内容記述 |
Carbon was extracted from 1g samples of ten Antarctic chondrites, using stepwise heating. The evolved CO_2 was collected at 1000℃, melt and remelt. The ^<14>C concentrations were measured at the Isotrace AMS facility and were compared with the zero-age ^<14>C concentration of the Bruderheim (L6) chondrite. The Allan Hills meteorite ALH-77231 (L6) yielded a terrestrial age, not corrected for in situ production, of 30ka. The uncorrected terrestrial ages of the 9 Yamato meteorites Y-74014 (H6), Y-74097 (Dio), Y-74191 (L3), Y-75271 (L5), Y-790448 (LL3), Y-791500 (H3), Y-791630 (L4), Y-791717 (C3) and Y-74647 (H5) showed a wide range from 500a to 30ka. |
