Abundances of eight rare-earth elements and barium have been determined by isotope dilution in an Ivory Coast tektite composite, an individual Ivory Coast tektite, two impactite glasses and three country-rocks from the Bosumtwi Crater area of Ghana. The rare-earth abundances are lower, in general, than those in previously analyzed tektites from different geographic localities. However, there is some overlap in the data and the differences may not be significant in view of the Limited rare-earth data on tektites. The rare-earth patterns of the meta-sedimentary country-rocks do not exactly match the patterns of the tektites, although there are general similarities. On the other hand, the Bosumtwi Crater impact glasses have rare-earth and barium abundances that are virtually identical to those in the tektites. This identity is viewed as supporting evidence that the Ivory Coast tektites were produced terrestrially by the impact that formed the Bosumtwi Crater.
