calcareous deposits formed on the part of steel that cathodic reactions occur on their surface. the purpose of this research is an investigation of the effect of potential on crystal form of the calcareous deposits and effect of them on the corrosion resistance of the mild steel in natural seawater. the electrochemical tests such as impedance and polarization tofel tests were used in order to i...
a succession of late campanian- early maastrichtian is analyzed from gurpi formation with regard to the calcareous nannofossils. correlation matrix was applied for the first time to the entire nannofossil assemblage to reconstruct environmental conditions. a detailed quantitative calcareous nannofossil analyses is performed on samples in order to further investigate the climate events, and inte...
