    Analytical results for sulfur and carbon in manganese nodules from the GH80-1 cruise in the north to south central Pacific Ocean (2023)
    PANGAEA
    Details
    Publication Date: 2023-08-28
    Description: In this study, 111 manganese nodules from the north and south Central Pacific were analyzed for total sulfur and total carbon. The samples had been collected along two tracks of 2000 km long for each, running from east of the Wake island to west of Tahiti in the cruise GH80-1, Geological Survey of Japan. For the purpose of removing adherent sea salt, all nodules were immersed in running water and then ion-free water. Air-dry nodules were ground to under 150 mesh. The ground samples were dried at 110 °C for 3 hours, then removed into 40 ml of plastic bottles and kept in a desiccator. In most cases, the analyzed samples were prepared from the mixture of two or three nodules having different sizes for each group of samples collected with a box corer or a freefall grab. Two instrumental methods were used to determine the concentrations of the elements under consideration: (i) Infrared absorption photometry after combustion at 1800°C for total sulfur, total carbon and non-carbonate carbon; (ii) Atomic absorption spectrometry for manganese, sodium, calcium and barium. The coefficient of variation of the infrared absorption photometry after combustion was 5-10%, and that of the atomic absorption spectrometry was 3-5%.

    Chemical composition of manganese nodules from GH78-1 cruise (2023)
    PANGAEA
    Details
    Publication Date: 2023-09-26
    Description: Fifty-seven samples of manganese nodules from the GH78-1 area were analysed in bulk rock for major and some minor metal elements to provide the data for the evaluation of the chemical features of the nodules. Air-dried sample of 0.1 g was decomposed with a mixture of 5 ml of hydrochloric acid and 5 ml of nitric acid in a covered 50 ml beaker on a boiling bath for about 30 minutes. After cooling, the solution was filtered into a 100 ml calibrated flask and diluted to the mark with water. The analyses for Mn, Fe, Co, Ni, Cu, Zn and Pb were done by atomic absorption spectrometry. The total water was analyzed gravimetrically.

    Chemical composition of manganese nodules from GH80-1 cruise (2023)
    PANGAEA
    Details
    Publication Date: 2023-09-26
    Description: 67 samples of manganese nodules were obtained during the GH79-1 Cruise of R/V Hakurei Maru in the northern part of the Central Pacific Basin. All nodules were immersed in running water and then ion-free water. After air-dried, samples were ground to under 150 mesh. The ground samples were encased in small paper bags, dried at 20-25°C for 24 hours, and then kept in a desiccator. In most cases an analysis was done for mixed ground sample of two or three different size classes of nodules from each box corer or freefall grab. Mn, Fe, Ni, Cu, Co. Pb, and Zn were determined by atomic absorption spectrometry. Each sample of 0.1 g was decomposed with a mixture of 5 ml of hydrochloric acid and 5 ml of nitric acid in a covered 50 ml beaker on a boiling water bath for about 30 minutes. After cooling, the solution was filtered into a 100 ml calibrated flask and diluted to the mark with water. The atomic absorbance of each element in the sample solution was measured using an atomic absorption spectrometer using an air-acetylene flame.

    Details
    Publication Date: 2023-08-28
    Description: 103 nodule samples from each station of the GH81-4 survey from R/V Hakurei Maru were split; one half for microscopy on polished sections and one half for X-ray diffraction (XRD) and chemical analyses. The latter half was powdered in air and subjected to XRD analysis. The powder samples were analyzed for Mn, Fe, Cu, Ni, Co, Pb, Zn, Si, and A1 by atomic absorption spectroscopy after borate/carbonate fusion and HC1 dissolution. All concentrations were shown at ll0 C dried base after measurement of water contents (H20-) and LOI (H20+).

    Description: Local variability of manganese nodule facies and associated sediments were studied around abyssal hills (60 x 60 km²) located in the equatorial zone of the Central Pacific Basin. Small-scale variations in nodule occurrence, mineralogy, chemistry, and internal structure are discussed in relation to seismic records and sediment lithology. The slow sedimentation rate from the late Tertiary to the Quaternary appear to have promoted formation of nodules around the abyssal hills, although the Plio-Pleistocene hiatus at depths below sediment surface suggests no clear evidence of increased growth of nodules during the period. In the area of rapid and continuous sedimentation away from the hill areas, nodules are rare probably because of insufficient lifting force for nodules. Mineralogical and chemical studies reveal that the two principal nodule morphologies (smooth and rough surfaces) result from preferential deposition of hydrogenous or diagenetic manganese minerals in relation to early diagenesis of surface siliceous sediments. Regional variability of nodule-surface morphology and composition suggests a very local change in sedimentary conditions in space, and internal mineral variation suggests changes in sedimentary conditions with time. The geological factors controlling the small-scale variability of nodule facies seem to be similar to those controlling regional-scale variations.

    Description: During the ten R/V Hakurei-Maru cruises from 1984 through 1988 in the Northwestern Pacific island-arc area, a widespread occurrence of hydrogenetic iron-manganese crusts and nodules and hydrothermal manganese deposits were discovered. During shipboard survey, the wet iron-manganese minerals were stored with sea water in a refrigerator immediately after recovery from a sampler, in order to prevent mineralogical transformation on air drying. The subsamples, in both wet and air-dried conditions, were subjected to X-ray powder diffraction (XRD) analysis to ascertain structural stability upon dehydration. Powder samples dried at 110°C for 3 hours were analyzed for metal concentration by atomic absorption spectroscopy according to the Geological Survey of Japan (GSJ) standard analytical technique.

    Notes: Analytical data compiled on nine Geological Survey of Japan (GSJ) reference samples, “Sedimentary rock series” received by February 1996 are reported. After excluding outliers and examining critically the analytical procedures employed, the data were evaluated statistically. Recommended or preferable values for fifteen major and sixty minor and trace elements are proposed.
