The found piece of gold turned out to be an even more valuable stone

In 2015, an Australian resident named David Holeengaged in the search for metals in a regional park called Maryborough. Scanning the area with a metal detector, he found a very unusual stone under a layer of yellow clay, which was painted in reddish color and had a rather large mass. Since in the 19th century this Australian region was known as the location of large chunks of gold, the man thought that he had discovered a huge gold nugget enclosed inside a solid stone. He tried to break the outer layer with a saw, drill and even acid, but not one method was effective. David Hole found out that he managed to find a more valuable stone than a gold nugget only a few years later.

The find was described in Proceedings.of the Royal Society of Victoria. Suspecting that he was far from a gold nugget, the man turned to the Melbourne Museum for help. Museum staff, including geologist Dermot Henry, immediately suggested they were dealing with a meteorite. At the same time, they reacted to a heavy reddish stone with a share of skepticism, because many of the "meteorites" that people brought to the museum turned out to be ordinary cobblestones.

Valuable meteorite found in Australia

However, being interested in a large mass of stone,geologists still decided to study the composition of the stone, sawing it with a diamond saw. Inside it, they found a large number of tiny crystallized drops of metallic minerals, referred to as chondras. To the surprise of the museum staff, they really brought meteorite, and not ordinary, but chondrite. They explained that this type of meteorite is formed during sharp temperature changes during the meteorite entering the dense layers of the atmosphere.

The mass of the meteorite found is 17 kilograms

An unusual meteorite was called Maryborough and,According to researchers, it was formed in space 4.6 billion years ago. Its mass was an impressive 17 kilograms, and the asteroid belt between Mars and Jupiter is considered its homeland. Museum staff noted that between 1889 and 1951, astronomers observed several meteorite falls in Australia and the object found could well be one of them.

It is interesting: 6 largest meteorites discovered on Earth

This meteorite is especially valuable becausein the Australian state of Victoria, no more than 17 such space objects have been found in history. According to geologists, residents of the aforementioned state have a much greater chance of finding a gold nugget than a meteorite. In addition, the sample found is the second largest chondrite, and the largest is considered to be the 55 kg sample found in 2003.

According to researchers, this find is alsovery valuable because it can tell a lot about the history of our solar system. Since the age of the meteorite was estimated at 4.6 billion years, it probably contains elements that can make scientists understand how the planets closest to Earth formed.
