  2. Seabed mining - Wikipedia

    en.wikipedia.org/wiki/Seabed_mining

    Model of seabed mining technology. Seabed mining, also known as Seafloor mining [1] is the recovery of minerals from the seabed by techniques of underwater mining. The concept includes mining at shallow depths on the continental shelf and deep-sea mining at greater depths associated with tectonic activity, hydrothermal vents and the abyssal plains.

    Chief designer Ye Cong said the seabed was abundant with resources and a "treasure map" can be made. [39] Promising sulfide deposits (an average of 26 parts per million) were found in the Central and Eastern Manus Basin around Papua New Guinea and the crater of Conical Seamount to the east. It offers relatively shallow water depth of 1050 m ...

    Mineral associations may vary (1) in different mineralized structures, either syngenetic (namely, passive precipitation in chimneys, mounds and stratiform deposits) or epigenetic (structures that correspond to feeder channels, and replacements of host rocks or pre-existing massive sulfide bodies), or structural zonation, (2) from proximal to ...

    Norway has paused its controversial project to open up its seabed for commercial-scale deep-sea mining. Oslo had planned to let companies apply to mine 280,000 sq km (108,000 sq miles) of its ...

  9. Seabed - Wikipedia

    en.wikipedia.org/wiki/Seabed

    The seabed (also known as the seafloor, sea floor, ocean floor, and ocean bottom) is the bottom of the ocean. All floors of the ocean are known as 'seabeds'. The structure of the seabed of the global ocean is governed by plate tectonics. Most of the ocean is very deep, where the seabed is known as the abyssal plain. Seafloor spreading creates ...
