Iron and Calcium Biomineralizations in the Pampean Coastal Plains, Argentina: Their Role in the Environmental Reconstruction of the Holocene
(Springer, 2018)
Biomineralizations are biogenic composites, crystalline or amorphous,produced by the metabolic activity of organisms distributed all over the world. Theaim of this work was to evaluate the presence of iron and calcium ...
Iron biogeochemistry in Holocene palaeo and actual salt marshes in coastal areas of the Pampean Plain, Argentina.
(Springer, 2016-02)
In salt marshes, the hydrodynamics and the availability of iron, organic matter and sulphate, influence the formation and/or dissolution of iron sulfides and iron oxyhydroxides. Therefore, they constitute key factors ...
