          <datacite:description descriptionType="Abstract">日本標準試料JG－1a，JG－2，JR－1，JA－1，JB－1a，JB－2，JB－3，JGb－1，JP－1，JF－1を使い，螢光Ⅹ線分析装置により，主要元素SiO_2，TiO_2，A1_20_3，Fe2_0_3，MnO，MgO，CaO，Na_20，K_20，P_20_5の分析を行なった。これらの分析結果はJP－1のFe_20_3を除いて1989年にすでに報告されている日本標準岩石試料の分析値とよく一致している。また試料と4ホウ酸リチウムを1：9で混合し，ビード・サンプラを用い1200℃で溶解したガラス円板をつくり分析したが，五回線り返し溶解しても分析値に影響を与える程アルカリの蒸発は認められなかった。</datacite:description>
          <datacite:description descriptionType="Abstract">Si0_2, TiO_2, A1_20_3,, Fe_20_3, MnO, MgO, CaO, Na_20, K_20 and P_20_5, contents in the ten rock reference samples of "Igneous rock series" issued by the Geological Survey of Japan have been determined by X-ray fluorescence method. The ten rock reference samples are as follows : granites JG-1a and JG-2, rhyolite JR-1, andesite JA-1, basalts JB-1a, JB-2 and JB-3, gabbro JGb-1, pelidotite JP-1 and feldspar JF-1. The analytical data were in good agreement with the 1989 values reported already. Alkali content in the glass disk with rock powder against flux (Li_2B_40_7,) of 1 : 9 is constant after melting at 1200℃ five times.</datacite:description>
