👉 Recently, scientists have uncovered a unique fluid deep within the Earth's mantle that behaves differently from previously known materials. This newly discovered fluid, dubbed "mantle brine," is a highly saline, low-viscosity liquid that exists at temperatures and pressures far beyond those of typical Earth fluids. It is rich in dissolved minerals and gases, including water, carbon dioxide, and various metals, which significantly lower its viscosity and enable it to flow more freely. This discovery challenges our understanding of mantle dynamics, suggesting that fluid movement within the Earth's interior could play a more critical role in heat transfer and chemical cycling than previously thought. The implications of this fluid extend to our understanding of plate tectonics, volcanic activity, and even the potential for life in extreme environments on Earth and other planets.
