| Abstract: | Major and trace elements have been determined by wavelength dispersive X-ray fluorescence and by inductively coupled plasma optical emission spectroscopy (ICP-OES), in the Geological Survey of Japan Igneous rock series, using a routine sample preparation technique including lithium borate fusion. Samples were analysed for 10 majors elements and the following trace elements: Ba, Co, Cr, Ga, Nb, Sc, Sr, V, Y, Zn and Zr. The rare-earth elements were determined only by ICP-OES following separation by ion exchange. In most cases, results compared well with published values. |
