Special Issue Information

Dear Colleagues,

Ferromanganese Nodules & Crusts have been extensively studied for their potential to reconstruct the paleo–ocean environment, as they possess properties that reflect environmental changes.

This Special Issue will focus on the diverse analytical methods employed in the analysis of mineralogical and geochemical ferromanganese Nodules & Crusts and their implications for paleo–ocean environment reconstruction. Please see the list of potential topics below.

  • Section 1. Reconstruction of the Paleo–ocean Environments.
    - The paleo–ocean environmental relationship between geochemical and mineralogical properties of ferromanganese Nodules & Crusts.
    - New approaches to unravel the genesis and formation mechanisms of ferromanganese Nodules & Crusts.
    - Comparative analysis of ferromanganese Nodules & Crusts with various seafloor deposits.
  • Section 2. Biogeochemistry of deep-sea environments.
    - Microbe–mineral interaction in deep-sea
    - Tracking the microbial mineral alteration in deep-sea and hydrothermal systems.
    - Environmental monitoring and baseline studies.
  • Section 3. Crystallography of ferromanganese oxide.
    - Methods and case studies on crystal structure evolution and the formation of minerals by enriching Ni, Co, etc., elements into lattice during paleo–environmental change.
  • Section 4. General properties of ferromanganese nodule
    - Novel analytical methods for analyzing the geochemical and mineralogical properties of ferromanganese Nodules & Crusts.
    - Advances in qualitative and quantitative analysis techniques for ferromanganese Nodules & Crusts.

The geochemistry and mineralogy of Mn nodules offer crucial insights into the origins, environmental changes, and distribution of abyssal resources. However, the conventional laboratory X-ray diffractometer, usually employed for semi-quantitative analysis of mineral composition in Mn nodules, often fails to sufficiently detect minor phases due to beam flux limitations and high background signals. In this study, we investigated differences in manganate composition, even when comprising around 1% of the phase fraction, in two manganese nodules (KC-8 and KODOS-10) using high-resolution synchrotron X-ray diffraction. The Mn/Fe ratios of KC-8 and KODOS-10 were 1.32 and 6.24, respectively, indicating that KC-8 and KODOS-10 were predominantly formed in hydrogenetic and diagenetic environments. Both samples contained quartz, vernadite, buserite, and feldspar. Todorokite and illite were exclusively observed in KODOS-10. In KC-8, the phase fractions of vernadite and buserite among manganates ranged from 94(5)%–100(4)% and 6(1)%–0%, respectively. However, in KODOS-10, the fractions of vernadite, buserite, and todorokite ranged from 47(1)%–56(2)%, 33.6(4)%–40.1(3)%, and 10(3)%–16.3(8)%, respectively. Full article

A new X-ray fluorescence technique is proposed as an alternative to the labor-consuming volumetric method for the estimation of manganese valence state in ferromanganese nodules. The approach is based on the measurement of the relative intensities of some X-ray fluorescence spectrum characteristic spectral lines and satellites (MnKβ5 and MnKβ′) preconditioned by electron transfer from the valence shell. Calibration curves were created using manganese oxide samples (MnO, Mn2O3, MnO2) and 12 certified reference materials of ferromanganese nodules, cobalt-bearing ferromanganese crusts, and manganese ores with certified (or determined by approved methods) total and tetravalent manganese content. The presence of high iron content was taken into account. A set of oceanic ferromanganese nodules samples collected in the Magellan Seamounts (Pacific Ocean) were analyzed. Differences between the results of the X-ray fluorescence method and volumetric techniques for tetravalent manganese content were 4.9 rel.%, which is comparable with the accuracy of the volumetric technique (3.6 rel.%).
