    Analysis of manganese crusts from Galapagos (1976)
    PANGAEA
    In:  Supplement to: Moore, Willard S; Vogt, Peter R (1976): Hydrothermal manganese crusts from two sites near the Galapagos spreading axis. Earth and Planetary Science Letters, 29(2), 349-356, https://doi.org/10.1016/0012-821X(76)90139-4

    Beschreibung: Manganese oxide crusts similar to those reported from the Mid-Atlantic Ridge rift valley by Scott et al., 1974 (https://doi.pangaea.de/10.1594/PANGAEA.848726) were dredged at two sites near the Galapagos spreading axis on ocean floor estimated from magnetic anomalies to be 2.4 and 0.3 m.y. old. Compared to the typical ocean-floor manganese deposits attributed to precipitation from seawater, the 2-6 cm thick manganese crusts reported here exhibit very low Fe/Mn and low 232Th/238U ratios, as well as lower transition metal and higher manganese concentrations. The manganese crusts were deposited several orders of magnitude faster than the more common hydrogenous nodules; this fact together with other geochemical characteristics and the geophysical environment suggests the manganese deposits reported here are of hydrothermal origin.

    Description and chemical analysis of manganese nodules from the Pacific Ocean (1976)

    Beschreibung: Analyses of small samples extracted from different parts of a single manganese nodule have been reported by several investigators, clearly documenting the belief that a nodule is not homogeneous chemically, as a rule. The same sort of evidence has been gathered by use of the X-ray macroprobe and electron microprobe analyses. The X-ray probe work has shown clearly that chemical variations within a nodule can be correlated with optically recognizable mineral,and therefore optical study can tell much about chemical variations and obviate much probe analysis. As we have reported many times, optically anisotropic crystalline todorokite and birnessite contain the bulk of the Mn, Ni, and Cu in any nodule whereas optically isotropic and X-ray amorphous oxides contain most of the Fe and Co in the same nodule.

    Geochemistry on manganese nodules from the Southern Ocean (1976)
    PANGAEA
    In:  Supplement to: Meylan, Maurice A; Goodell, H G (1976): Chemical composition of manganese nodules from the Pacific-Antarctic Ocean, Drake Passage and Scotia Sea - Relation to ferromanganese oxide mineralogy and nucleus type. in: Glasby, G.P., Katz, H.R.

    Beschreibung: Manganese nodules from the Scotia Sea and Pacific Ocean sectors of the Southern Ocean display regional differences in chemical and mineralogical composition. Mn/Fe and todorokite/delta-MnO2 ratios decrease southeasterly from the Southwestern Pacific Basin to the Drake passage-Scotia Sea. Relative to Mn, the greatest enrichments of Co, Ti, V, Zn, Mo and Sn occur in Drake Passage-Scotia Sea nodules, while Ni and Cu are most enriched in the Southwestern Pacific Basin. Manganese mineralogy is directly related to the Mn/Fe ratio, so that todorokite rather than delta-MnO2 predominates when high manganese vs iron contents are found. Trace metal contents are also related to mineralogy, with high values of Ni, Cu, Zn and Sn, and low values of Co, Ti, V and Mo associated with high todorokite contents. Nodules having indistinct zeolitits/vesiculite nuclei tend to have Mn/Fe and todorokite/delta-MnO2 ratios significantly higher than average for the region in which they are found, whereas ferromanganese oxide fragments dredged from submarine rock surfaces usually have Mn/Fe and todorokite/delta-MnO2 ratios lower than regional average.

    Beschreibung: In 1975 Washington State University was contracted by the U. S. Geological Survey to conduct a study of manganese nodules collected during cruises of the DOMES project of NOAA. The nodule research was to be restricted to problems related to DOMES objectives and was not to include a study of problems of nodule distribution and origin. The project was to be coordinated with mineralogical and chemical investigations carried out simultaneously in Geological Survey laboratories. This report concerns only the RP6-OC-75 samples. The body of the report describes the nature of the major types of surface features of nodules and includes numerous illustrations of of typical nodules. To provide a wider coverage of nodule types in the collection, and to record some of the gross physical data on the nodules, an illustrated Appendix is also included.

    Beschreibung: The GEORSTOM III CENTRE expedition on the R/V Noroit surveyed the Coral Sea around the New Hebrides Islands and the Erromango Plateau from 17 until 26 October 1975. This report offers a description of the dredging sites, the macroscopic and microscopic determinations of samples, the chemical analyzes of rocks, the electron microprobe and micropaleontological determinations, the photographic plates and the preliminary conclusions.
