Abstract Zinc and copper concentrations have been determined by spectrophotometric and emission spectrographic techniques in a number of tektites (i.e. australites, javaites, phillipinites, indochinites, bediasites and moldavites). The data indicate a considerable loss of zinc and, possibly, copper from the tektite parent material by selective volatilization during the fusion process which formed the tektites. Furthermore, the observed positive correlation between mass and specific gravity in both the australites and bediasites indicates that the major element content of tektites has also been significantly altered by selective volatilization. This work suggests that acid igneous rocks are suitable parent materials for the formation of tektites.
