Tektites ranging from 750,000 to 35.5 million years old have been discovered across the planet in areas known as strewn fields, which can be found on every continent except Antarctica.

Nor can tektites be meteorites that moved on orbits in the solar system, says Kohman. The fragments of single stony meteorites could not cover large areas of the earth’s surface, ...

Like Hansel and Gretel followed a trail of breadcrumbs, scientists have followed glassy particles called tektites (some shown) to the sites of major meteorite impacts around the world. rep0rter ...

THE suggestion first made in NATURE (131, 117; 1933) by Dr. L. J. Spencer that tektites have been formed by the fusion of terrestrial rocks by the fall of very large meteorites has given rise to ...

It has been argued that the glassy stones called tektites arose from the impact of huge meteorites on the earth. There are also arguments that they originated with similar impacts on the moon ...

A further possible objection that no tektite hitherto described contains so many vesicles as glass from meteorite craters is discounted by Prof. A. Lacroix's description of 95 kgm. of tektites ...
