In an interesting turn of events, a man found a piece of rock, brought it home thinking it to be gold rock, kept it for years and it turned out to be more valuable than even gold. The interesting big of information came from Jacinta Bowler datelined December 27, 2019 in “Science Alert” on the basis of research published in the “Proceedings of the Royal Society of Victoria”.
The story goes on like this that In 2015, one David Hole was prospecting in Maryborough Regional Park near Melbourne, Australia. Armed with a metal detector, he discovered something out of the ordinary — a very heavy, reddish rock resting in some yellow clay. He took it home and tried everything to open it, sure that there was a gold nugget inside the rock — after all, Maryborough is in the Goldfields region, where the Australian gold rush peaked in the 19th century.
To crack open his find, Hole tried a rock saw, an angle grinder, a drill, even putting the thing in acid, but not even a sledgehammer could make a crack. That’s because what he was trying so hard to open was no gold nugget. As he found out years later, it was a rare meteorite.
“It had this sculpted, dimpled look to it,” Melbourne museum geologist Dermot Henry told The Sydney Morning Herald. “That’s formed when they come through the atmosphere, they are melting on the outside, and the atmosphere sculpts them.”
Unable to open the ‘rock’, but still intrigued, Hole took the meteorite into the Melbourne Museum to be identified.
“I’ve looked at a lot of rocks that people think are meteorites,” Henry told.
In fact, after 37 years of working at the museum and examining thousands of rocks, Henry explains only two of the offerings have ever turned out to be real meteorites.
This was one of the two
“If you saw a rock on Earth like this, and you picked it up, it shouldn’t be that heavy,” another Melbourne Museum geologist, Bill Birch told.
The researchers have recently published a scientific paper describing the 4.6 billion-year-old meteorite, which they’ve called Maryborough after the town near where it was found.
It’s a huge 17 kilograms (37.5 pounds), and after using a diamond saw to cut off a small slice, they discovered its composition has a high percentage of iron, making it a H5 ordinary chondrite.
The rock measures 38.5cm x 14.5cm x 14.5cm and weighs 17 kilograms. The specimen is quite rare being one of only 17 meteorites ever recorded in Victoria. It is also the second-largest chondritic mass, after a 55-kilogram meteorite found in 2003. This begs the question what other simple looking rocks out there could actually be rare meteorites?
Once open, you can also see the tiny crystallized droplets of metallic minerals throughout it, called chondrules.
“Meteorites provide the cheapest form of space exploration. They transport us back in time, providing clues to the age, formation and chemistry of our Solar System (including Earth),”
“Some provide a glimpse at the deep interior of our planet. In some meteorites, there is ‘stardust’ even older than our solar system, which shows us how stars form and evolve to create elements of the periodic table.
“Other rare meteorites contain organic molecules such as amino acids; the building blocks of life.”
Although the researchers don’t yet know where the meteorite came from and how long it may have been on Earth, they do have some guesses.
Our Solar System was once a spinning pile of dust and chondrite rocks. Eventually gravity pulled a lot of this material together into planets, but the leftovers mostly ended up in a huge
“This particular meteorite most probably comes out of the asteroid belt between Mars and Jupiter, and it’s been nudged out of there by some asteroids smashing into each other, then one day it smashes into Earth,” Henry said.
Carbon dating suggests the meteorite has been on Earth between 100 and 1,000 years, and there’s been a number of meteor sightings between 1889 and 1951 that could correspond to its arrival on our planet.
The researchers argue that the Maryborough meteorite is much rarer than gold. It’s one of only 17 meteorites ever recorded in the Australian state of Victoria, and it’s the second largest chondritic mass, after a huge 55-kilogram specimen identified in 2003.
Henry told, “This is only the 17th meteorite found in Victoria, whereas there’s been thousands of gold nuggets found.” Looking at the chain of events, it’s quite, you might say, astronomical it being discovered at all.” It’s not even the first meteorite to take a few years to make it to a museum. In an amazing story, we covered last year, one space rock took 80 years, two owners, and a stint as a doorstop before making it to a museum.
Now is probably as good a time as any to check your backyard for particularly heavy and hard-to-break rocks — you might be sitting on a metaphorical gold mine.
Interestingly, once upon a time, gold was the basis for sound money. Gold has long been a measure of wealth, and it is still coveted the world over for jewelry and as a store of wealth.
Throughout history, people have literally traveled to the ends of the earth in search of the yellow metal. Silver is often said to be gold’s ugly sister. Perhaps not as aesthetically pleasing as gold, silver is much cheaper to gain exposure to — and is quite possibly a better long-term investment than gold.
Platinum and its close cousin, palladium come next. Platinum is much rarer than both gold and silver and palladium is even rarer than that. The vast majority of platinum comes from South Africa. Palladium is even rarer than platinum, and certainly less talked about. Palladium is in the platinum family of metals, and jewelry connoisseurs know it as an alternative to gold or platinum.
One reason for its growing value is the simple fact that palladium deposits are rare, with major mines in Russia, South Africa, Ontario and Montana. Overall, it’s estimated about 110,000 tons of platinum-group metals are held in reserve around the world, with nearly 70,000 tons held in South Africa. The research has been published in the “Proceedings of the Royal Society of Victoria.
