A new study has shed light on the mechanism behind gold’s formation deep inside the Earth and its journey to the surface. Researchers at the University of Michigan used advanced computer models to understand how magma becomes enriched with gold. The key to this process lies in a special type of sulfur that only exists under high-pressure and high-temperature conditions found near active volcanoes.
When this sulfur is present, it helps transport gold from the Earth’s interior into molten rock. This gold-rich magma then travels towards the surface, where it can form deposits. The study is significant as it provides a solid scientific model for understanding how gold bonds with sulfur ions.
The research team replicated conditions in laboratory experiments to develop their model. According to Adam Simon, U-M professor of Earth and environmental sciences, “Active volcanoes around the Pacific Ocean are creating environments that can lead to the formation of gold deposits.” This model can now be used to understand real-world conditions in the Earth’s mantle, shedding light on the complex processes involved in gold formation.
