We think of impact events as being disastrous for life,” said Dr. Nadja Drabon, a Harvard geologist whose recent research is ...

Along with colleagues from universities and science centers in Germany, Egypt, and Morocco, I have identified Libyan desert glass as originating from the impact of a meteorite on the Earth's surface.

which Sieh believes are the detritus of a land-stripping impact blast. The tektites, a type of natural glass formed when meteorites hit sandy surfaces, were found near the tops of these gravels ...

In the rock layers, the researchers could see spherules, which are tiny, glass-like orbs that form when silica-containing rock melts due to a meteorite impact. They also observed conglomerates ...

This would help determine whether their formation was due to volcanic activity or meteorite impact. The results revealed that the silicate glass was created by meteorites that impacted the basalt ...

The study also found that major impact events on Earth were not ... The heat and pressure of meteorite impacts created the glass beads and so their age distribution should mimic the impacts ...

An Austrian astrochemist Christian Koeberl had established that the glass had been formed at a temperature so hot that there could be only one known cause: a meteorite impacting with Earth. And yet ...

On a young Earth, giant meteors might have been a harbinger of life, not death. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. The ...

Scientists have found minerals around its edges that match the composition of these glass beads. If the beads are truly ...

Analysing the silicate glass beads, researchers could open ... whether they were formed by volcanic activity or via meteorite impact. Recommended Moon’s poles shifted over 4 billion years ...
