Discovery of Dense Ferromanganese Nodules in the Central Basin of the South China Sea: Insights Into Metallogenesis Processes and Resource Potential

Geophysical Research Letters
Ferromanganese deposits in the South China Sea (SCS) hold significant strategic metal resources, yet their distribution remains poorly understood. To address this gap, we conducted an integrated study across 6,600 km2 in the central basin of the SCS ...

A New Method for Calculating Growth Rates of Ferromanganese Nodules From Marginal Seas: Implications for Terrigenous Input in the South China Sea

Geophysical Research Letters
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,

Microbial Communities Associated With Ferromanganese Nodules and the Surrounding Sediments

Frontiers in Microbiology, 2013
The formation and maintenance of deep-sea ferromanganese/polymetallic nodules still remains a mystery 140 years after their discovery. The wealth of rare metals concentrated in these nodules has spurred global interest in exploring the mining potential ...

The Mechanism of Microbial-Ferromanganese Nodule Interaction and the Contribution of Biomineralization to the Formation of Oceanic Ferromanganese Nodules

Microorganisms, 2021
Ferromanganese nodules are an important mineral resource in the seafloor; however, the genetic mechanism is still unknown. The biomineralization of microorganisms appears to promote ferromanganese nodule formation.

The Geochemical Features and Genesis of Ferromanganese Deposits from Caiwei Guyot, Northwestern Pacific Ocean

Journal of Marine Science and Engineering, 2022
The ferromanganese deposit is a type of marine mineral resource rich in Mn, Fe, Co, Ni, and Cu. Its growth process is generally multi-stage, and the guyot environment and seawater geochemical characteristics have a great impact on the growth process ...

Microbe-driven elemental cycling enables microbial adaptation to deep-sea ferromanganese nodule sediment fields

Microbiome, 2023
Background Ferromanganese nodule-bearing deep-sea sediments cover vast areas of the ocean floor, representing a distinctive habitat in the abyss. These sediments harbor unique conditions characterized by high iron concentration and low degradable ...

Rotation of a Ferromanganese Nodule in the Penrhyn Basin, South Pacific, Tracked by the Earth's Magnetic Field

Geochemistry, Geophysics, Geosystems, 2023
Ferromanganese nodules are cm‐sized, authigenic, abyssal manganese‐iron‐hydroxide concretions. They grow very slowly at rates of a few mm per million years.

Microbial Communities of Ferromanganese Sedimentary Layers and Nodules of Lake Baikal (Bolshoy Ushkany Island)

Diversity, 2022
Ferromanganese (Fe-Mn) sedimentary layers and nodules occur at different depths within sediments at deep basins and ridges of Lake Baikal. We studied Fe-Mn nodules and host sediments recovered at the slope of Bolshoy Ushkany Island.

Fast-growing Arctic Fe–Mn deposits from the Kara Sea as the refuges for cosmopolitan marine microorganisms

Scientific Reports, 2022
The impact of biomineralization and redox processes on the formation and growth of ferromanganese deposits in the World Ocean remains understudied. This problem is particularly relevant for the Arctic marine environment where sharp seasonal variations of
