A huge three-mile-wide meteor crater formed about 100 million years ago was discovered by gold miners in the outback of Australia.
- A meteor crater was discovered in the outback of Western Australia
- The crater stretches for three miles and formed 100 million years ago
- The team found a shoot con on the spot, a sign of meteorite impact
- This form from the high-pressure, high-velocity shock waves produced by the big impact by the budget
Gold miners stumbled upon a large meteorite pit in the outback of Western Australia, which was formed about 100 million years ago.
Using electromagnetic surveys, the researchers were able to create images of the effective location, recognizing the aura banda crater below the surface to cross across, its surface is up to three miles long.
The shoot cone recovered from Earth was recovered from high-pressure, high-velocity shock waves produced by a large impacting object – ‘tell-tale signs of meteorite impact.’
Ancient plant material was also found in the silt, which will be further analyzed for microscopic pollen to collect a more accurate date of the hole that was filled.
Gold miners stumbled upon a large meteorite pit in the outback of Western Australia, which was formed about 100 million years ago. Using electromagnetic surveys, the researchers were able to create images of the surface impact site below, to determine if it stretched for three miles.
The miners were working near the historic Goldfields mining town of Ra Banda, northwest of Kalgorli-Boulder, when they saw rocks appearing outside the site.
Geologist and geophysicist Dr. Jay Jason Meyers said: ‘The Ora Banda pit was a gift.’
‘The geologists who were working on it were digging holes in gold, and they saw some very unusual rocks.’
‘They had in mind that this did not match anything they had seen and thought it could actually be the result of a meteorite.’
Shoot cones were found from the site, which is composed of a high-pressure, high-velocity shock wave produced by a large impacting object – ‘tell-tale signs of a meteorite effect’.
The miners were working near the historic Goldfields mining town of Ra Banda, near northwest of Kalgorli-Boulder, when they saw stones that appeared outside the site.
“Based on its condition and the level of erosion and some of the land that the sides are filling, we estimate it could be about 100 million years old,” he told ABC.
The team discovered silt with ancient plant material that paleontologists will detect microscopic pollen that can be analyzed when exactly the crate is filled.
Curtin University is helping mayors and will examine glass drops with cemented zircons and other minerals in the shoot cone to determine an exact date for when the impact occurred.
Although the team estimates that the crater is 100 million years old, they said it probably occurred 250 million to 40 million years ago.
Resonance and replacement stated that the zircons and other materials that had evaporated and re-crystallized in the hole would also shed light when this phenomenon occurred.
Meyers told Resource Ltd. that the energy released when the planet was affected would be greater than the combined energy released by each nuclear test.

Ore Banda Pit, however, is five times larger than Australia’s famous Wolfe Creek located further north in the Crater State. Wolf Creek was formed by a meteorite estimated to have crashed to Earth 1,000,000,000 years ago.
If the crater had hit during the Cretaceous period, it would not have affected the dinosaur age, which was the victim of a planet that left an impressive crater about a million miles away on the Yucatan Peninsula in Mexico about one million million years ago.
The Or Banda Pit, however, is five times larger than Australia’s farther north in the famous Wolf Creek Crater State.
Wolf Creek was formed by a meteorite that estimated to have crashed to Earth 1,000,000,000 years ago.
The meteorite left a huge 2,890-foot hole in the ground, visible on the surface.
And it was supposed to be the second largest pit in the world.
Killing dinosaurs: How to wipe a city-sized asteroid from the center of 75 percent of all animal and plant species
Non-avian dinosaurs were extinct about 65 million years ago and more than half the world’s species became extinct.
This mass extinction paved the way for the rise of mammals and the appearance of humans.
Chikaxulab asteroids are often cited as a possible cause of cretaceous-palaeogen extinction.
The asteroid has now plunged into the shallow sea where the Gulf of Mexico is.
The collision released a huge dust and soot cloud that changed the global climate, destroying 75 percent of all animal and plant species.
Researchers have claimed that the soot required for such global destruction could only come from the direct impact on the shallow water rocks around Mexico, which are particularly rich in hydrocarbons.
Within 10 hours of the impact, a tsunami swept across the bay, experts believe.

This caused earthquakes and landslides in areas as far as Argentina.
But at a time when there were waves and explosions the creatures weren’t just suffering from the waves – the heat was even worse.
While investigating the incident, the researchers found small particles of rock and other debris in the air as the planet crashed.
Known as spheres, these tiny particles cover the planet with a thick layer of soot.
Experts explain that the loss of light from the sun caused a complete collapse in the aquatic system.
This is because the phytoplankton base of almost all aquatic food chains would be gone.
It is believed that the evolution of more than 180 million years, which brought the world to the Cretaceous point, was destroyed in less time than the lifespan of Tyrannosaurus rex, which is about 20 to 30 years.
