On the Moon found the oldest stone of the Earth – Technology

Scientists from Sweden, Australia and the United States analyzed samples of the lunar soil collected as part of the Apollo-14 mission and found there particles of could not form on the moon. According to researchers, they arrived at our planet's satellite from Earth about four billion years ago

. The launch of the Apollo 14 mission took place in 1971. Then, a third landing on the moon was made, during which astronaut Edgar Mitchell collected lunar soil samples. During a new study, scientists analyzed these samples and suggested that some of them had fallen on a satellite of the Earth 3.9 billion years ago

. Fragments of quartz, feldspar and zircon were found in the images. In addition, a chemical analysis showed that the rock was formed in an oxidized environment at temperatures characteristic of the Earth. Assuming that it formed on the Moon, given the pressure of crystallization, it occurred at a depth of 167 km, which is extremely unlikely, not to mention the level of oxygen which had a satellite four billion years ago.

Determine that the breed was formed 4-4.1 billion years ago, probably at a depth of 20 kilometers. According to researchers, 3.9 billion years ago, an asteroid that threw part of the rock into space fell to the Earth. As the moon was on our planet three times closer than now, the wreckage has settled on its surface.

Earlier scientists have stated that on the moon are possible "black" (1945). The moon is compressed and deformed under the influence of Earth's gravity. Recently, a crack was discovered on the planet's satellite.
