Earthquakes may help prospectors strike gold: When these seismic events stir and squeeze quartz veins deep underground, the mineral creates an electric field that gold particles clump to, forming ...

Electric currents in the Earth may be responsible for the formation of gold nuggets, new research suggests. As detailed in a new study published in the journal Nature Geoscience, the theory could ...

For centuries, scientists have wondered why Earth has a magnetic field. It's still a mystery, but by using super-high pressures and temperatures to duplicate conditions at the Earth's core, scientists ...
