| 초록 | : Isotope Dilution Mass Spectrometry (IDMS) is one of the analytical method which uses enriched isotope spikes and analyzes the abundance of element by comparison of the spectrum between spiked mass and non-spike mass. Especially, the Thermal Ion Mass Spectrometry with isotope dilution technique (in general ID-TIMS) is the most accurate method of the chemical analysis, which enables us to obtain the data better than 1% in accuracy and precision. In IDMS , enriched isotope spike is one of the most important factor in order to obtain the best data. For rare earth elements, in general, a mixture of 138La, 142Ce, 145Nd, 149Sm, 151Eu, 157Gd, 163Dy, 167Er, 171Yb, and 176Lu is used as composite spike. IDMS is very useful in geochronology and REE geochemistry. Especially, it is very effective in studying the "tetrad effect" of rare earth elements in natural samples. As a result of repeated experiment in order to estimate REE abundance for some gneiss sample, we found that there are some difference in their REE abundance and, nevertheless, existed some regularities in chondrite-normalized REE pattern. Therefore, our results confirm that rare earth elements are very usefiul tool for solving various kinds of geochemical problems in earth environment |
