    Chemical composition of oxide-phosphorite pavement from the Blake Plateau under various preparation treatment (1982)
    PANGAEA
    In:  Supplement to: Commeau, J A; Manheim, Frank T (1982): Testing the variation of Fe-Mn concentration as a function of preparation treatment for phosphate-manganese nodules from the Blake Plateau. (Expedition GYRE 82-11), Cruise Note. USGS Woods Hole Coastal and Marine Science Center

    Description: Sample preparation technique is critical for valid chemical analyses. A main source of error comes from the fact that the great specific surface area of crusts or nodules enhances their tendency to retain or attract hygroscopic moisture. Variable treatment of this moisture can in extreme cases lead to analytical value differences as great as 40-50 %. In order to quantify these influences, samples of ferromanganese oxide-phosphorite pavement from the Blake Plateau have been subjected to various drying techniques before analysis using X-ray fluorescence.

    Observations and rare earth element composition of manganese nodules during Atlantis cruise AT266, Blake Plateau (1980)
    PANGAEA
    In:  Supplement to: Manheim, Frank T; Pratt, Richard M; McFarlin, P F (1980): Composition and origin of phosphorite deposits of the Blake Plateau. In: Bentor, Y.K. (Ed.), Marine Phosphorites - Geochemistry, Occurrence, Genesis, Society of Economic Paleontologists and Mineralogists, Special Publication, 29, 117-137, https://download.pangaea.de/reference/80812/attachments/Manheim-etal_1980.pdf

    Publication Date: 2023-08-28
    Description: An area of about 22,000 km² on the northern Blake Plateau, off the coast of South Carolina, contains an estimated 2 billion metric tons of phosphorite concretions, and about 1.2 billion metric tons of mixed ferromanganese-phosphorite pavement. Other offshore phosphorites occur between the Blake Plateau and known continental deposits, buried under variable thicknesses of sediments. The phosphorite resembles other marine phosphorites in composition, consisting primarily of carbonate-fluorapatite, some calcite, minor quartz and other minerals. The apatite is optically pseudo-isotropic and contains about 6% [CO3]**2- replacing [PO4]**3- in its structure. JOIDES drillings and other evidence show that the phosphorite is a lag deposit derived from Miocene strata correlatable with phosphatic Middle Tertiary sediments on the continent. It has undergone variable cycles of erosion, reworking, partial dissolution and reprecipitation. Its present form varies from phosphatized carbonate debris, loose pellets, and pebbles, to continuous pavements, plates, and conglomeratic boulders weighing hundreds of kilograms. No primary phosphatization is currently taking place on the Blake Plateau. The primary phosphate-depositing environment involved reducing conditions and required at least temporary absence of the powerful Gulf Stream current that now sweeps the bottom of the Blake Plateau and has eroded away the bulk of the Hawthorne-equivalent sediments with which the phosphorites were once associated.

    Annotated record of the detailed examination of Mn micronodules from stations over George Bank, Atlantic Ocean (1984)
    PANGAEA
    In:  Supplement to: Poppe, L J; Commeau, R F; Commeau, J A; Manheim, Frank T; Aruscavage, P J (1984): Ferromanganese micronodules from the surficial sediments of Georges Bank. Journal of Marine Research, 42(2), 463-472, https://doi.org/10.1357/002224084788502765
    Details
    Publication Date: 2023-08-28
    Description: Ferromanganese micronodules have been found on Georges Bank, off the U.S. northeast coast, distributed throughout the surficial sediments within an area about 125 km long and at least 12 km wide. These coarse, sand-sized concretions have precipitated from metal-rich interstitial waters and contain many of the textural and structural features common to other neritic nodules. Most of the nodules have accreted around detrital grains, and X-ray powder diffraction analyses indicate the presence of geothite and vernadite ( delta -MnO sub(2)) in the ferromanganese layers. Chemical analyses of the micronodules, when compared with similar data on deep-sea manganese nodules, reveal lower Mn/Fe ratios, significantly higher concentrations of V and As, comparable values of Mo, and an order of magnitude less of Co, Ni, Ce and most other, metals.
