    (Table 1) Minerals found in vesicles and fractures from DSDP Leg 54 Holes basalts
    PANGAEA
    In:  Supplement to: Furbish, William J; Schrader, Ed L (1980): Secondary minerals of deuteric and diagenetic origin filling voids and encrusting surfaces on basalts from Deep Sea Drilling Project Leg 54. In: Rosendahl, BR; Hekinian, R; et al. (eds.), Initial Reports of the Deep Sea Drilling Project (U.S. Govt. Printing Office), 54, 807-817, https://doi.org/10.2973/dsdp.proc.54.136.1980

    Description: A variety of secondary minerals, formed in response to different oxidation and hydration states, are found in vugs and on fracture surfaces of the basalt cores from DSDP Leg 54. The minerals are smectite (blue to grey), high-magnesium calcite, manganoan calcite, aragonite, iron oxides, phillipsite, todorokite, marcasite, and hydrobiotite. The relationship of the mineral assemblages to four depositional modes of the basalts are delineated. A definite sequence and genetic link exists between mineral type and host rock which is dependent upon the origin and subsequent cooling history of the basalt.

    (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

    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'.
