NICKEL IN TEKTITES BY ACTIVATION ANALYSIS
The nickel abundances of most of the major occurrences of tektites, as well as several meteorite impact glasses and obsidians, were determined using neutron activation analysis. Iron abundances were determined in the same specimens; and Ni/Fe abundance ratios were tabulated. These ratios, determined that for the first time on the Libyan Desert glass, the Ivory Coast tektites, and the bediasites, indicated all these specimens fall within the known range of this ratio for the other tektite occurrences. On the basis of this ratio, major differences were observed among specimens from the indochinite tektite occurrence. but no signfficant differences were observed among specimens from three separate philippinite sites. The differences in the Ni/Fe ratios for tektites and known meteorite impact glasses suggested different modes of formation. (auth)
