Abstract
RECENT discussions1 on the nature of 3d transition-metal ions in sea water and in manganese nodules have rejected the possibility that oxidation of cobalt to Co (III) occurs in marine environments. A detailed electron microprobe study of manganese nodules2 from diverse geographical localities supports the belief3 that there is a cobalt–iron inter-element relationship in the nodules. Cobalt is enriched in the X-ray amorphous FeOOH.nH2O phase in those nodules which contain appreciable amounts of iron. The results indicate that Co (III) and Fe (III) constitute an ‘isomorphous’ pair in the amorphous (Fe,Co)OOH.nH2O phase, which may be recrystallized to geothite on treatment with hydroxylamine hydrochloride.
