Gold has always been a hot commodity. But these days, finding a nugget isn’t too tricky: Much of the world’s gold is mined from natural veins of quartz, a glassy mineral that streaks through ...

The stress and strain produced by moving tectonic plates during such an event may trigger a chemical reaction that causes minuscule particles of gold to coalesce into larger nuggets, a new study ...

Findings suggest gold nuggets can form in quartz veins as a result of electricity produced by the pressure of earthquakes. The gold is carried in super-hot liquids from the Earth's core to its ...

Geologists understand this process quite well, but large gold nuggets have been a bit of a mystery. Gold is only dissolved in natural fluids at around one part per million, so how does it ...

The findings explain how fluids carrying meager amounts of gold can concoct large nuggets, even in chemically inert settings. “You find a 2-meter-wide quartz vein, and there’s a big gold ...

HELENA, Mon., Jan. 25.—A forty-two- pound gold nugget worth upward of $10,000 is reported to have been found in California Gulch, one of the tributaries of the famous Alder Gulch, in Madison County.

An Australian couple was searching for gold using a metal detector in the Kalgoorlie Goldfields in 1979 when they uncovered the largest gold nugget found in the region in the previous 50 years.

“It has been estimated that all of the Gold ever mined could fit in a cube measuring roughly 22 meters (72 feet) in each direction. Very little remains in a natural nugget state, with the vast ...
