More Precious Than Gold: Miners in Australia Find 100 Million Year Old Meteorite

Modern technology, such as electromagnetic surveys that map rocks beneath the surface, is making it more common to locate hidden meteorite craters, with experts hoping to make many more notable discoveries ahead.

Australia’s third largest gold mine, an area of ​​land owned by development mining, has made a sensational discovery that has nothing to do with gold, but is no less priceless.

Geological Advisor Drs. A team of geologists led by Jason Meyers has claimed to have discovered a large meteorite pit in Western Australia, near the Goldfield mining town of Ora Banda, which can be up to five times larger than the famous Wolf Creek crater.

Determined after modern technologies such as electromagnetic and gravimetric mapping with a 5-kilometer diameter to map the outer rim and central uplift of the crater beneath the cliffs, it is considered one of the largest meteor bodies in the world is.

“The pit-forming asteroid must have been at least 100 meters wide. Based on its condition and erosion levels and some soil filling the sides, we estimate it to be around 100 million years old, ”Meyers was quoted as saying ABC.

The impact pit was located during drilling for gold.

Strangely, it would be impossible to imagine that the massive crater was there, as it is not visible from the surface.

“The discovery was made in an area where the landscape is very flat. You would not know that it was there because the crater is overcrowded with geological time, ”said Meyers.

The tell-tale sign

After the discovery of the pit, Drs. Meyers, who boasts 30 years of experience in the field and is an Assistant Associate Professor in Exploration Geophysics at the WA School of Mines, was brought in as a geological advisor.

Inspection of drilling samples from the site confirmed that the rock samples contained “tell-tale signs” of a meteorite strike. These are known as “shutter cones”. Under a microscope, they look like broken glass and form in a certain direction.

“But when you see the shattered cones you find out because they only happen as an effect of a nuclear explosion or a meteorite … We were convinced and very excited from a technical standpoint – it has nothing to do with gold , It is actually encircling gold. A bit – but we can hand over the heart that an asteroid hit the spot, “Meyers said.

The notable discovery is much larger than the Wolf Creek crater in WA Kimberley that was immortalized in the 2005 Australian horror film Wolf Creek.

Dr. Meyers suggested that more exciting discoveries could be expected, with new technology constantly evolving to aid geologists, citing several other suspected asteroid impact areas at their sightseeing in Washington.
