Deep-sea Fe-Mn Crusts from the Northeast Atlantic Ocean: Composition and Resource Considerations
Eighteen deep-sea ferromanganese crusts (Fe-Mn crusts) from 10 seamounts in the northeast Atlantic were studied. Samples were recovered from water depths of 1,200 to 4,600 m from seamounts near Madeira, the Canary and Azores islands, and one sample from the western Mediterranean Sea. The mineralogic...
