Jan 15 2021The MidAtlantic Ridge belongs to slowspreading ridges. Hannington predicted that there were a large number of mineral resources on slowspreading ridges however seafloor massive sulfide deposits usually develop thousands of meters below the seafloor which make them extremely difficult to explore. Therefore it is necessary to use mineral prospectivity mapping to narrow the exploration
