Controls on the chemical composition of ferromanganese

2019-3-1  The chemical composition of individual microlayers within the nodules was determined by laser ablation ICP-MS. Analyses were carried out on 100 μm-thick polished sections using a 193 nm excimer laser (New Wave Research model UP193X) coupled to a quadrupole ICP-MS (Thermo X-Series II) at the University of Southampton.

2021-5-20  However, until the middle of the XX century, only the chemical composition of crusts was analyzed. It was found out that ferromanganese crusts consist of up to 20% Mn, 15% Fe and 0.3–2.5% Co. In addition, they can contain complexes of noble, non-ferrous, rare and rare earth metals (up to 70 elements). All this data obtained stimulated further

Ferromanganese nodules from MANOP Sites H, S, and R

The chemical composition of ferromanganese nodules from the three nodule-bearing MANOP sites in the Pacific can be accounted for in a qualitative way by variable contributions of distinct accretionary processes. These accretionary modes are: (1) hydrogenous, i.e., direct precipitation or accumulation of colloidal metal oxides in seawater, (2) oxic diagenesis which refers to a
