mineral deposits on the seafloor

  • Seafloor Minerals USGS

    2021-7-7 · The seafloor contains deposits of minerals that we we use in everyday life such as copper, zinc, nickel, gold, silver, and phosphorus. These deposits occur as crusts on volcanic and other rocks and as nodules on abyssal plain sediment that are typically Exploring for Mineral Deposits on the Seafloor with,2018-4-12 · mineral deposits on the seafloor. Similar to airborne TEM surveys conducted on land, marine TEM systems can use a concentric or coincident wire loop transmitter and receiver towed behind a ship. Such towed-loop TEM surveys could be further augmented by placing additional stationary receivers on the seafloor throughout the survey area.
