ISW, Central Indian Ocean
 
Description Fiftyseven ferromanganese nodules, classified into 3 size class (4,4-6 and 6-8 cm diam.), from the siliceous sediments of central Indian Ocean were analysed for transition metals and representative sample from each size class for mineralogy. Smaller (4cm diam.) nodules are invariably rough and very rough and spherical; they have higher concentration of Mn, Ni and Cu. The intensity of todorokite reflection decreases in higher size (4 cm diam.) class. These observations suggest that the smaller nodules appear to have been influenced more by diagenetic processes that the larger nodules
