Mount Erebus volcano emits microscopic gold particles in Antarctica

Mount Erebus, an active volcano located on Ross Island in Antarctica, is known for emitting microscopic gold particles through its gas plumes. The 3,794-meter-high volcano features a permanent lava lake within its crater, which continuously releases hot gases and ash clouds.

Research published in Geophysical Research Letters has identified that halogen-rich gases bind with trace amounts of precious metals. When these gases encounter the extreme cold of the Antarctic air, the mixture cools abruptly, causing the atoms to condense into fine gold dust that settles in the snow. While these particles have been detected in air and snow samples up to 1,000 kilometers away, they do not form economically viable deposits.

The area surrounding Mount Erebus is a strictly protected research zone near McMurdo Station, making it inaccessible to general tourists. The phenomenon serves as a significant scientific example of how specific gas reactions can make trace metals measurable.
