Extraction methods of Rb, Sr, Sm and Nd from rocks and minerals are described. Sr isotope ratio of standard sample NBS987 was repeatedly measured for a long terrn, using a mass spectrometer MAT262 at the Department of Geoscience, Shimane University. The isotope ratio is in a restricted range from 0.710260±0.000009 (2σ) to 0.710285±0.000009 (2σ). Sr isotope ratio was measured for the same six samples at the Department of Geosience, Shimane University and the Institute for Study of the Earth's Interior，Okayama University. Each sample gave quite similar isotope ratio13;
