Scientists at the University kertina in Australia revealed the origin of glass formations, which are found in the Eastern part of Libya and Egypt. The researchers came to the conclusion that they were the result of a meteorite impact on the earth. About it reported in a press release .
Natural glass from the Libyan desert, which spreads over an area of several thousand square kilometers, has a beautiful yellow tint. According to calculations, it was formed 29 million years ago. The material often used by jewelers since the days of the Egyptian pharaohs. In particular, they are decorated with a scarab in the pectoral found in the tomb of Tutankhamun.
In science, there were two hypotheses about the formation of this glass. One of them – it came from a meteorite impact on the earth, and on the other – as a result of atmospheric explosion of an asteroid. Thorough research conducted by Australian scientists, gave reason to doubt the latter hypothesis.
The samples had traces of mineral reidite, which is formed under high pressure, for example, when a meteorite impact. Reedit is found only in impact craters.
Experts believe that the inclusions of reidite in pieces Libyan glass is a reliable confirmation of the impact hypothesis of the formation of this material. According to one of the study’s authors Aaron’s Kavosi, discovery is an unexpected result which gives us confidence in the future of the Earth. After all, once the planet survived the impact with the largest meteorite.
Previously, scientists have explained the phenomenon of the “fire” of the mountain, from the summit of which for two thousand years, erupting a flame. The mountain is located in the South-West of Turkey. Its description can be found in the texts of Homer. Modern researchers have found that the combustion support gas that seeps through cracks in the surface of abiotic methane. The reason for its appearance – a chemical reaction inside the mountain.
