A recent study titled 'Gold nugget formation from earthquake-induced piezoelectricity in quartz', published in Nature Geoscience and led by scientists from Monash University, has found that earthquakes may be key to how gold nuggets form. The research explains that the pressure exerted on quartz crystals during seismic activity generates electricity via piezoelectric effects. This electrical charge triggers electrochemical reactions which transform dissolved gold in geological fluids into solid particles that accumulate on the quartz.

Laboratory experiments confirmed that the voltage generated by deforming quartz is sufficient to induce the precipitation of gold and the formation of nanoparticles, which serve as growth nuclei. Furthermore, the presence of existing small gold fragments aids in the accumulation of new layers, allowing small deposits to evolve into gold nuggets. This discovery provides insights into geochemical processes at play during seismic events, highlighting the intersection of geology and natural resource formation.

Understanding the processes behind gold nugget formation not only sheds light on geological phenomena but could also have implications for mining strategies and resource management. As gold continues to hold significant economic value, this research may influence how resources are explored and extracted in the future, making it a pertinent topic in both scientific and economic discussions.
