Seafloor massive sulfide (SMS) deposits are economically significant mineral resources found on the ocean floor, typically at hydrothermal vent areas where hot, mineral-rich fluids are expelled from the Earth's crust. These deposits are primarily composed of sulfide minerals, including copper, lead, zinc, and precious metals like gold and silver.
