In 2015, David Hole was out exploring Maryborough Regional Park near Melbourne, Australia, with his trusty metal detector. He stumbled upon a heavy, reddish rock buried in yellow clay. Thinking he’d found a gold nugget—after all, Maryborough was famous for its gold rush in the 19th century—he took it home and tried everything to crack it open. He used a rock saw, an angle grinder, and even acid. But nothing worked; the rock wouldn’t budge.
Eventually, David discovered that this tough rock was not gold at all, but a rare meteorite.
Dermot Henry, a geologist at the Melbourne Museum, explained that the meteorite had a dimpled look caused by its entry through the Earth’s atmosphere. As it burned up, the outer layer melted and formed this unique texture.
Curious about his find, David took the rock to the museum for identification. Henry, with over three decades of experience, noted that out of the thousands of rocks he’d examined, only two ended up being genuine meteorites. This was one of them.
Bill Birch, another geologist at the museum, added that the meteorite weighed an impressive 17 kilograms (around 37.5 pounds). It was classified as an H5 ordinary chondrite, rich in iron. Researchers even sliced it open to find tiny droplets of metallic minerals called chondrules inside.
Meteorites are fascinating, offering a window into both time and space. They tell us about the formation of our Solar System and sometimes even contain organic molecules, like amino acids, which are essential for life.
This meteorite, which they aptly named Maryborough, is potentially billions of years old. Experts believe it likely originated from the asteroid belt between Mars and Jupiter, ejected into space by collisions and eventually landing on Earth. Carbon dating suggests it has been here for 100 to 1,000 years, with some meteor sightings in Victoria during that time.
Interestingly, the Maryborough meteorite is one of just 17 ever recorded in Victoria, making it much rarer than gold nuggets. Henry noted that the odds of finding such a meteorite are astronomically low compared to the many gold pieces found in the region.
In a broader context, the study of meteorites continues to evolve. Recent research has linked over 90% of meteorites back to their parent bodies in space, providing invaluable insights into the cosmos. This ongoing work highlights the chance for anyone to find a hidden treasure in their backyard—perhaps even a meteorite like David Hole did.
