Mini-review: The Morphology, Mineralogy and Microbiology of Accumulated Iron Corrosion Products.

摘要

Despite obvious differences in morphology, substratum chemistry and the electrolyte in which they form, accumulations of iron corrosion products have the following characteristics in common: stratification of iron oxides/hydroxides with a preponderance of -FeOOH (goethite) and accumulation of metals. Bacteria, particularly iron-oxidizing and sulfatereducing bacteria have been identified in some accumulations. Both biotic and abiotic mechanisms have been used to rationalize observations for particular sets of environmental data. This review is the first to compare observations and interpretations.
