The “king” is here! The Yarrabubba impact crater was found in Australia and is the most prominent crater from his “family.” It has no less than 190 “brothers and sisters,” and he is the oldest one. Until recently, the oldest crater that we’ve known about was the one from the Vordefort Dome in South Africa, age: 200 million years old.
Scientists are trying to evaluate the impact of the craters that might relate to the formation of the continents. Due to his ability to “camouflage,” Yarrabubba crater, has about 70 km wide and looks like common ground.
Because of its composition, rocks, sand, and all kind of sediments, the weather wasn’t so friendly with our crater. During the rainy season, water made its way and transformed the crater almost into a usual rocky hill. The type of rock has the minerals zircon and monazite inside that may contain uranium.
Australian Yarrabubba Impact Crater Is The Oldest One On Earth
Professor Chris Kirkland from Curtin University said: “Now we know the Yarrabubba crater was made right at the end of what’s commonly referred to as the early Snowball Earth – a time when the atmosphere and oceans were evolving and becoming more oxygenated and when rocks deposited on many continents recorded glacial conditions.”
Yarrabubba meteor, like all meteors, had a significant impact on climate change. The scientists said that from the impact with Earth, the meteors “helped “our planet to lose the glacial deposits. When it got through the atmosphere and landed on Earth, the area was covered in ice, after the impact, all the ice was vaporized, and now all we can see is a rocky place.
Yarrabubba is about half the age of the Earth, and it raises the question of whether all older impact craters have been eroded or if they are still out there waiting to be discovered.
