Impact of Redox Cycles on Manganese, Iron, Cobalt, and Lead in Nodules [PDF]

, 2009
International audienceRedox processes are responsible for Fe and Mn segregation as Fe–Mn oxide coatings or nodules. These nodules are also trace element scavengers in soils.

Zircon effect alone insufficient to generate seawater Nd-Hf isotope relationships [PDF]

, 2011
[1] Many studies have suggested that continental weathering inputs have controlled the dissolved oceanic budget of hafnium (Hf). However, whether the offset of seawater Nd‐Hf isotope compositions from the terrestrial array can be fully generated by ...

Structure of nanocrystalline phyllomanganates produced by freshwater fungi [PDF]

, 2010
International audienceThe crystal structures of biogenic Mn oxides produced by three fungal strains isolated from stream pebbles were determined using chemical analyses, XANES and EXAFS spectroscopy, and powder X-ray diffraction.
