Abstract : The aim of this research is to study the carbonate sedimentation in a hypersaline coastal (Brejo do Espinho) where dolomite precipitation can be expected. The study allowed to make a general characterization of the sediment and to identify different types of carbonate minerals by mineralogical studies and cryo-scanning electron-microscopy.
