Everyday is seems we learn more and more about gold, its properties and some of the ways nature actually produces it.
In fact, aside from this article, which is an interesting case of how gold is formed, did you know that there are plants that suck gold out of the ground? Or there is gold free floating in sea water? That there are bugs that poop gold?
There are really some interesting ways gold is made by mother earth. Earthquakes have the Midas touch, a new study claims.
Water in faults vaporizes during an earthquake, depositing gold, according to a model published in the March 17 issue of the journal Nature Geoscience. The model provides a quantitative mechanism for the link between gold and quartz seen in many of the world’s gold deposits, said Dion Weatherley, a geophysicist at the University of Queensland in Australia and lead author of the study.
When an earthquake strikes, it moves along a rupture in the ground — a fracture called a fault. Big faults can have many small fractures along their length, connected by jogs that appear as rectangular voids. Water often lubricates faults, filling in fractures and jogs.
About 6 miles (10 kilometers) below the surface, under incredible temperatures and pressures, the water carries high concentrations of carbon dioxide, silica and economically attractive elements like gold.
