The Researchers discovered that the piezo catalytic effect of quartz under seismic stress causes the accumulation of gold in quartz veins.
Orogenic gold systems are commonly found in mountainous regions where large-scale geological processes, such as the collision of tectonic plates, have occurred.
The Large gold nuggets are often found in orogenic quartz veins formed during the tectonic processes that create mountains.
These nuggets form because, during earthquakes, the stress on quartz crystals causes a reaction that deposits gold on their surfaces.
This process happens repeatedly leading to the accumulation of gold nuggets.
