Abstract
An unusual low-water corrosion of steel sheet piles has been systemati cally investigated in a channel harbour (Boulogne sur Mer, France), An analysis of the environment reveals that all sampling of dark rust ta ken at different heights above marine sediments and kept in anaerobic conditions present unusual concentrations of sulfate-reducing bacteria . The rust products have been characterized by Mossbauer spectroscopy and Xray diffraction, comprising the ferrous-ferric sulfated compounds of formula 4Fe(OH)(2).2FeOOH.FeSO4.nH(2)O, called green rust 2, mixed sometimes with magnetite and a small amount of ferrous sulfide.
