    Description and iron and manganese content of ferromanganese nodules from Oneida Lake, NY (1981)
    PANGAEA
    In:  Supplement to: Moore, Willard S (1981): Iron-manganese banding in Oneida Lake ferromanganese nodules. Nature, 292(5820), 233-235, https://doi.org/10.1038/292233a0

    Description: Ferromanganese nodules in the deep-sea and in freshwater lakes usually accrete layers rich in manganese oxides alternating with layers rich in iron oxides. The mechanism producing these alternating layers is unknown; indeed, the mechanism producing the nodules themselves is unknown. In Oneida Lake, New York, precipitants from the lake water and the surfaces of nodules at the sediment-water interface are enriched in Mn, whereas nodules buried in lake sediments have surface layers enriched in Fe. It is hypothesized here, using field and laboratory evidence, that reduction and mobilization of Mn from the nodule surface during periods of anoxic sediment cover produce the high Fe layers observed in the nodules.

    Chemical composition of manganese nodule samples from the North Pacific Ocean (1981)
    PANGAEA
    In:  Supplement to: Bischoff, James L; Piper, David Z; Leong, Kam (1981): The aluminosilicate fraction of North Pacific manganese nodules. Geochimica et Cosmochimica Acta, 45(11), 2047-2063, https://doi.org/10.1016/0016-7037(81)90059-4

    Description: Nine nodules collected from throughout the deep North Pacific were analyzed for their mineralogy and major-element composition before and after leaching with Chester-Hughes solution. Data indicate that the mineral phillipsite accounts for the major part (〉 75%) of the aluminosilicate fraction of all nodules. It is suggested that formation of phillipsite takes place on growing nodule surfaces coupled with the oxidation of absorbed manganous ion. All the nodules could be described as ternary mixtures of amorphous iron fraction (Fe-Ti-P), manganese oxide fraction (Mn-Mg Cu-Ni), and phillipsite fraction (Al-Si-K-Na), these fractions accounting for 96% of the variability of the chemical composition.

    Detailed description, geochemistry and radioactivity of manganese nodules taken during the R/V Vityaz cruise to the Indian Ocean (1962)
    PANGAEA
    In:  Supplement to: Kalinenko, V O; Belokopytova, O V; Nikolaeva, G G (1962): Bacteriogenic formation of iron-manganese concretions in the Indian Ocean. Okeanologiya, 11(6), 1050-1059, hdl:10013/epic.46647.d001

    Publication Date: 2023-08-28
    Description: During the 33th voyage of the R/V "Vityaz" in the Indian Ocean iron-manganese nodules were collected at several stations. Both nodules and associated sediments were analysed by spectral analysis over 30 chemical elements. Radioactivity measurements were also performed on these samples.

    Chemical composition of Lake George (New York) iron-manganese nodules and underlying sediment (1971)
    PANGAEA
    In:  Supplement to: Schoettle, Manfred; Friedman, Gerald M (1971): Fresh water iron-manganese nodules in Lake George, New York. Geological Society of America Bulletin, 82(1), 101-110, https://doi.org/10.1130/0016-7606(1971)82%5B101:FWINIL%5D2.0.CO;2

    Description: Lake George, New York, is the site of a new discovery of iron-manganese nodules. These nodules occur at a water depth between 21 and 36 m along a stretch of lake extending for about 5 mi north and south of the Narrows, a constricted island-dotted area which separates the north and south Lake George basins. Nodules occur on or within the uppermost 5 cm of a varved glacial clay. Some areas are solidly floored with a carpet of nodules in areas where active currents keep the nodules exposed. The nodules form around nuclei which consist of clay and less commonly of spore capsules, detrital particles, or bark. By their shape we recognize three types of nodules: spherical, discoidal, and lumps. On X-ray examination all nodules show small goethite peaks; in one nodule the manganese mineral birnessite was identified. Manganese and part of the iron appears to be in X-ray amorphous ferromanganese compounds. The Lake George nodules are enriched in iron with respect to marine nodules but are lower in manganese. They have a higher trace element concentration than nodules from other known freshwater lake occurrences, but a lower concentration than marine nodules.
