A study led by a marine geology team from Germany has revealed that undersea volcanic regions in the South Pacific Ocean, particularly near New Zealand, function as natural 'gold factories.' The research indicates that tectonic plate movements beneath the ocean floor cause rocks to melt, releasing fluids that are crucial for gold formation. In their analysis of 66 samples of volcanic glass formed from rapidly cooled lava, scientists found significantly high concentrations of gold compared to typical rocks. During the melting process, gold, which is often associated with sulfur, separates and travels with lava, eventually settling through hydrothermal vents on the ocean floor to form solid mineral deposits. This discovery suggests that areas previously considered ordinary may contain substantial reserves of gold and copper, enhancing our understanding of how valuable minerals are formed and potentially guiding future exploration of undersea resources.
