares par le “Geological Survey of Japan” (GSJ) en vue de leur caracterisation chimique en collaboration entre laboratoires. Dans le cas de JSO-2, trente trois composants ont ete ajoutes artificiellement a un sol naturel, principalement sous forme oxyde, afin de fournir un materiau de reference de sol qui contienne des elements mineurs et en trace sous des formes chimiques connues. Les resultats des tests d'homogeneite et des valeurs indicatives pour trente sept elements majeurs, mineurs et en trace sont presentes comme point de depart a toute analyse en collaboration. Les tests d'homogeneite ont montre que tous les elements etudies peuvent etre consideres comme etant distribues de facon homogene. Une description des caracteristiques petrologiques et mineralogiques des materiaux est aussi donnee.
