- Title: Atlantis II Deep - marine minerals and geomorphic setting
The Atlantis II Deep is in the central Red Sea. The deep attains a depth of over 2100 meters and is situated in the Red Sea rift, where the Arabian Peninsula and Africa are being split apart. Surveys in the 1960's confirmed the presence of hot, 60 °C, saline brines and associated metalliferous muds. The Atlantis II Deep has the biggest known metal-rich sea-floor deposit discovered to date, and it is by far the only example of a large-scale metalliferous-sediment type deposit. In the 1970s, a pre-pilot test mining study was conducted by a Saudi Arabian company (Preussag A. G.). Using what was described as “conventional floatation” means, they recovered 15,000 m3 of sea floor sediments and brines from four test sites in the Atlantis II basin. They also proceeded to concentrate the recovered material at sea. GRID-Arendal has been working on an environmental analysis of marine mineral deposits such as this as part of an assessment of Marine Minerals for the European Union.
