    • Hydrothermal
      A mineral-rich hydrothermal fluid may cool and crystallize at considerable depth with Earth’s crust and at comparatively high temperatures of 300°C to 500°C. in such an environment, a hypothermal mineral-rich deposit is formed.

      Hypothermal deposits, like other rock bodies formed deep within Earth, may subsequently be exposed through cycles of erosion lasting millions of years. Common in these deposits are minerals containing metallic elements such as nickel, cobalt, tungsten, arsenic, tin, and other economically valuable elements.
