A team of Russian scientists is studying around 70 samples which were collected in the Iranian desert. Scientists say all samples have been measured and cataloged.
Around 13 kilograms of extraterrestrial materials whose properties are similar to those of meteorites have been discovered by a group of Russian investigators in an Iranian desert. The finding was made thanks to four geologists from the Ural Federal University who collected a large number of fragments in the Lut desert – southeast of the country – reports Sputnik News.
Sputnik Persian spoke with Viktor Grokhovsky a member of the Committee on Meteorites at the Academy of Sciences who said: “We planned to send an expedition to the Iranian desert Lut, intending to find a concentration of extraterrestrial material, meteorites.”
The scientific director of the group, Víktor Grojovski, explained that all the samples have been measured and cataloged. Researchers are evaluating their age and the exact time they separated from the parent body. The chief geologist believes that the materials are contemporaneous with the creation of Solar System and are about 4.5 billion years old. However, in order to confirm their exact age and origin further studies are due to be performed.
Interestingly, Researchers believe that 80% of the collected samples are fragments of meteorites, whose material was well-preserved thanks to the aridity and peculiarities of the terrain. Some of the fragments (at least 10 of the 70 samples) belong to a single type of material, so they could have been part of a rain of celestial bodies.
Speaking to Sputnik News, Mr. Grokhosvky said: “The team managed to collect a sufficient number of extraterrestrial materials, with the support of their Iranian colleagues from the University of Kerman. During the field work, about 13 kilograms of the samples, which is considered to be meteorite, were found. Half of the found fragments have remained with our Iranian colleagues; the other half has arrived at our test lab.”
“For now the samples have been measured and entered into the catalogue. In order to determine the age of the found fragments, the scientist should consider when a fragment was formed in space, when it split from its parent body and how much time has it spent on Earth.”
“Based on the isotopes it will be possible to talk about cosmogonist age, that is, how long the outer body of the meteorite was in the form of an asteroid,” added Mr. Grokhosvky.
