1992 COMPILATION OF ANALYTICAL DATA FOR RARE-EARTH ELEMENTS, SCANDIUM, YTTRIUM, ZIRCONIUM AND HAFNIUM IN 26 GSJ REFERENCE SAMPLES

Analytical data for fourteen rare-earth elements, scandium, yttrium, zirconium and hafnium, received by May 1992, have been compiled on twenty-six GSJ (Geological Survey of Japan) reference samples. Seventeen of them are ''Igneous rock series' and nine are ''Sedimentary rock series''. The reported data including personal communication were evaluated under the consideration on analytical methods and geochemical evidences. No significant difference has been observed between the values obtained by the different analytical methods. Based on the selected available data, 1992 compilation values were tabulated.
