Two different ferromanganese nodule samples were collected from CC area in the East Pacific, one Co-rich crust sample was collected from Magellan seamounts in the West Pacific. According to the data, vernadite and todorokite are the main compositions of ferromanganese nodules, while the Co-rich crust mainly consists of vernadite. Compared with each other, hydrogenic ferromanganese nodule has higher amount of P, Ti, whereas Cu, Ni in diagenetic ferromanganese nodule is higher. The Co-rich crust is depleted in Cu, Al, Na, and rich in Co, compared with ferromanganese nodule samples. The samples are rich in Fe, Mn, Cu, Co, Ni. The content of REE (rare earth elements) is high and the distribution of the REE elements shows positive anomaly of Ce and Eu in all the samples.
