Gold miners recently discovered a giant in the Australian Australian outback Meteor Crater back about 100 million years ago, when dinosaurs roamed the earth.
Found near the western Australian town of Aura Banda, the newly dubbed Aura Banda Impact Crater is around 3 miles (5 kilometers) away. This huge hole is probably 660 feet (200 meters) wide by a meteorite or longer than the length of two American football fields. According to Resourc.ly, Western Australia Australia News Outlet.
When geologists from Ev Australian gold mining company Evolution Mining came close to some unusual rock cores at Ora Banda, they approached a physics consultant and contracting company in Perth, the director of Resource Pentales and a potential founder of Resources. The mayor examined the original samples of the geologists’ drill, as well as rock samples from that quantity, and he immediately noticed signs of a disintegrating cone – a meteor crash.

When an effective object – such as a meteorite or a massive explosion (such as a nuclear test site), forms a high-pressure, high-velocity shock wave shutter cone – rocks an area, According to the Institute of Planetary Science (PSI), a Tucson-based for-profit group in Arizona that was not involved in the new discovery. The shock waves emit a distinctive vibe. Vimu the stone in the shape of a cone. Does, like a mark that a solid object can leave on an object’s windshield.
Because “we know they didn’t do any nuclear tests on Aura Banda,” the evidence suggests that an ancient impact hit the pit site, Meyers told Resources.
To learn more, Meyers examined the site’s topography (i.e. its various elevations) and examined the inconsistent map of gravity, which shows how Gravity The field at a particular site is different from a uniform, featureless earth According to NASA Earth ObservatoryIs, which was not involved in the search. Any gravitational anomalies that come up on the map can give an insight into the hidden features that affect the amount of mass in a given area, and therefore gravity pulls. For example, a mountain range has a gravitational force greater than a characteristic surface, while an ocean trench or pit has a negative gravitational anomaly, the Earth Observer explains.
The mayor’s work revealed a hidden effect crater with a pucker in the middle. This pucker is where the scattered rocks came back to the surface after the comet struck, bouncing back like a compressed spring, Resorkly.a reported. When geologists went to the “pucker” part of the site, they found a cone scattered in rocky outprops.
Now, scientists at Curtin University in Perth are examining the aura banda site at a microscopic level. In particular, the team will investigate whether the minerals on site were evaporated and then re-crystallized under high pressure. “When released energy release [meteorite] Each nuclear test to date would have had a greater impact than the combined energy release, “Meyers told ResourcesClean.
Research on zircons and other minerals from the open will likely be revealed when the meteor struck – right now, Meyers thinks it was hit 250 million to 40 million years ago. (If the Cretaceous period had ended about ace 65 million years ago, these meteors would not have bothered the non-avian dinosaurs, as they were already dead.)
The dinosaur-killing asteroids were much larger and more lethal. The asteroid, which now hit the Yucatan Peninsula area of Mexico, was about 6 miles (10 km) wide and its impact was about 90 miles (150 km) away.
