SD Earth’s hidden “gold kitchen” lies beneath the seafloor

[admin]

Deep beneath submarine volcanoes, Earth may be running a natural “gold kitchen.” By analyzing volcanic glass from the Kermadec island arc north of New Zealand, researchers found that water-rich mantle repeatedly melts beneath subduction zones, gradually concentrating gold in rising magma. The process works because intense melting breaks down sulfur-rich minerals that normally trap gold, releasing the metal into the melt.
