The Hidden Role of Quartz in Gold Nugget Formation

Ancient gold mining practices reveal a strong connection between quartz and gold formations. Recent studies suggest piezoelectric properties of quartz play a significant role in the formation of large gold nuggets, as seen in earthquake-prone regions. Simulated lab experiments support these findings, indicating gold deposits grow over time due to seismic activity.

Recent research has shed new light on the long-standing mystery of how large gold nuggets form, suggesting a surprising partnership between gold and quartz. Historical gold mining, documented by Greek and Roman sources, has shown that major discoveries often occur in quartz veins.

Quartz, a piezoelectric material capable of generating electric charges under stress, likely facilitates this process. During earthquakes, the immense pressures put on quartz create significant electric charges, which might help gold atoms deposit onto surfaces, fostering nugget growth.

Lab experiments simulating earthquake conditions confirmed that stress-induced electric charges on quartz can cause dissolved gold to form nanoparticles and deposit onto existing gold grains. This discovery provides valuable insights into gold nugget formation over geological timescales and emphasizes the critical role of quartz in the process.
