In the icy territory of Antarctica, stands the southernmost volcano on the planet: Mount Erebus. This giant of nature releases about 80 grams of gold crystals daily in the form of tiny particles, which the polar winds disperse up to 1,000 kilometers away. Scientists have determined that these particles measure less than 20 micrometers.
Considered a “unique natural laboratory,” Mount Erebus offers researchers the opportunity to study the ascent of magma from the Earth’s crust to the surface. Geological analyses have identified that the gases emitted from this volcano contain not only gold but also traces of silver and copper.
Mount Erebus and its Flying Gold Crystals
Located on Ross Island, Mount Erebus rises 3,794 meters above sea level. It is one of the few volcanoes in the world that maintains a permanent lava lake in its crater. This particularity gives it special interest to volcanologists studying its activity.
Experts point out that Erebus’s magma is rich in alkaline elements, with a unique composition that facilitates the presence of precious metals in the gases released during its frequent Strombolian eruptions. These explosions are moderate eruptions of gas-rich basaltic magma that eject pyroclasts hundreds of meters into the air, creating luminous trails.
Contacting the frigid Antarctic air, the vapors emitted by Erebus cool rapidly, condensing the minerals into solid crystals. These tiny crystals are then dispersed by the strong winds of the region, explaining the finding of gold particles at great distances from the volcano.
Research has recorded the presence of these particles up to nearly a thousand kilometers from the point of origin, confirming Mount Erebus’s ability to release precious metals over long distances. Through a recent study, the use of artificial intelligence has allowed the discovery of hundreds of hidden earthquakes beneath the Antarctic ice, increasing scientific interest in this remote area.
