Description:
Some manganese samples (two crusts and two nodules) dredged around 1,000 m depth on the southern slope of the Tuamotu Archipelago have shown five associations of calcareous nannofossils, which are either included in or printed into the cortex and the nucleus. The location and the age of these associations let us reconstitute the full story of the samples. The growth of the incrustations occurred mainly during two periods: the first one between the middle Eocene and the basal Oligocene, the second one between the upper Pliocene and the Recent.
