1992 compilation of analytical data for rare‐earth elements, scandium, yttrium, zirconium and hafnium in twenty‐six GSJ reference samples

Abstract

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.

Tetrad effects and fine structures of REE abundance patterns of granitic and rhyolitic rocks: ICP-AES determinations of REE and Y in eight GSJ reference rocks.

“…The average for C.V. values of all REE and , Y is calculated to be (4 ± 1)%. The agreements of our results with the consensus val ues compiled by Itoh et al (1992) are generally good not only for JB-1 but also for JG-3, JG-la, JR-1 and JR-2. However, the compiled average values for Er in JG-1 and Ho, Er, and Tm in JG-2 are significantly lower than ours (Figs.…”

JR-3, a LIL-enriched GSJ rock reference sample.

“…Chon drite-normalized REE abundance pattern (Fig. 2) is similar to those of other GSJ rhyolite reference samples, JR-1 and JR-2 (Itoh et al, 1992), except for the absolute abundances. Above characteristics ensure the usefulness of JR-3 as an analytical standard of LIL in various kinds of instrumental analyses.…”

1994 compilation values for GSJ reference samples, "Igneous rock series".

“…Among those compila tions, however, concentrations of some elements were remained uncertain, being due to the insuf ficient accumulation of analytical data, especially for the samples recently issued. After the 1978 and 1989 compilations, concentration data for se lected several elements such as Ag, Au, Pd, Pt, Sc, Y, Zr, Hf, rare earth elements and major ele ments have fragmentarily been compiled (Terashima et al, , 1994Itoh et al, 1992). In this paper, we evaluate all the analytical data received by April 1994 for major, minor and trace elements, and a new set of 1994 recommended and preferable values is proposed for the 17 ref erence samples.…”
