Major elements geochemistry of manganese nodules from the Pacific Ocean, supplement to: Piper, David Z; Basler, J R; Bischoff, James L (1984): Oxidation state of marine manganese nodules. Geochimica et Cosmochimica Acta, 48(11), 2347-2355


Analyses of the bulk oxidation state of marine manganese nodules indicates that more than 98% of the Mn in deep ocean nodules is present as Mn(IV). The samples were collected from three quite different areas: the hemipelagic environment of the Guatemala Basin, the pelagic area of the North Pacific, and seamounts in the central Pacific. Results of the study suggest that todorokite in marine nodules is fully oxidized and has the following stoichiometry: (K, Na, Ca, Ba)0.33 (Mg, Cu, Ni)0.76 Mn5 O22 (H2O)3.2.

Analysis was performed on the soluble part in a 0.03 M H2C2O4 and 0.1 M H2SO4 acid solution.
