Deep-Ocean Mineral Deposits: Metal Resources and …

Major deposits of metalliferous, sulfide-rich sediments were discovered beneath the Red Sea in the mid-1960s, at what is known as the Atlantis II Deep. Although volcanism was long considered a potential source of metals to the marine environment (e.g. Murray and Renard 1891), and seafloor hydrothermal activity had been postulated, direct, visual verification only came with the discovery of ...
