内容記述 | Precise Sm and Nd isotopic measurements have been performed on whole rocks of four unique Yamato diogenites (Yamato-74013,-74037,-74097 and -74136). Although the observed ^<143>(Nd)/^<144>(Nd) ratios show some variations, ranging from 0.5126 to 0.5146,the data do not define an isochron. Rb-Sr measurements for mineral separates and whole rocks from the meteorites also do not yield a definite age information for these meteorites. The present results suggest that multiple young (possibly younger than 2.0 b. y.) metamorphic events may be responsible for the disturbance of the Rb-Sr and Sm-Nd systems of the meteorites. | |||||||
