Notes: Sediment types: 1 = nannofossil-foraminifer ooze; 2 = banded calcareous silty clay, a = dark interval, b = light interval; 3 = interlaminated micrite and micritic silty clay; 4 = micrite; 5 = micritic silty clay; 6 = calcareous silty sand. Rel. int. = intensity of peak relative to largest peak present in pattern.
