Scientific paper

Minimum diameters of lunar craters, capable of ejecting the liquid masses that could have formed the various tektite strewnfields, are calculated, using (1) estimates of the total masses of tektites in three strewnfields, (2) equations relating kinetic energy of impact to crater diameter, and (3) calculations of Orphal et al. (1980) of the amount of melt that could be ejected from impact craters. The moon is eliminated as a tektite source on the earth, because no lunar craters of the requisite sizes have been found that are young enough to correlate with the dates of formations of the strewnfields. The associations of the Ivory Coast tektites with the Bosumtwi crater, and the moldavites with the Rieskessel are real, and the tektites are of terrestrial origin.
