“…However, only 15 out of 167 hydrothermal deposit sites all over the world were dated by the 230 Th/U method (Hannington et al, 2011). For relatively young sulfides the 210 Pb and the 226 Ra/Ba methods are suited (Finkel, 1980;Lalou et al, 1986;Jamieson, 2013).…”

A geochronological and geochemical study on 10 samples of seafloor massive sulfides (SMS) from the inactive Peterburgskoye hydrothermal field at the Mid-Atlantic Ridge (MAR) was carried out. The 230 Th/U ages of the SMS are the oldest for the Quaternary hydrothermal ores ever found at the ocean floor. According to them the hydrothermal activity at Peterburgskoye field started at least 170 ka and continued down to 63 ka. The oldest hydrothermal ores from this field consist mainly of pyrite and chalcopyrite and have geochemical properties typical for SMS associated with basalts.

“…Usually SMS samples of individual mounds show a great variety in their chemical and mineralogical compositions (Bogdanov et al, 2006;Hannington et al, 2011), but those from the Peterburgskoye field did not. These sulfide ores had three main components: Fe, Cu and S and traces of Zn with very low concentrations of trace elements .…”

“…SMS deposits form through hydrothermal circulation to create areas of hard substratum rich in sulfides and base metals. There are currently 165 deposits known globally (Hannington et al 2011), which occur across a range of hydrothermal settings, as reviewed by Boschen et al (2013).…”

“…Most concretions are concentrated in the center of the Pacific Ocean between the latitudinal faults of Clarion and Clipperton along the equator for thousands of kilometers. In addition to the Clarion-Clipperton areas with high concentrations of ferromanganese formations are also found in the central Indian Ocean, in the seas of the Arctic Ocean, in the southern and southeastern parts of the Pacific Ocean [7][8][9][10][11][12][13].…”

Abstract. The world ocean has huge reserves of minerals that are contained directly in the water, as well as on the surface of its bottom and in its subsoils. The deposits of solid minerals on the surface of the bottom of the World Ocean are considered the most promising for industrial extraction. The deposits of ferromanganese nodules, cobalt-manganese crusts and polymetallic sulphides are considered as an object of extracting more often than others. There are the largest deposits of ferromanganese nodules in the central and southern parts of the Pacific Ocean, in the central part of the Indian Ocean, and in the seas of the Arctic Ocean near Russia. The deposits of ferromanganese nodules are a serious alternative to deposits of manganese ore on land. However, there are many factors influencing the efficiency of the development of ferromanganese deposits, the most significant are: the content of the useful component in the ore, the depth of the bottom and the distance from the seaports. It is also necessary to take into account the possible environmental consequences of underwater mining.
