Recent research has uncovered a surprising connection between earthquakes and the formation of gold beneath the Earth's surface. Australian geologists suggest that the lightning generated Earthquake Lightning Leads to Gold Formation Beneath Earth's Surface, Shocking Scientists earthquakes could be the reason behind the creation of large gold nuggets in massive rocks below ground. This groundbreaking discovery has sent shockwaves through the world of science.
How is Gold Formed?
For years, scientists have tried to understand how gold is formed deep within the Earth. Chris Voisey, the lead researcher from Monash University, explains, "It is believed that gold emerges from hot, water-rich fluids that flow through cracks in the Earth's crust. When these fluids cool down or undergo chemical changes, the gold separates and gets trapped in quartz veins."
However, Voisey pointed out that although this theory is widely accepted, it doesn't fully explain how large gold nuggets are formed, especially considering that these fluids contain very low concentrations of gold.
Testing a 144-Year-Old Theory
To address this mystery, researchers tested a new theory based on *piezoelectricity*. This concept was first discovered in 1880 by French physicists Jacques and Pierre Curie, the latter being the husband of the famous physicist Marie Curie. Piezoelectricity occurs when certain solid materials, like quartz, convert mechanical energy into electrical energy or vice versa.
The team theorized that the mechanical stress generated during an earthquake might produce piezoelectricity in quartz, which could then trigger the electrical and chemical reactions necessary to form large gold nuggets.
Surprising Results
To test their hypothesis, the team replicated the conditions that occur in quartz during an earthquake. Quartz crystals were submerged in gold-rich fluids and subjected to mechanical stress using a motor. These samples were then studied under a microscope.
Andy Tomkins, a co-author of the study, revealed, "The results were astonishing. The stressed quartz not only electrochemically deposited gold onto its surface but also created and accumulated gold nanoparticles. Rather than creating new gold particles, the existing ones tended to accumulate more gold."
This phenomenon occurs because quartz acts as an electrical insulator, while gold serves as a conductor.
The Global Value of Gold
Gold has been considered valuable for centuries due to its brilliance, rarity, and colour. Beyond jewellery, gold is essential in computers and communication devices. According to the United States Geological Survey (USGS), approximately 244,000 tons of gold have been discovered to date, with about 57,000 tons still remaining in underground reserves. All the gold found so far could fit into a cube with 23-meter-long sides.
This new discovery about gold formation beneath the Earth's surface has left the scientific community in awe, shedding light on yet another fascinating aspect of our planet's mysteries.
Conclusion
The findings from Monash University’s research on piezoelectricity during earthquakes could change the way we understand the formation of large gold nuggets. These results also suggest that even more undiscovered natural processes might contribute to the Earth's hidden wealth. With more study, we may continue to unlock the secrets of how precious materials like gold come to be, deep beneath our feet.
