Iodine and tellurium abundances in chondritic meteorites were determined by neutron-activation analysis. For bronzite and hypersthene chondrites (6 analyses), iodine abundances from 37 to 104 ppb were found; for enstatite and carbonaceous chondrites (9 analyses), the range was from 127 te 560 ppb. The tellurium abundances ranged from 0.42 to 0.73 ppm and 1.23 to 3.4 ppm, respectively. I/sup 129/Xe/sup 129/ decay intervals, measured from the cessation of nucleosynthesis, were calculated for the meteorites Richardton (119/sup +9// sub -6/m.y.) and Indarch (97/sup +17//sub -10/ >im.y.), using the continuous nucleosynthesis model. The significance of these results is discussed. (auth)
