Geochemical processes occurring at a seawater/freshwater interface were studied in a shallow coastal siliclastic aquifer containing minor amounts of calcite. Data were collected from 106 piezometers in a 120-m transect ...
The concept of redox zonation during degradation of organic matter, which is usually explained by the overall energy yield of different reactions, has been reevaluated. At least for reduction of Mn(IV), Fe(III), sulfate, ...
The behaviour of trace amounts of arsenate coprecipitated with ferrihydrite, lepidocrocite and goethite was studied during reductive dissolution and phase transformation of the iron oxides using [55Fe]- and [73As]-labelled ...
