Journal of Raman Spectroscopy, Volume 56, Issue 10, Page 1072-1088, October 2025.Manganese oxides are important geomaterials with diverse technological applications. Here, we investigate the behaviour of the most common Mn oxides with layer structures under irradiation by a 532‐nm laser, with intensity ranging from 23 µW/µm2 to 36.8 mW/µm2.

Geophysical Research Letters, Volume 52, Issue 16, 28 August 2025.Abstract Accurate age determination of marine ferromanganese (Fe‐Mn) nodules is crucial for interpreting their geochemical compositions as paleoceanographic tracers and for understanding critical metal (e.g., Co, Ni) enrichment. Previous empirical dating methods, primarily developed for deep‐ocean nodules, are less effective in marginal seas with high ...
