Volcanic Treasures
Volcanic regions at the margins of continents act as hotspots for sulfur and metal accumulation, revealing Earth's natural mechanisms for resource concentration.
Sulfur Trails
As carbonate melts rise, they lose silica, triggering reactions that concentrate metals like cobalt and copper. Stephen Foley of Macquarie University describes this as nature’s “linear metal factory.”
