Tiny pieces of glass found scattered across Australia have revealed evidence of a previously unknown giant asteroid impact. This discovery centers on a new type of tektite, a natural glass formed when ...

Scientists thought that an Australian museum’s collection of tektites came from an 800,000-year-old asteroid strike on Earth. Some of them turned out to be much older. By Katherine Kornei Every few ...

Throughout the planet, there are only a handful of known tektite strewn fields, which are large swaths of land where natural glass (tektite) was strewn about after forming from terrestrial material ...

Researchers discovered a new field of ancient tektites in South Australia, revealing a long-forgotten asteroid impact. These 11-million-year-old glass fragments differ chemically and geographically ...

The chemical makeup of mineral inclusions preserved in impact glass hints at the site of a missing impact crater. Tektites are natural glass formed when debris falls back to Earth after a meteorite ...

Tektites, the natural glasses formed by the melting of terrestrial surface materials during high‐velocity meteorite impacts, offer a unique window into the dynamic processes that shape our planet.

A fundamental problem in the origin of tektites is the estimation of the composition and nature of the parent material from which they were derived. Of equal importance is the nature and complexity of ...

Scattered thinly over the earth’s surface are large patches of tektites—glassy lumps up to several inches across, of mysterious and probably unearthly origin. In Britain’s Nature, American Chemist ...

A spattering of miniscule glass "beads" found in the mountains of Antarctica may lead the way to an 800,000-year-old meteor impact crater. The tiny spheres, known as microtektites, are each no wider ...
