For this purpose samples from Sites 360, 361, 362, 363, and 364 have been examined using classical analysis methods (grain size, amount of CaCO3, smear slides, etc.), and the Scanning Electron Microscope (SEM). The methods of nannofacies study and interpretation used here were previously described by Noël (1969, 1970).Each sample will first be described in general, then observations will be given. Because of poor induration of the samples, only freshly broken surfaces but no polished surfaces were examined by SEM after coating with gold palladium.
