Actually, glass of tektitic composition is a good heat-shield material for space
capsules. A coincidence, perhaps, but it may be the reason why tektites survive
their high-speed flight. In any case, glasses of this type have been extensively ...

greater amount in the tektite substratum. 5. With very insignificant amounts of
aluminum oxide in many substrata of the upper mantle, its concentration is
sharply increased in all strata of the crust. The tektitic stratum in this case is
distinguished ...

If these spherules are related to the lower, kaolinitic layer of the K/T couplet in the
Western Interior of North America (Pollastro and Bohor, 1993), then these data
are consistent with decreasing concentrations and sizes of tektitic glasses with ...

If a rough value of 700°C. be assumed for the annealing point, and a value of 600
°C. be assigned for the strain point, it should be possible to determine an
annealing schedule for tektitic glass that would produce very little residual strain.

When used on synthetic glasses of tektitic composition, the method was shown to
be nonapplicable, and the data tend to support the concept that tektites have
been subjected to reducing conditions. Magnetic properties of ice The magnetic ...

The variations of the principal constituents are of the type that would result from
fractional volatilization of a melt of tektitic composition. The metallic spherules
discovered by Chao in the Philippine tektites range in diameter from 20ji to 0.8
