Scientists from Australia (University of Curtin) found that huge Yarrabubba Crater, located in the western part Australia, arose 2.2 billion years ago as a result of the fall meteorite. It turns out that this crater is the oldest of famous scientists. This was reported on the site Phys.org.
According to experts, the exact age of the crater, the size of which about 70 kilometers, is about 2.229 billion years. Among such places as this crater is 200 years older than any of them million years. Experts have established this as a result of analysis monazite and zircon discovered at the site of the fall of the ancient celestial body. Using SHRIMP technology, researchers crystalline fragments were scanned and more accurate the time of the fall of the meteorite to Earth.
However, experts found that the age of the ancient crater, left by the “space alien” coincides with the time completion of the complete glaciation of the Earth. That period in the history of our Researchers call planet Earth “Snowball.” For 400 million years after a meteorite fall no trace was found glacial deposits. The collision of a celestial body with the Earth has evaporated about 1.5 trillion tons of ice, and water vapor trapped in atmosphere, contributed to the warming up of our planet.
