    Chemical analysis of manganese nodules from the Cape Leeuwin field, southeast Indian Ocean (1982)
    PANGAEA
    In:  Supplement to: Frakes, Lawrence A (1982): Metal chemistry of manganese nodules from the Cape Leeuwin field, southeast Indian Ocean. Marine Geology, 47(1-2), M1-M10, https://doi.org/10.1016/0025-3227(82)90014-7

    Description: Manganese nodules from 36 stations in the Cape Leeuwin field were analyzed for Mn, Fe, Ni, Cu and Co and the results were combined with earlier work to demonstrate quantitative and geographic variations. Nodules in this field are moderately enriched in Ni, moderately depleted in Cu, and contain intermediate values of Co. The sum of Ni + Cu vs. Mn/Fe plots along a hyperbolic regression line derived from nodules of the southeastern Pacific, suggesting that this relationship has general applicability. Regional variations in nodule grade (Ni + Cu + Co) assist in defining pathways of Antarctic Bottom Water between the Southeast Indian Ridge and the Wharton basin.

    Description, Beryllium characteristics and chemical composition of manganese nodules from the Pacific Ocean (1983)

    In:  Supplement to: Inoue, Teruo; Huang, Zui-Yao; Imamura, Mineo; Tanaka, Shigeo; Usui, Akira (1983): 10Be and 10Be/9Be in manganese nodules. Geochemical Journal, 17(6), 307-312, https://www.jstage.jst.go.jp/article/geochemj1966/17/6/17_6_307/_pdf

    Description: Depth profiles of 10Be and 9Be concentrations have been measured in five manganese nodules from widely varying locations of the Pacific Ocean. Mean accumulation rate of these manganese nodules ranges from 2.7 to 8.0 mm/m.y.. The variation of 10Be and 10Be/9Be with depth or time is found to be less than ±30% for periods from 0.4-1.0 m.y. back to 6 m.y. B.P. Surface 10Be/9Be atomic ratio is found to be (9-13) x 10**-8, that shows authigenic nature of manganese nodule acuumulation by comparison with (12-31) x 10-8 for deep-sea water, (2-7) x 10**-8 for clay sediments and (7-9) x 10**-8 for fossil-rich sediments.

    Annotated record of the detailed examination of Pacific Ocean Mn deposits and chemical composition of layers inside a manganese nodule from the Gulf of California (1982)
    PANGAEA
    In:  Supplement to: Haynes, Benjamin W; Law, Stephen L; Barron, David C (1982): Mineralogical and elemental description of Pacific manganese nodules. Bureau of Mines, US Department of the Interior, Information Circular, 8906, 60 pp, https://archive.org/details/mineralogicalele00hayn
    Details
    Publication Date: 2023-08-28
    Description: The report is divided into three sections: morphology, mineralogy and elemental composition. The nodule morphology section defines what is considered a nodule for the study, and details the external characteristics and internal structure. Nodule mineralogy is discussed in three sections: manganese minerals, iron oxide minerals, and accessory minerals. The major manganese minerals discussed are todorokite, birnessite, and vernadite. The iron oxide minerals are less well known and include feroxyhyte, goethite, and lepidocrocite. Accessory minerals present include quartz, clays, and other silicates and nonsilicates. A discussion on moisture content is also included. The elemental composition section presents data on 74 elements occurring as cations or anions. Summary data, histograms, and interelement correlation coefficients are presented.
