What do we really know about the role of microorganisms in iron sulfide mineral formation?
Iron sulfide mineralization in low-temperature systems is a result of biotic and abiotic
processes, though the delineation between these two modes of formation is not always …

Multi-metal contaminant dynamics in temporarily flooded soil under sulfate limitation
FA Weber, A Voegelin, R Kretzschmar - Geochimica et Cosmochimica Acta, 2009 - Elsevier
In many river basins, floodplain soils have accumulated a variety of metal contaminants,
which might be released during periods of flooding. We investigated the dynamics of copper …
