SYDNEY: The scientists have several kinds of evidence suggesting the Australian craters were formed during one or two meteorite smash, revealed a study.
The study was published in Tectonophysics this month. After facing tough time and different controversies, findings confirmed impact craters at Earth’s surface, much less those buried beneath 3 kilometres of sediment.
“Each measuring 200 kilometres across, two mysterious natural structures buried deep in central Australia could be some of the world’s biggest impact craters,” as per the team of Australian geologists. Andrew Glikson, a geologist at the Australian National University in Canberra and Lead author of the study stated, “I’m sure there will be a lot of people raising eyebrows,” says,. “But I think we have a major body of evidence for an impact origin.”
According to the structures, near the border between South Australia and the Northern Territory, in the Warburton Basin where geologists have long hunted for oil and gas as well as geothermal resources. Those data have yielded handsome knowledge about what is buried beneath the surface. Seismic studies have already pointed to the fact that something is distorting the crust beneath the eastern and western Warburton Basin. Gravity and magnetic studies also imply the presence of some kind of buried structure.
