    The recent discoveries of polymetallic sulfide deposits on the deep sea floor have created an interest in geophysical techniques for mapping them. A magnetometric resistivity method (MINI-MOSES) has been developed for detecting the distribution of sub-sea-floor electrical by: Polymetallic nodules, also called manganese nodules, are rock concretions on the sea bottom formed of concentric layers of iron and manganese hydroxides around a core. As nodules can be found in vast quantities, and contain valuable metals, deposits have been identified as having economic interest.

    deposits, as of polymetallic sulfides [2], [5]. In this part of the paper, these types of deposits broadly categorized into two main groups, namely polymetallic massive sulfide ores and manganese nodules/cobalt-rich crusts. Polymetallic massive sulfides Since , seafloor polymetallic sulfides have been.

Goldfarb, Erin E. Marsh, Thomas Monecke.

      Polymetallic massive sulfides on the modern seafloor have been found in diverse volcanic and tectonic settings at water depths ranging from about to m. These deposits are located at fast-, intermediate-and slow-spreading mid-ocean ridges, on axial and off-axis volcanoes and seamounts, in sedimented rifts adjacent to continental margins and in subduction-related back-arc Cited by: Discoveries of new types of marine mineral occurrences during the last decade, and specifically the massive sulfide deposits at spreading ridges on the ocean floor, have significantly advanced geologic concepts about the origin of ore deposits in a very short period of time. These discoveries also.

Simultaneous leaching of seafloor massive sulfides (SMS) from Loki’s Castle on the Arctic Mid-Ocean Ridge (AMOR) and polymetallic nodules (PN) from Clarion Clipperton Zone (CCZ) of the Central Pacific Ocean was studied. Leaching tests were conducted using sulfuric acid and sodium chloride, at a temperature of 80 °C for 48 h under reflux.

Polymetallic sulfide deposits are formed by hot (up to °C) seawater rising through the seafloor and precipitating leached metals in the form of submarine chimneys (‘black smokers’) or domes.
