Carbon-14 terrestrial ages of six Antarctic meteorites have been measured by accelerator mass spectrometry. These six and three additional Antarctic meteorites were also measured by small counters. The results are in general agreement, with some differences that are related to the calibration samples used. Yamato 75102 was found to be the youngest meteorite yet measured from the Antarctic collections, 3¿103 yrs. The ages for the Yamato meteorites are younger than those from sites in the Allan Hills region. Accelerator data on Allan Hills (ALHA) samples, 77232 and 80101, show limit ages >48¿103 yrs. Counter measurements on ALHA 77208, 77269, and 79025 give limit ages >38¿103, >34¿103, and >38¿103 yrs, respectively. Accelerator measurements on MBRA 76001, a sample previously measured by counting, gives a finite age of 39¿103 yrs. The younger ages of meteorites of the Yamato region are suggested to by the result of the larger recovery area and the more ''porous'' barrier at the Yamato Mountains.
