The impact of an asteroid on the Earth always fascinated scientists. The asteroids bring different materials from outer space on the Earth. This has triggered tremendous research inside the craters created by the asteroid impact.
According to Andrew Gilkson, asteroid expert, one of the largest asteroid impact must have occurred in Australia. The proofs for the same are buried under the Australian crust, somewhere near the East Warburton Basin, located in the central part of the continent.
During his study in Australia, he discovered crater with a diameter of 125 miles. Australian National University expert Gikson also added that he found the size of the terrain around 200 kilometers, which ranks third in the world.
The researcher believes that the impact of the asteroid was global, resulting into high concentration ash in the atmosphere and low sunlight. This must have affected living beings at that time and Gikson believes that it has some links with mass extinction.
In a research paper published in Tectonophysics, a geology journal, Andrew Gikson notes that the asteroid was a large structure, divided into two parts of 200 kilometers each in the diameter. But he is still not being able to find out the time period of the event.
The rough estimates by Gikson suggest that the event occurred around 300 million years ago, but he is unable to find any mass extinction during that period. He assured significant role of this impact in the evolution of life on the earth. Rock converted into a glass and deep domes were important evidence found during the excavations.
