Neutron activation analysis was employed to determine the abundances of I, Te and U in seven bronzite and hypersthene chondrites, three enstatite chondrites and two carbonaceous chondrites. On the basis of twenty-three analyses, the mean abundances in p.p.m. for the three groups were: iodine, 0.040, 0.17 and 0.27; tellurium, 0.51, 2.1 and 1.9; uranium, 0.013, 0.011 and 0.017. In meteoritic iron (four analyses), these abundances covered a wider range, i.e. 11-320, 17-90 and <0.15- <0.6 p.p.b., whereas five analyses of troilite gave 24-3600, 1200-5000 and 3.5-17 p.p.b. These data indicate that Te, and to a lesser extent I, are chalcophile in iron meteorites. In chondrites, I and Te are strongly correlated, and appear to reside (in part) in the same phase, tentatively identified as CaS or MgS. Four of the meteorites in the present study had been previously analysed by . His values are found to be uniformly too high by factors of 5-30. It seems likely that most of the data in his fundamental study of the geochemistry of iodine are systematically too high by comparable factors.
