Earthquakes turn water into gold

At a depth of ten kilometers of the earth's crust have voids which at incredible temperatures and pressures flowing water. It carries particles of various minerals, including gold. During an earthquake, these voids become wider as the odds on them seismic waves.

The edges of the fracture in the crust move relative to each other, as a result, the pressure falls again - it is almost equal to the surface. Previously, the water fills the voids at a temperature of about 390 ° C instantly evaporates and silica, quartz crystals forming and gold remain in the form of a precipitate. Of course, then again, the emptiness filled with water due to the inflow from neighboring areas, but a small gold-bearing vein has already been formed.

Of course, the amount of gold in the core is small - in the best case would be a precious grain out of a million. However, in the area of ​​seismic activity is quite favorable for the development of the deposit can be formed for 100 000 years.
