DETERMINATION OF TWELVE TRACE ELEMENTS IN TWENTY-SEVEN AND TEN MAJOR ELEMENTS IN TWENTY-THREE GEOCHEMICAL REFERENCE SAMPLES BY X-RAY FLUORESCENCE SPECTROMETRY

This study reports the results of twelve trace elements in twenty-seven International geochemical reference samples (IGRS) (15 from Japan, 7 from South Africa, 4 from France and 1 from U.S.A.). Similarly, ten major elements were also determined in twenty-three GRS (15 from Japan, 5 from South Africa, 2 from France and 1 from U.S.A.). Whenever possible, the results are compared with literature values for these GRS.
