有关玻璃陨石分布的问题进行了研究，考虑到澳大利亚的散落场，象牙海岸散落场，Moldavite散落场，北美散落场，利比亚沙漠玻璃，Aouelloul陨石坑玻璃，和amerikanites。注意的是玻璃陨石的形状，玻璃陨石的内部结构，玻璃陨石玻璃的物理性质，玻璃陨石的化学成分，同位素，裂变轨道，宇宙射线轨道，和赞成和反对玻璃陨石的陆地起源的论点。得出的结论是，玻璃陨石不可能是陆地的起源。它们很可能是地质学上较新时期的火山喷发物，来自一个或多个月球火山。
Questions concerning the tektite distribution are examined, taking into account the Australasian strewn field, the Ivory Coast strewn field, the Moldavite strewn field, the North American strewn field, the Libyan desert glass, the Aouelloul crater glass, and amerikanites. Attention is given to the shapes of tektites, the internal structure of tektites, the physical properties of tektite glass, the chemical composition of tektites, isotopes, fission tracks, cosmic ray tracks, and arguments in favor and against the terrestrial origin of tektites. It is concluded that tektites cannot be terrestrial in origin. They are probably volcanic ejects, of geologically recent epochs, from one or a number of lunar volcanoes.
