    Annotated record of the detailed examination of Mn deposits from DSDP Leg 39 (Holes 354, 355, 356, 358, 359) (1977)
    PANGAEA
    In:  Supplement to: Perch-Nielsen, Katharina; Supko, Peter R; Boersma, Anne; Bonatti, Enrico; Carlson, Richard L; McCoy, Floyd W; Neprochnov, Yuri P; Zimmerman, H B (1977): Initial Reports of the Deep Sea Drilling Project. U. S. Government Printing Office, XXXIX, 1139 pp, https://doi.org/10.2973/dsdp.proc.39.1977

    Description: Unlike most previous Deep Sea Drilling Project cruises, Leg 39 was not scientifically planned as a "theme" cruise, on which a number of sites are drilled to address a single scientific problem area, namely, to improve our knowledge of paleocirculation changes and the overall geologic history of the South Atlantic Ocean. This would be done along more specific objectives: 1) collect a biostratigraphic section on the Ceará Rise (Site 354), determine the nature and age of a prominent reflector there, and determine the nature and age of basement; 2) date basement between magnetic anomalies 32 and 33 in the Argentine Basin (Site 358), and 33 and 34 in the Brazil Basin (Site 355); obtain as complete sedimentary sections as time would permit at the Ceará Rise, Brazil Basin, the Argentine Basin and Sào Paulo Plateau (Site 356).

    (Table 1, page 345) Organism borrowing into manganese nodules from the Blake Plateau area (1977)
    PANGAEA
    In:  Duke University | Supplement to: Furbish, William J; Schrader, Ed L (1977): Secondary biogenic textures in some iron—Manganese nodules from the Blake Plateau, Atlantic Ocean. Marine Geology, 25(4), 343-354, https://doi.org/10.1016/0025-3227(77)90062-7
    Details
    Publication Date: 2023-08-28
    Description: Eighty-seven manganese nodules, representing 6 different locations at depths ranging from 2400 to 7400 m, from the eastern edge of the Blake Plateau were studied. Most of the nodules contained secondary structural textures resulting from the apparent burrowing of marine microfauna. This biogenic activity produced modification of the original growth patterns. In many cases the burrowed zones served as favored sites for redeposition of iron-manganese material. Transmitted light and scanning electron microscope analysis revealed the presence of 3 types of organic activity: (1) agglutinated foraminiferal tests; (2) pre-bored clay particles acting as nuclei or later included during nodule growth; and (3) younger burrows that cross-cut all older structures. In many instances this cross-cutting action resulted in almost total eradication of areas of the original growth patterns. The final texture may be mistaken for a similar growth texture previously classified as mottled, but a more specific genetic term might be 'disrupted'.
