    Contents of metal cations exchange capacity of ore minerals in ferromanganese micronodules from the Atlantic, Indian and Pacific Oceans
    PANGAEA
    In:  Supplement to: Novikov, Georgy V; Sval'nov, Vyacheslav N; Bogdanova, Olga Yu; Sivtsov, Alexander V (2010): Ion exchange properties of manganese and iron minerals in oceanic micronodules. Translated from Litologiya i Poleznye Iskopaemye, 2010, 5, 461-476, Lithology and Mineral Resources, 45(5), 410-424, https://doi.org/10.1134/S0024490210050020

    Description: Results of experimental studies of ion exchange properties of manganese and iron minerals in micronodules from diverse bioproductive zones of the World Ocean were considered. It was found that sorption behavior of these minerals was similar to that of ore minerals from ferromanganese nodules and low-temperature hydrothermal crusts. The exchange complex of minerals in the micronodules includes the major (Na**+, K**+, Ca**2+, Mg**2+, and Mn**2+) and subordinate (Ni**2+, Cu**2+, Co**2+, Pb**2+, and others) cations. Reactivity of theses cations increases from Pb**2+ and Co**2+ to Na**+ and Ca**2+. Exchange capacity of micronodule minerals increases from alkali to heavy metal cations. Capacity of iron and manganese minerals in oceanic micronodules increases in the following series: goethite 〈 goethite + birnessite 〈 todorokite + asbolane-buserite + birnessite 〈 asbolane-buserite + birnessite 〈 birnessite + asbolane-buserite 〈 birnessite + vernadite ~= Fe-vernadite + Mn-feroxyhyte. Obtained data supplement available information on ion exchange properties of oceanic ferromanganese sediments and refine the role of sorption processes in redistribution of metal cations at the bottom water - sediment interface during micronodule formation and growth.

    Description: A complex of mineralogical techniques used in studies of near-surface layer hemipelagic sediments indicates that disordered todorokite and hexagonal birnessite dominate in manganese micronodules, whereas hexagonal birnessite is the main phase of micronodules from miopelagic sediments. Content of todorokite increases downward through the miopelagic sedimentary sequence; this can be reasonably explained by transformations of some other manganese minerals to todorokite. Occurrence of several manganese minerals in studied samples may reflect temporal and lateral variations in C_org content in sediments and respective local fluctuations in environmental conditions (pH, Eh, geochemical activity of Mn, etc.). Todorokite may have formed under the most anoxic conditions near the water-sediment interface.

    Description: It has been established (with use of analytical electron microscopy) that Fe-Mn crusts from two seamounts of the Sea of Japan consist predominantly of an association of birnessite minerals including Ca-birnessite and clinobirnessite. The latter is represented by twins, which form regular integrowths with 14 Å Ca-birnessite. Ore material from the third seamount (Tarasov submarine volcano) consists only of fibrous todorokite, which forms spherulitic nodules, blocks, and laminar formations. Its chemical composition is close to that of todorokite from the Galapagos rift zone.
