The Link Between Earthquakes and Gold Nuggets
Earthquakes may play a crucial role in the formation of gold nuggets due to their impact on quartz. Researchers have found that quartz, when stressed or shaken, generates electricity through a phenomenon known as piezoelectricity. In experiments, quartz slabs exposed to simulated seismic waves attracted gold particles, while control slabs did not show this effect. This discovery reshapes the understanding of how gold forms in the Earth, suggesting that gold nuggets can develop from small particles over long periods of time and geological activity.
