how earthquakes trigger quartz into forming large gold nuggets

Earthquakes can trigger quartz into forming giant gold nuggets, study
finds

Geologists have known for decades that gold forms in quartz with the
help of earthquakes, but now they have worked out exactly how the
setting and seismic waves combine to form large nuggets.

"When you actually put it together, it almost works out a bit too
neat," Voisey said. The researchers found that earthquakes fracture
rocks and force hydrothermal fluids up into the quartz veins, filling
them with dissolved gold. In response to the stress of the earthquake,
quartz veins simultaneously generate an electric charge that reacts
with the gold, causing it to precipitate and solidify.
