Subject: The problem of tektite origin.
Wherever it came from, it completely ignores the fact that all layered
tektites exhibit (e.t.) megascopic volcanic structures. Many also exhibit
microscopic volcanic structures (including welded breccias, some buried
under subsequent deposits of microtektites, plus welded faults). Since some
of these microscopic structures require at least ten minutes to form, at
their source of origin (1986, Nature 319, 663-665), there is no way they
could have been ejected over 1,000 km in an impact (a requirement of their
distribution in the Australasian strewnfield). Any discussion of tektite
origin that ignores these established facts is highly misleading, no matter
who the author.
