Tectites of Vietnam. Tectites Delivered By a Comet: A Hypothesis

Tectites (tektites) are mysterious natural acid glasses that differ dramatically from terrestrial volcanic or impact glasses. There are many arguments that speak in favor of their non-terrestrial origin, and that is why the problem of their origin has an important scientific and historical significance. It is no accident that hundreds of publications written by specialists of various fields from all over the world are devoted to this issue. It is discussed at length in a collection of articles entitled 'Tectites' (1963,1973), as well as in the excellent monograph by O'Keefe (1976).
