- 論文の詳細を見る
When a molybdenite was dissolved and treated by the conventional chemical procedure, it was difficult to achieve the isotopic equilibrium between the 187Os radiogenically accumulated in the molybdenite and"common"Os added as a kind of internal standard, even after chemically complete decomposition. It is evident that this isotopic disequilibrium effect results in deterioration of Re-Os age for the molybdenite. A newly developed analytical technique employing a microwave digestion was found out to promote the isotopic equilibration of Os from two sources and to provide us with the ages concordant with those obtained by other geochronometers.
